Abstract:
The brachelytrous galerucine genus Shairella Chûjô is reviewed based on examination of 240 specimens. Five new species are described: S. cheni sp. nov., S. chungi sp. nov., S. guoi sp. nov., S. motienensis sp. nov., and S. tsoui sp. nov. The diversity and distribution of most of Shairella species are reflected on one major host plant - Clinopodium laxiflorum var. taiwanianum. Smaller compound eyes relative to otherwise similar galerucines are characteristic for Shairella and may be related to nocturnal behavior. The occurrence of a subapical white band on the antenna and its possible function is discussed.

Abstract:
Studies on spermoderm using scanning electron microscope (SEM) were undertaken in 12 taxa under 11 genera of the family Cucurbitaceae sampled from India, China and Korea. The spermoderm pattern in the studied taxa varies from rugulate, reticulate to colliculate type. The spermoderm shows rugulate type in Benincasa hispida and Sicyos angulatus; reticulate type in Citrullus colocynthis, Cucumis melo var. agrestis, Diplocyclos palmatus, Hemsleya longivillosa, Luffa echinata, Momordica charantia, M. cymbalaria, Schizopepon bryoniifolius, and Trichosanthes cucumerina; and colliculate type in Gynostemma laxiflorum. The present study clearly reveals that the testa features greatly varies across the genera which can be used as micromorphological markers for identification as well as character states for deducing relationship of the taxa within the family.DOI: http://dx.doi.org/10.3329/bjpt.v20i1.15465Bangladesh J.

Abstract:
Les maladies cardiovasculaires sont la principale cause de décès dans le monde. Actuellement, leur prévalence croît en Afrique subsaharienne où l'hypertension représente un facteur de risque cardiovasculaire majeur. Différents médicaments sont utilisés pour le traitement de l'hypertension mais dans les pays à revenu faible en général, et en R.D.Congo en particulier, le niveau socio-économique bas de la population pousse cette dernière à faire appel à la médecine traditionnelle. En R.D.Congo, les tradithérapeutes utilisent une multitude de plantes pour traiter l’hypertension. Cependant, les propriétés pharmacologiques de certaines de ces plantes sur la fonctionnalité vasculaire n’ont pas encore été étudiées de manière approfondie.<p>Afin de donner une base scientifique à l’utilisation de ces plantes dans le traitement de l'hypertension artérielle en médecine traditionnelle congolaise, nous avons réalisé dans un premier temps une enquête ethnobotanique. Celle-ci a été menée auprès de tradipraticiens de Kinshasa et du Bas-Congo, dans l'ouest de la R.D.Congo, afin d'obtenir des informations spécifiques sur les plantes qui sont utilisées pour traiter l'hypertension. Suite à cette enquête, trois plantes ont été sélectionnées :les feuilles et les écorces de racines de Combretum racemosum P. Beauv (Combretaceae), les feuilles de Combretum celastroides subsp. laxiflorum Welw (Combretaceae) et les écorces de tronc et de racines d'Hymenocardia acida Tul. (Euphorbiaceae). L'évaluation de l'effet vasorelaxant des extraits polaires issus de ces plantes sur les anneaux d’aorte isolée de rat a montré que les extraits testés ont un effet vasorelaxant endothélium-dépendant. Tous les extraits induisent cet effet via la voie du NO-GMPc alors que ceux de feuilles et d'écorces de racines de Combretum racemosum agissent également via la voie des prostanoïdes. Ces extraits ont aussi une action antioxydante. Enfin, l'administration chronique des extraits polaires de feuilles de