Generic delimitations among the Asian members of the Persea group, including the recently described genus Alseodaphnopsis, are discussed. These genera, with the exception of Alseodaphnopsis, are characterized by reproductive characters. A study of flowers of Alseodaphnopsis species found that Alseodaphnopsis species have unisexual flowers and that Alseodaphnopsis is better defined by its unisexual flowers than by vegetative characters. This is the first report of the presence of unisexual flowers in any member of the Persea group.

Lauraceae is a large family of woody plants with high ecological and economic value. The tribal and generic division and phylogenetic relationship of Lauraceae have long been controversial. Based on morphological and molecular evidence, phylogenetic relationships within the Cinnamomeae, Laureae and Perseeae tribes, also called ‘the Core Lauraceae’, have arisen particular attention. In this review, we comprehensively collated the literatures on the phylogeny of Lauraceae published in recent years and summarized progress made in molecular systematic researches employing gene fragments, chloroplast genomes and DNA barcodings analyses. We clarified the phylogenetic relationships and main controversies of ‘the Core Lauraceae’, the systemic position of fuzzy genera (Neocinnamomum, Caryodaphnopsis and Cassytha) and the development of chloroplast genome and DNA barcodes. We further suggested and proposed the whole genome analysis and different inflorescence types would be possible to provide more information for further research on phylogenetic relationships and taxonomy of Lauraceae.

Keluarga Medang-medangan (Famili Lauraceae) merupakan salah satu kelompok tumbuhan yang banyak ditemukan di daerah tropis. Lauraceae juga termasuk kelompok yang paling banyak dimanfaatkan dan bernilai ekonomi tinggi. Pemanfaatan intensif dan nilai ekonomi yang tinggi tidak diimbangi dengan usaha konservasi yang memadai membuat Famili Lauraceae menjadi rentan dalam kepunahan. Permasalahan yang muncul dari keinginan untuk melakukan konservasi bagi Famili Lauraceae adalah sangat minimnya pengetahuan tentang jenis serta nama ilmiah yang benar. Taman Hutan Kota Muhammad Sabki merupakan hutan kota yang diperlukan karena fungsinya antara lain memperbaiki dan menjaga iklim mikro dan nilai estetika, meresapkan air, menciptakan kesimbangan dan keserasian lingkungan fisik kota, dan mendukung pelestarian keanekaragaman hayati di Indonesia. Peneliti tertarik untuk melakukan eksplorasi botani dan identifikasi terhadap keanekaragaman jenis famili Lauraceae yang berada di taman hutan kota Muhammad Sabki. Penelitian dilakukan ada bulan Agustus-Oktober 2017 di taman Hutan Kota M. Sabki. Kesimpulan yang dapat diambil dari penelitian ini adalah anggota family Lauraceae di Hutan Kota M. Sabki ditemukan berjumlah 12 spesies dengan indeks keanekaragaman Shannon-Wiener 2,36.

AbstractThe Lauraceae family is predominantly found in Asia and in the rainforests of the Americas, and consists mostly of aromatic trees. Being an essential oil producer, this family is used in the food, pharmaceutical, and cosmetic industries. This work presents a systematic review of the chemical composition and bioactivity of the essential oils from the Lauraceae family. Medline, Scielo, Web of Science, Lilacs, and Scopus were employed to identify articles published between 2000 and 2018, using “Lauraceae”, “essential oil”, and “biological activity” as key words. From 177 studies identified, 53 met the inclusion criteria. These studies indicated a predominance of the compounds β-caryophyllene and 1,8-cineole in Lauraceae species, and highlighted the antioxidant, antifungal, antibacterial, and anti-inflammatory activities. Essential oils extracted from this family thus have high potential for pharmacological applications.

AbstractAlseodaphneis a genus of timber trees (ca. 40 spp.) belonging to thePerseagroup of the Lauraceae. It is widely distributed in tropical Asia, but is often confused withDehaasiaandNothaphoebe, and the systematics of the genus is unclear. Here, the complete chloroplast genome sequences ofA. semecarpifoliawill be reported, the type species ofAlseodaphne, and two China-endemic species,A. gracilisandA. huanglianshanensis. The three plastomes were 153 051 bp, 153 099 bp and 153 070 bp, respectively. Comparative genomic analyses indicate that the threeAlseodaphneplastomes have similar genome size and those are very different with previously published plastomes of Lauraceae in length. The length difference is directly caused by inverted repeats expansion/contraction. Four highly variable loci includingpsbD-trnM,ndhF-rpl32,rpl32-trnLandycf1among the threeAlseodaphnespecies were identified as useful plastid candidate barcodes forAlseodaphneand Lauraceae species. Phylogenetic analyses based on 12 complete plastomes of Lauraceae species confirm a monophyleticPerseagroup comprising species ofAlseodaphne,Phoebe,PerseaandMachilus.

