Abstract:
AbstractSubmerged cultures of the edible mushrooms Phlebopus portentosus and Phlebopus spongiosus were screened for their secondary metabolites by HPLC-UV/Vis and HR-LC-ESI-MS. Two new compounds, 9′-hydroxyphenyl pulvinone (1), containing an unusual pulvinone structure, and phlebopyron (2), together with the seven known pigments, atromentic acid (3), xerocomic acid (4), variegatic acid (5), methyl atromentate (6), methyl isoxerocomate (7), methyl variegatate (8), and variegatorubin (9) were isolated from the cultures. Their structures were assigned on the basis of extensive 1D/2D NMR spectrosc

Abstract:
Berberis species have been used extensively as raw material in various herbal medicines. In this work, a fast and sensitive method based on reversed-phase high-performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (HPLC-ESI-QTOF-MS/MS) was used to assist the distribution and discrimination study of bioactive compounds from Berberis species such as B. aristata, B. asiatica, B. chitria, B. jaeschkeana, B. koehneana, B. lyceum, B. petiolaris and B. pseudoumbellata. The HPLC separation was performed on a Thermo Betasil C8 column (

Abstract:
Noscapine, a phthalideisoquinoline alkaloid derived from opium, has been used in the treatment of various cancer types. Its low-toxicity profile has increased attention to this alkaloid. With regard to increasing demand for this compound, we developed a new method for isolation of noscapine from dried capsules ofPapaver somniferum. Noscapine was successfully isolated from poppy capsules for the first time and the purity of the isolated compound was determined to be over 99.59% by HPLC analysis. The structure of noscapine was confirmed by NMR, NMR, FT-IR, elemental analysis, and HR-ESI-MS metho

Abstract:
Two new prenylated flavanones, isomaackiaflavanone A (1), isomaackiaflavanone B (2) and a new prenylated stilbene maackiastilbene (3), along with five known flavanones were isolated from the root bark of Maackia amurensis using repeated column chromatography on silica gel, Sephadex LH-20 and octadecyl silica (ODS-A) sorbents. The structures of the new compounds were elucidated by HPLC–PDA–MS, HR-ESI-MS, 1H, 13C, 1H–1H COSY, HSQC, ROESY and HMBC NMR analyses. The cytotoxicity of compounds 1–2, 4–8 against two human cancer cell lines HeLa and SK-MEL-5 was tested using the MTS method. Compounds 4

Abstract:
Echinochrome A (Ech A, 1) is one of the main pigments of several sea urchin species and is registered in the Russian pharmacopeia as an active drug substance (Histochrome®), used in the fields of cardiology and ophthalmology. In this study, Ech A degradation products formed during oxidation by O2 in air-equilibrated aqueous solutions were identified, isolated, and structurally characterized. An HPLC method coupled with diode-array detection (DAD) and mass spectrometry (MS) was developed and validated to monitor the Ech A degradation process and identify the appearing compounds.

Abstract:
Dalbergia odorifera T. Chen, as an important traditional Chinese medicinal plant, has been used in China over a long history. The chemical composition of volatile oil extracted from the D. odorifera flowers is described for the first time here. The volatile oil was extracted by hydro-distillation, and GC-MS was used for the chemical composition analysis. Tectorigenin, an isoflavonoid, was also isolated from the flowers. The structure of tectorigenin was established based on 1H and 13C NMR and HR-ESI-MS spectrometry. The main components of the volatile oil from the flowers were 4-hydroxy-4-meth

Members of genus Xenorhabdus are symbiotically associated with entomopathogenic nematodes of genus Steinernema. Herein, we describe the isolation and purification of four novel metabolites, xenocyloins G-J (1–4), from liquid cultures of Xenorhabdus bovienii SN52 by extensive column chromatography and semi-preparative HPLC. Chemical structures of the xenocyloin derivatives were determined based on comprehensive NMR spectra and HR-ESI-MS analyses. All compounds exhibited significant collagen-induced anti-platelet aggregation activities, among which xenocyloin H (2) exhibited the strongest activi

L'analyse de la composition chimique de deux orchidées de la sous-tribu des Aeridinae, Aerides rosea Lodd. ex. Lindl. & Paxton et Acampe rigida (Buch.-Ham. ex Sm.) P. F.

Dix dérivés phénanthréniques ont ainsi été identifiés dans les tiges d'A. rosea, dont deux nouvellement décrits. Quatre stilbénoïdes, trois dérivés d'acides phénoliques et quatre esters d'acide cinnamique ont été identifiés dans les tiges d'A. rigida.
