Chemical constitutents in the fruits of Gardenia jasminoides var. radicans Makino / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the chemical constituents in the fruits of Gardenia jasminoides var. radicans Makino. METHODS: Percolation with alcohol and liquid-liquid extraction methods were used to extract the constituents. And silica gel, reverse-phase octadecylsilyl(ODS), and sephadex LH-20 chromatographic methods were applied to isolate and purify compounds. MS, NMR spectroscopic methods were used to elucidate their structures. RESULTS: Ten compounds were isolated from the ethyl acetate fraction of the ethanolic extract of fruits from Gardenia jasminoides var. radicans Makino, and their structures were identified as seven iridoids geniposide (1), 6α-hydrogeniposide (2), 6β-hydrogeniposide (3), 6α-methoxygeniposide (4), 6β-methoxygeniposide (5), 2'-O-(4″-Hydrooxycinnamoyl) mussaenosidic acid(6), 6″-O-trans-p-coumaroylgenipin genitiobioside(7); two quinic acid derivatives 3, 5-di-O-caffeoyl-4-O-(3-hydroxyl-3-methyl) glutaroylquinic acid(8), methyl 3, 5-di-caffeoyl-4-O-(3-hydroxy-3-methyl)-glutaroylquinate(9); and one flavonoid quercetin-3-O-β-D-glucopyranoside(10). CONCLUSION: Compounds 3-10 are isolated from Gardenia jasminoides var. radicans Makino for the first time.