Bogor Botanic Gardens (BBG) is an ex-situ plant conservation area with thousands of plant collections. The trees of the Lauraceae in BBG experienced the highest number of deaths among other families. However most of them were categorized as young planting years (0-15 years). A tree health monitoring in the Lauraceae needs to be conducted to provide an overview, trend, and value of the level of damage. Forest Health Monitoring (FHM) method was carried out on two plots consisting of 149 trees. FHM can identify the types and levels of damage through monitoring and recording a series of tree damage. The results showed that among 149 trees, with 103 healthy, 9 lightly damaged, 10 moderately damaged, 15 heavily damaged, and 12 dead. The damage was primarily found in the stem (63 trees), the crown branch (51 trees), and the roots (13 trees). The severity of the damage was mainly at a mild level (0-19%). The cause of the damage is discussed. Further observations and frequent monitoring of the health of the Lauraceae need to be conducted by management to reduce the number of dead collections of the family.

Besides recruitment and dispersal, fruits are key resources for the maintenance of insect communities. This study is focused on the insects inhabiting the fruits of 4 wild Lauraceae species. Although the trees of this family are important elements of tropical forests, their interaction with insects, especially in association with fruits, remains poorly studied in wild tree species. Our study aims to characterize the diversity of insects associated with fruits of Damburneya ambigens, Damburneya gentlei, Damburneya salicifolia, and Nectandra turbacensis, in the rainforest of Los Tuxtlas, Veracruz. We present an illustrated taxonomic list of species, annotated with a comprehensive review of the insects’ natural history and their interactions with Lauraceae species. We reared 54 insect species from approximately 6,500 fruits, some of which represent potential new species and records for Mexico. Insect species diversity was high and differed between Lauraceae species. The reared insects comprise a wide variety of distributional ranges, feeding types, and habitats. This research provides novel information about the interactions among insects and fruits of Lauraceae and the complexity of their trophic networks in tropical rainforests. Furthermore, it evidences the importance of wild fruits as resources for insect communities.

A Floresta Ombrófila Mista desempenha importante função social e ecológica na região Sul do Brasil. Embora tenha sofrido um profundo processo exploratório, resultando em sua fragmentação, apresenta elevado potencial para o manejo que, devidamente aplicado, favorece a conservação e recuperação de seus remanescentes. Com o objetivo de avaliar o incremento diamétrico e a dinâmica sucessional dessa fitofisionomia, foram empregados dados oriundos do estrato arbóreo (DAP ≥9,5 cm) de 10 parcelas permanentes de 1 ha cada, remedidas anualmente entre o período de 2000 a 2009, na Floresta Nacional de São Francisco de Paula, RS. As observações e projeções indicaram gradual redução da densidade da floresta, com destaque para a espécie Araucaria angustifolia (Bertol.) Kuntz., entretanto, observou-se tendência de aumento na densidade da família Lauraceae. O período de meia vida estimado para a floresta foi de 97 anos e, para Araucaria angustifolia, 332 anos. As estimativas ainda sugerem que, em 71 anos, as espécies de Lauraceae devem duplicar sua densidade. O crescimento da floresta foi inferior ao da família Lauraceae (= 0,175 cm/ano e = 0,179 cm/ano, respectivamente) e a Araucaria angustifolia manteve o menor crescimento (= 0,159 cm/ano). As análises indicaram um avanço sucessional, com a gradual substituição da Araucaria angustifolia por espécies com maior adaptação às condições de equilíbrio.Palavras-chave: Família Lauraceae; Floresta com Araucária; sucessão florestal. AbstractEcology and diametric projection of three arboreal groups in a Mixed Ombrophilous Forest fragment in São Francisco de RS, Brazil. The Mixed Ombrophylous Forest performs an important social and ecological function in southern Brazil. Although it has suffered a profound exploratory process, resulting in their fragmentation, it has a high potential for management that, properly applied, promotes conservation and recovery of their remains. In order to assess the increment in diameter and dynamics of phytophisiognomy, this research used data from the tree strata (DBH≥9.5 cm) of 10 permanent plots of 1 ha each remeasured annually between the period 2000 to 2009 in São Francisco de Paula National Forest, RS, Brazil. The observations and projections indicate a gradual reduction in the forest density, showing up Araucaria angustifolia (Bertol.) Kuntze species, however, for the Lauraceae species, there was a tendency of increase. The period of half-life estimated for the forest was 97 years and for Araucaria angustifolia, 332 years. The estimates also suggested that in 71 years, the Lauraceae should double its density. The forest growth was lower than that observed in the Lauraceae (=0.175 cm/year and =0.179 cm/year, respectively) and Araucaria angustifolia maintained the lowest growth (=0.159 cm/year). The analysis indicated a positive advance, with the gradual replacement of Araucaria angustifolia by other species with greater adaptation to the successional conditions. Keywords: Araucaria Forest; Lauraceae family; forest succession.

Ocotea bilocellata Baitello, D.B.O.S.Cardoso & P.L.R.Moraes, a species of Lauraceae that is new to science and from the Atlantic rain forest of the state of São Paulo, Brazil, is described and illustrated. The newly described species does not fit in any of the traditionally circumscribed disporangiate Lauraceae genera; rather, we show that it is phylogenetically placed within the Ocotea minarum group, as revealed by nuclear ribosomal ITS and plastid psbA–trnH sequence data.