Combretum celastroides subsp. laxiflorum et d'écorces de racines d'Hymenocardia acida aux rats spontanément hypertendus a montré que ces deux extraits possèdent une activité antihypertensive. Dans le but de déterminer les composés phytochimiques responsables de l’activité vasorelaxante observée, les extraits polaires de feuilles de Combretum celastroides subsp. laxiflorum et d'écorces de racines d'Hymenocardia acida ont été soumis à un fractionnement sur une colonne de polyamide. Toutes les fractions obtenues ont présenté une activité antioxydante, mais l'activité vasorelaxante était concentrée dans une fraction dont l'analyse par chromatographie liquide couplée à la spectrométrie de masse après thiolyse a indiqué qu'elle était enrichie en procyanidines. En conclusion, notre étude montre l'intérêt de ces plantes dans le traitement de l'hypertension en médecine traditionnelle congolaise, intérêt qui mérite d’être confirmé par des études cliniques rigoureuses./<p><p>Cardiovascular diseases represent a major cause of death in the world. Currently, their prevalence grows in sub-Saharan Africa where hypertension represents a major cardiovascular risk factor. Different drugs are used for the treatment of hypertension, but in low-income countries in general and in the D.R.Congo in particular, low socio-economic level forces the population to frequently recourse to the traditional health systems. In D.R.Congo, the traditional healers use a variety of plants to treat hypertension, but the pharmacological properties of some of these plants on vascular function have not been investigated.<p>To provide a scientific basis for the use of these plants in the treatment of hypertension in Congolese traditional medicine, we first carried out an ethnobotanical survey among traditional healers in some districts of Kinshasa and Bas-Congo, in the west of D.R. Congo, to obtain specific information about the plants that are used as antihypertensive remedies. As a result of this investigation, three plants were selected :leaves and root bark of Combretum racemosum P. Beauv (Combretaceae), leaves of Combretum celastroides subsp. laxiflorum Welw (Combretaceae), and trunk bark and root bark of Hymenocardia acida Tul. (Euphorbiaceae). The evaluation of the vasorelaxant effect of the polar extracts from these plants on isolated rat aorta showed that all extracts have an endothelium-dependent vasorelaxant effect. All extracts induce the vasorelaxant effect through the NO-cGMP pathway while those of Combretum racemosum leaves and root bark also act via the prostanoids pathway. These extracts also showed an antioxidant activity. Chronic administration of polar extracts of Combretum celastroides subsp. laxiflorum leaves and Hymenocardia acida root bark to spontaneously hypertensive rats showed that both extracts have an antihypertensive activity. Both extracts were fractionated on a column of polyamide in order to determine the nature of the compounds responsible for the vasorelaxant activity. All fractions obtained had an antioxidant activity but the vasorelaxant activity was concentrated in one fraction. Analysis of this fraction by liquid chromatography-mass spectrometry after thiolysis indicated that it was enriched in procyanidins. In conclusion, our study shows the interest of these plants in the treatment of hypertension in Congolese traditional medicine, interest which should be confirmed by rigorous clinical studies.<p> <p><br>Doctorat en Sciences biomédicales et pharmaceutiques<br>info:eu-repo/semantics/nonPublished

