Chemical constituents of leaves of Lindera aggregate (sims)kosterm / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the chemical constituents of the leaves of Lindera aggregata. METHODS: Various column chromatographic techniques were used to separate and purify the chemical constituents and their structures were elucidated by spectral analysis. RESULTS: Twelve compounds were isolated and identified as hydroxylindestrenolide (I), linderalactone (II), pseudone-olinderane(III), quercetin-3-O-α-L-rhamnoside(IV), kaempferol-3-O-α-L-arabinofuranoside(V), kaempferol-3-O-β-D-galactopyrano-side(VI), kaempferol-3-O-β-D-xylopyranoside (VII), quercetin-3-O-(2″-O-β-D-glucopyranosyl) -α-L-arabinofuranoside (VII), querce-tin-3-O-(2″-O-β-Z)-glucx)pyranosyl) -β-D-xylopyranoside(IX), syringoside (X), acantrifoside E(XI), 2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside(XII). CONCLUSION: The compounds VI-XII were isolated from Lindera genus for the first time.
