Abstract:
Objective: To isolate and identify the chemical constituents in the ethanol extract from the barks of Illicium brevistylum. Methods: The barks of I. brevistylum were extracted by 80% ethanol then partitioned by system solvents with different polarity. The ethyl acetate extract was separated on silica gel, Sephadex LH-20, and ODS columns. The isolated compounds were identified by physicochemical properties and spectral analyses. Results: Twelve compounds were isolated and purified from the ethyl acetate extract of I. brevistylum and the structures were identified as quercetin 3-O-β-xylopyranoside (1), quercetin (2), dihydro kaempferol (3), kaempferol (4), wulingzhic acid V (5), catechin (6), 3, 5, 7-trihydroxylchromone-3-O-α-L-arabinopyranoside (7), majucin (8), anislactone B (9), 7-O-acetylanislactone B (10), dunnianolide C (11), and taxifolin-3-O-β-xylopyranoside (12). Conclusion: Compounds 5 and 7 are obtained from the plants in Illiciaceae for the first time and compounds 1, 6, and 8-11 are firstly isolated from I. brevistylum.
