Two novel bibenzyl trigonopols A (1) and B (2), together with seven known compounds, gigantol (3), tristin (4), moscatin (5), hircinol (6), naringenin (7), 3-(4-hydroxy-3-methoxyphenyl)-2-propen-1-ol (8), and ( − )-syringaresinol (9), have been isolated from the stems of Dendrobium trigonopus, of which compounds 6, 8, and 9 were isolated for the first time from this species. The structures of two new compounds were elucidated as threo-22-(17-hydroxyl-9-(3-hydroxyl-4-methoxy-phenethyl)-13,16,18-trimethoxy-21H-benzo[c]chromen-21-yl)ethane-22, 23-diol (1) and 9-(4-hydroxyl-3-methoxy-phenethyl)-17-(21-hydroxyl-20-methoxy-phenyl)chroman-11, 16-diol (2) on the basis of spectroscopic methods. Trigonopol A was found to exhibit antiplatelet aggregation activity in vitro with 67.55% inhibitory ration at 1.4337 × 10− 3 M.

Journal of Asian Natural Products Research

《亚洲天然产物研究杂志》（JANPR）以英语出版亚洲民族医学天然产物研究领域的化学和药物研究。该杂志发表亚洲国家科学家的工作，例如。中国、日本、韩国和印度，包括其他国家对亚洲天然产品的贡献。该杂志以化学为导向。涵盖的主要领域有：天然成分（包括非医疗用途）的分离和结构阐明、天然产物的合成和转化（包括生物合成和生物转化）、生药学和相关主题。粗提物的生物学评估仅可作为具有良好表征结构的纯分离物的支持数据。本期刊中所有发表的研究文章都经过了严格的同行评审，基于初始编辑筛选和至少两名专家评审的匿名评审。

The Journal of Asian Natural Products Research publishes in English and focuses on the chemistry and pharmacology of natural products in Asian ethnomedicine. The journal features research from scientists in Asian countries such as China, Japan, South Korea, and India, as well as contributions from other countries regarding Asian natural products. The main areas of coverage include the isolation and structural elucidation of natural compounds, the synthesis and transformation of natural products (including biosynthesis and biotransformation), pharmacognosy, and related topics. Biological evaluations of crude extracts are only considered as supporting data for well-characterized pure isolates. All research articles published in this journal undergo rigorous peer review, which includes initial editorial screening and anonymous reviews by at least two experts.
