Six New Triterpene Derivatives from Aralia chinensis Var. dasyphylloides
AbstractAralia chinensis var. dasyphylloides is widely distributed in China and used as a traditional herbal medicine for the treatment of digestive and immune system diseases. The present study aimed to search for novel oleanolic-type triterpenoids in low-polarity fractions. Six new triterpene derivatives (1–6), together with two known compounds were isolated from the barks of A. chinensis var. dasyphylloides. Their structures were elucidated by 1D- and 2D-NMR spectroscopic analysis and chemical methods. They were identified as 3-oxo-oleana-11,13(18)-dien-28,30-dioic acid (1), 30-hydroxy-3-oxo-oleana-11,13(18)-dien-28-oic acid (2), 3β-hydroxy-oleana-11,13(18)-dien-28-oic acid-28-O-β-d-glucopyranoside (3), 3β,30-dihydroxy-oleana-11,13(18)-dien-28-oic acid-28-O-β-d-glucopyranoside (4), 3β-hydroxy-oleana-11,13(18)-dien-28-oic acid-3-O-β-d-xylopyranosyl-(1 → 2)-β-d-glucopyranoside (5), 3β,29-dihydroxy-oleana-9(11),12-dien-28-oic acid-28-O-β-d-glucopyranoside (6), namely, araliachinolic acids I and II and araliachinosides I–IV. The cytotoxicity of the isolated compounds was tested against HepG2, A549, SGC7901, and MCF7 cell lines, but no apparent activity was observed at a concentration of 50 μM. View Full-Text
