Abstract
OBJECTIVE
To study chemical constituents of Ardisia punctata,in order to find pioneering compounds.
METHODS
95% ethanol extracts of A. punctata was separated and purified by using normal phase silica gel column chromatographies, Sephadex LH-20 gel column chromatography and high-pressure preparative HPLC,and their structures were identified by such spectroscopic techniques as NMR and MS.
RESULTS
Eight compounds were separated from 95% ethanol extract of A. punctata and identified as 6-methoxy-8-hydroxy-benzoic acid butylester-5-O-beta-D-glucoside (1), aridisiacrispin B (2), ardisicrenoside A (3), dibutyl phthalate (4), bergenin (5), quercetin-3-O-alpha-L-rhamnoside (6),3-methoxy-4-acetoxy-6-tridecyl-phenol(7) and belamcandaquinone C(8).
CONCLUSIONS
Compound 1 was a new compound, and compounds 4 and 6 were separated from this plant for the first time.
