Chemical constituents from Mallotus furetianus / 中草药

ABSTRACT

Objective To study the chemical constituents of Mallotus furetianus. Methods The constituents were isolated and purified by silica gel chromatography and HPLC repeatedly, and the structures were identified by spectra analysis and chemical methods. Results Sixteen compounds were isolated from the leaves of M. furetianus, the structures were identified as 3-hydroxy-4,5 (R)-dimethy1-2 (5H)-furanone (1), gallic acid (2), 3,4,8,9,10-pentahydroxydibenzo [b, d] pyran-6-one (3), epicatechin (4), catechin (5), kaempferol-3-O-robinobioside (6), apigenin (7), 2-hydroxysuccinic acid (8), 5-hydroxymethylfuroic acid (9), gallic acid methyl ester (10), caffeic acid (11), tanshinol (12), diolmycin B2 (13), oresbiusin A (14), 3,4-dihydroxyphenyl-β- D-glucopyranoside (15), and (2S)-pyroglutamic acid (16). Conclusion Compounds 7-16 are obtained from the genus of Mallotus for the first time, and compounds 4-16 are obtained from M. furetianus for the first time.
