Chemical constituents from the stem of Embelia laeta

doi:10.5246/jcps.2022.04.023

Abstract

Abstract:

In the present study, we aimed to investigate the chemical constituents from Embelia laeta. The constituents were separated by various column chromatography, including silica gel, ODS gel, MCI gel, Sephadex LH-20, and semipreparative HPLC. Their structures were elucidated by spectroscopic means. A total of 13 compounds were isolated from E. laeta and identified as (6R,9R)-1-Oxo-α-ionol-9-O-β-D-goucopyranoside (1), (+)-Pinoresinol (2), Leptolepisol D (3), Kaempferol (4), Kaempferol-3-α-L-Ramnopyranoside (5), Kaempferol-3-β-D-(6-O-trans-p-coumaroyl) glucopyranoside (6), Bis(2-ethylhexyl) phthalate (7), 2-Benzenedicarboxylic diisobutyl ester (8), Caffeic acid methyl ester (9), Paldehyde (10), Coniferaldehyde (11), Caffeic acid (12) and 5-Hydroxymethyl furfural (13), respectively. All the compounds were isolated from E. laeta for the first time.