In this study, we sampled 11 populations including 94 individuals and completed the systematic of Clinopodium, the genetic diversity and phylogeography of C. laxiflorum from chloroplast DNA ( 2 non-coding region: atpB-rbcL, trnL-trnF), The chloroplast DNA atpB-rbcL non-coding region had 693 bp (base pair) after alignment, with 12 polymorphic sites, 0.00006 value of nucleotide diversity, 0.37 value of haplotype diversity. The chloroplast DNA trnL-trnF non-coding region had 281 bp (base pair) after alignment, with 14 polymorphic sites, 0.00226 value of nucleotide diversity, 0.55 value of haplotype diversity. Based on the analysis of 2 chloroplast DNA regions, the common haplotype of C. laxiflorum was distributed in most populations. Under neighbor-joining analysis, C. chinense was inner clade, and separated with C. laxiflorum obviously. Under genealogical analysis, there is closely relationship between haplotypes of C. chinense and C. laxiflorum. Estimating coalescent time, the differentiated time of C. chinense and C. laxiflorum was about 0.9~1.3 million years ago in the postglacial of Gunz (1.2~2.0 million years ago). Since the nucleotide diversity and haplotype diversity were in low level, it might be the bottleneck effect during the glacial period in the past.

Abstract:
碩士<br>國立嘉義大學<br>生物藥學研究所<br>95<br>Balanophora laxiflora Hemsley (Balanophoraceae), a parasitical plant, was used as folk medicine in Taiwan for chronic hepatitis treatment. The initial tentatively results demonstrated B. laxiflora contained polyphenolic constituents. with the previous research, polyphenolic compounds had well proved antioxidant activity. We first used methanol to extract the aerial part of B. laxiflora. The methanolic extract was dissolved in deionized water and partion with ethyl acetate and n-butanol sequentially. The antioxidative polyphenols were isolated from n-butanol layer of B. laxiflora by 1,1'-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical bioassay-guided scavenging model. Eleven polyphenolic compounds, 1,3-di-O-galloyl-4,6-hexahydroxydiphenoyl-b-D-glucopyranose (1), laxiflorin M1 (2), 1,3,4-tri-O-galloyl-b-D-glucopyranose (3), 3,4,6-tri-O-galloyl-b-D-glucopyranose (4), strictinin (5), balanophotannin C (6), 1-O-caffeoyl-6-O-galloyl-b-D-glucopyranose (7), 1-O-(E)-caffeoyl-4,6-(S)-hexahydroxydiphenoyl-b-D-glucopyranose (8), (-)-pinoresinol-O-b-D-glucopyranoside (9), 1,2,3,6-tetra-galloyl-b-D- glucopyranose (10), and (-)-isolariciresinol 4-O-b-D-glucopyranoside (11) were isolated from the aerial part of B. laxiflora. Laxiflorin M1 (IC50=1.79±0.09M) and 1,3,4-tri-O-galloyl-b-D-glucopyranose (IC50=1.70±0.10M) isolated from B. laxiflora showed strong DPPH radical scavenging activities compared with gallic acid, ascorbic acid, and caffeic acid as positive control (IC50=5.70±0.10, 21.67±0.06, and 12.93±0.07�嵱, respectively). On the other hand, 1-O-caffeoyl-6-O-galloyl-b-D-glucopyranose and 1-O-(E)-caffeoyl-4,6-(S)-hexahydroxydiphenoyl-��-D-glucopyranose with the caffeoyl group had ABTS．+ radical scavenging activity by supplying a electron to neutralize the free radical constituent. At present we found eleven pure compounds and one of them was a new compound. In carbon tetrachloride (CCl4)-induced liver cell injury assay, ICR mice were feed 250mg/kg and 500mg/kg dose of the buthanol layer extract of B. laxiflora for 7 days and had effective inhibitory in serum glutamic oxaloacetic transaminase (GOT, 222.00±10.39 U/L) and glutamic pyruvic transaminase (GPT, 236.67±39.12 U/L) compared with the control group without pretreated the extract (GOT = 279.83 ± 28.15 U/L, GPT = 398.67 ± 33.84 U/L). Owing to this property, we hoped through this study can be further extended to exploit not only the phenolic active extracts but also provide the medicinal associated substitute as health supplement.

Abstract:
碩士<br>國立中興大學<br>植物學系<br>86<br>Balanophora laxiflora Hemsl.(Balanophoraceae) is the holoparasitic plant on roots of the woody plants, and is widely distributed in middle altitudes overTaiwan. It has no ordinary roots, stems or leaves. It consists of a single or branching tubers and spicate, flesh inflorescence. Floral composition is verysimple, especially in female flowers which consist only of single ovaries. Theaim of this study is to understand the development of Balanophora laxiflora inflorescence, its reduction of floral organs, and to provide more informationfor other studies on Balanophoraceae plants. We used the techniques for SEM,paraffin and plastic sectioning to conduct the investigations. Balanophora laxiflora is a dioecious plant. Both male and female inflorescence primordia develop in the schizogenous cavity of the tuber. After most floralorgans have differentiated and becomes emerged, the inflorescence bud breaksthrough the epidermal layers of the tuber. All floral organs of the inflorescenceare acropetally initiated. In the male inflorescence, leaf-like bracts are initiated prior to male flower primordia or simultaneously, followed by tepal primordia andstamen primordia, orderly. Stamens have numerous connate anthers on the androeciumreceptacle, but no filaments. The anther wall only has epidermis and tapetum differentiated. Microsporogenesis is similar to that of common flowering plants. Based on the analysis of variances, the numbers of tepals and anthers are highly variable among individuals. In the female inflorescence, numerous spadicles are initated first. They areconsidered as reduced bracts ontogeneticly. The female flower primordia aremainly initiated on the inflorescence axis. Female flowers have no tepalsdeveloped but functional pistils. The ovary has one layer of ovary has onelayer of ovary wall and 2-3 layers of tapetum, but without a typically developedovule. However, the development of megaspore is monosporic type, which is similar as seen in most flowering plants. In summary, development of inflorescence in Balanophora laxiflora displaysno special differentiation of both sexes in a flower, stamen filament, andany floral organs but an overy in the female flower, and has no rudimentsexisted. Terefor such phenomena of losing floral organs might have occurredduring the early stage of evoluton.