Litsea Lam. is an ecological and economic important genus of the “core Lauraceae” group in the Lauraceae. The few studies to date on the comparative chloroplast genomics and phylogenomics of Litsea have been conducted as part of other studies on the Lauraceae. Here, we sequenced the whole chloroplast genome sequence of Litsea auriculata, an endangered tree endemic to eastern China, and compared this with previously published chloroplast genome sequences of 11 other Litsea species. The chloroplast genomes of the 12 Litsea species ranged from 152,132 (L. szemaois) to 154,011 bp (L. garrettii) and exhibited a typical quadripartite structure with conserved genome arrangement and content, with length variations in the inverted repeat regions (IRs). No codon usage preferences were detected within the 30 codons used in the chloroplast genomes, indicating a conserved evolution model for the genus. Ten intergenic spacers (psbE–petL, trnH–psbA, petA–psbJ, ndhF–rpl32, ycf4–cemA, rpl32–trnL, ndhG–ndhI, psbC–trnS, trnE–trnT, and psbM–trnD) and five protein coding genes (ndhD, matK, ccsA, ycf1, and ndhF) were identified as divergence hotspot regions and DNA barcodes of Litsea species. In total, 876 chloroplast microsatellites were located within the 12 chloroplast genomes. Phylogenetic analyses conducted using the 51 additional complete chloroplast genomes of “core Lauraceae” species demonstrated that the 12 Litsea species grouped into four sub-clades within the Laurus-Neolitsea clade, and that Litsea is polyphyletic and closely related to the genera Lindera and Laurus. Our phylogeny strongly supported the monophyly of the following three clades (Laurus–Neolitsea, Cinnamomum–Ocotea, and Machilus–Persea) among the above investigated “core Lauraceae” species. Overall, our study highlighted the taxonomic utility of chloroplast genomes in Litsea, and the genetic markers identified here will facilitate future studies on the evolution, conservation, population genetics, and phylogeography of L. auriculata and other Litsea species.

The diversity of secondary metabolites of individual plants results from multiple enzymatic processes in planta and various environmental factors, such as temperature, moisture, and soil conditions. Chemical composition analysis of plants can lead to a new method to understand relationship among comparable plants along with biological classification such as genetic and anatomical method. In this study, the chemical diversity of nine different Lauraceae species was investigated, and the plant samples were chemically analyzed and classified. Multivariate analysis methods, such as PLS-DA, were used to select important metabolites distinguishing the nine Lauraceae species. The selected metabolites were identified through preparative LC-MS or MS/MS fragment pattern analysis. In addition, the chemical dendrogram for the nine Lauraceae species was interpreted through molecular network analysis and compared with the genetic dendrogram. This approach enabled us to compare the complete chemical compositions of multiple plant samples to identify relationships among plants.

Methanolic leaf extracts of four Lauraceae species endemic to Laurisilva forest (Apollonias barbujana, Laurus novocanariensis, Ocotea foetens and Persea indica) were investigated for the first time for their potential to inhibit key enzymes linked to type-2 diabetes (α-amylase, α-glucosidase, aldose reductase) and obesity (pancreatic lipase), and protein glycation. Lauraceae extracts revealed significant inhibitory activities in all assays, altough with different ability between species. In general, P. indica showed the most promissing results. In the protein glycation assay, all analysed extracts displayed a stronger effect than a reference compound: aminoguanidine (AMG). The in vitro anti-diabetic, anti-obesity and anti-glycation activities of analysed extracts showed correlation with their flavonols and flavan-3-ols (in particular, proanthocyanins) contents. These Lauraceae species have the capacity to assist in adjuvant therapy of type-2 diabetes and associated complications, through modulation of the activity of key metabolic enzymes and prevention of advanced glycation end-products (AGEs) formation.

Cryptocarya (Lauraceae), yang dikenal dengan nama daerah “medang” merupakan salah satu kelompok tumbuhan endemik hutan tropik Indonesia. Kelompok tumbuhan ini secara fitokimia merupakan penghasil metabolit sekunder golongan alkaloid, α-piron, flavonoid dan triterpen. Berkaitan dengan hal tersebut di atas, kajian fitokimia terhadap senyawa alkaloid dari spesies Cryptocarya tawaensis Merr (Lauraceae) belum pernah dilaporkan sebelumnya. Hasil penelitian terhadap spesies ini telah berhasil diisolasi dan diidentifikasi dua senyawa turunan alkaloid aporfin, yaitu N-metillaurotetanin (1) dan boldin (2), dimana struktur molekul kedua senyawa tersebut ditetapkan berdasarkan sifat fisika, data spektroskopi UV, IR, 1H-NMR dan serta perbandingan dengan data senyawa standar yang telah dilaporkan. Senyawa 1 pernah dilaporkan sebelumnya dari spesies C. longifolia, sementara senyawa 2 baru pertama kali ditemukan dalam tumbuhan Cryptocarya. Berdasarkan penemuan kedua senyawa tersebut, dapat disimpulkan bahwa C. tawaensis dapat dikelompokkan ke dalam tumbuhan Cryptocarya penghasil alkaloid.
