    Journal: Zhong Yao Cai; 2008 Feb; 31(2):219-21. PubMed ID: 18619264.
    Abstract:
    OBJECTIVE: To study the chemical constituents of Arachniodes exilis. METHODS: The methanolic extract was isolated and purified by silica gel, C18 reverse phase silica gel and Sepadex LH-20 gel column chromatography. The chemical structures were elucidated on the basis of the physicochemical properties and spectral data. RESULTS: Eight phenolic compounds were obtained and identified as aspidin-BB (I), 4-methyl-2-butyl-3,5-dihydroxyphenol (II ), eriodictyol (III), epicatechin (IV), procyanidin B2 (V), miscathoside (VI), eriodictyol-7-O-beta-D-glucopyranuronide (VII), luteolin-4'-O-beta-D-glucopyranuronide (VIII), respectively. CONCLUSION: Compounds II-VIII are obtained from this plant for the first time.