It''s roots and the stems were once used as the agricultural pesticide. Taiwan aboriginals also took root''s juice to poison fish. The components can be used to poison fish, but innocuous to mammalian. The methanol extract from D. laxiflora was concentrated to give a residue which was partitioned between ethyl acetate and H2O. The ethyl acetate layer was separated by column chromatography on silica gel, preparative thin layer chromatography, flash column chromatography, and high performance liquid chromatography (HPLC) to give one hundred and forty three compounds, including 13 aromatic compounds, 5 chlorophylls, 25 flavonoids, 13 isoflavonoids, 12 lignans, 10 pterocarpans, 21 steroids, 32 triterpenoids, and 12 other type compounds. Known compounds were identified by IR, NMR, and Mass spectral analysis and comparison with those of authentic samples or data reported in literatures. Structures of new compounds were further elucidated by 2D NMR spectral and chemical methods. Among these isolated compounds, there are fifteen new compounds, and seven of them were isolated for the first time from natural sources.

Abstract:
碩士<br>國立臺灣大學<br>生態學與演化生物學研究所<br>101<br>Balanophora (Balanophoraceae) are holoparasitic, parasitizing on roots of host plants, obtaining water and nutrient from hosts with tuber-shaped haustoria. Flowers of Balanophora are highly reduced. There are only one whorl of tepals and a synandrium in the male flower. Female flower is reduced to only one extremely small pistil left for each flower. Balanophora laxiflora is a dioecious species, distributed in southern China, Vietnam, and Taiwan, growing under the forests at intermediate altitude. There have been many synonyms of B. laxiflora published through its taxonomic history, and there are also intraspecific variations in morphology and genetics within different populations. Morphology of female B. laxiflora is similar with that of B. japonica and B. yakushimensis. Recent study also confirmed that B. laxiflora is close to B. japonica and B. yakushimensis in phylogeny. There is no male individuals found for the later two taxa, and the agamospermy of B. japonica has been confirmed in previous studies. We speculated that B. japonica and B. yakushimensis were probably derived from B. laxiflora, being able to keep breeding and accumulating variation due to their agamospermic nature. This research increases the sampling of B. laxiflora individuals, using DNA molecular data to analyze the phylogenetic relationship within B. laxiflora and the two allied taxa. The aim of the study is to examine whether the allied taxa were derived from B. laxiflora, and if there is any cryptic taxa existing. Result of this study reveals that, in Taiwan, B. laxiflora, B. japonica and B. yakushimensis each forms a monophyletic group, and B. laxiflora is a sister group to the clade composed of the other two taxa. By analyzing the phylogenetic relationships with the chosen intraspecific genetic variation of B. laxiflora, a subset of populations form a highly supported monophyletic group. This group has all the characters as following: orange male inflorescence, horizontally elliptic male flower with eight or more tepals in the proximal flower region, and thin, narrow and orange to light yellow split bract lobes in male inflorescence. However, these are all continuous variations within B. laxiflora individuals. In Hansen’s monograph on Balanophora, host diversity of B. laxiflora is high. In the past, the main method to identify the host of Balanophora is tracing the root, which Balanophora parasitizes on, back to its plant trunk. The aim of this research is to identify the host plants that B. laxiflora parasitizes on to genus level by using DNA molecular data. According to the result, the confirmed hosts of B. laxiflora include Elatostema and Oreocnide (Urticaceae), Acer (Sapindaceae), Ficus and Morus (Moraceae), Alnus (Betulaceae), Rubus (Rosaceae), and Ardisia (Primulaceae). Different from B. laxiflora, B. japonica and B. yakushimensis show high host specificity to Symplocos (Symplocaceae) and Schima (Theaceae) respectively.

Two sesquiterpene polyol esters, celahin-D (26) and celahin-A (27); two triterpenes, loranthol (28) and friedelinol (29) were isolated from the stems of Celastrus hindsii. Among them, 6 and 26 are new compounds. 22-24 and 25 are isolated for the first time from Family Celastreaceae. The structures of these compounds were determined on the basis of spectral analysis. Biological evaluation showed that 22, 24 demonstrated cytotoxicity against Human colon carcinoma (colon-205, ED50 < 1.0 mg/ml).
