Abstract:
OBJECTIVETo isolate and elucidate the constituents from stem of Chirita longgangensis var. hongyao.
METHODThe constituents were extracted with methanol and isolated by chromatography on silica gel, Sephadex LH-20 and ODS. The structures were determined by NMR and MS spectral analysis.
RESULTFive phenylethanoid glycosides were identified as 3, 4-dihydroxyphenyl alcohol-beta-D-glucopyranoside (1), 3, 4-dihydroxyphenyl alcohol-6-O-caffeoyl--D-glucopyranoside (calceolarioside B) (2), 3, 4-dihydroxyphenyl alcohol-beta-D-glucopyranosyl-(1 --> 3)-6-O-caffeoyl-beta-D-glucopyranoside (plantainoside D) (3), 3, 4-dihydroxyphenyl alcohol-beta-D-glucopyranosyl-(1 --> 3)-4-O-caffeoyl-beta-D-glucopyranoside (plantamajoside) (4), 3, 4-dihydroxyphenyl alcohol-beta-D-glucopyranosyl-(1 --> 3)-6-O-feruloyl-beta-D-glucopyranoside (scroside E) (5), respectively.
CONCLUSIONCompounds 3 and 5 were isolated for the first time from the family Gesneriaceae, and compounds 1, 2 and 4 were isolated for the first time from the genus Chirita.
