Chemical Constituents of the Fruits of Gardenia jasminoides form.grandiflora (Lour.) Makino.

对茜草科植物大花栀子果实进行化学成分研究,分离得到8个化合物。经理化数据对照和波谱分析,鉴定化合物的结构为:(4R)-4-羟基-2,6,6-三甲基-1-环己烯-1-甲酸(1)、西红花酸(2)、西红花苷-4(3)、西红花苷-3(4)、西红花苷-2(5)、西红花苷-1(6)、京尼平苷(7)和京尼平-1-β-D-龙胆二糖苷(8)。经检索,其中化合物2～6为首次从该植物中分离得到。

The chemical constituents of the fruits of Gardenia jasminoides form. grandiflora （ Lour. ） Makino. were studied. Eight compounds were isolated and their structures were elucidated by comparison of their physico chemical properties and spectral data with those of reference data. The compounds were determined to be （4R） -4-hydroxy-2,6,6-trimethyl-1 -cyclohexene-1 -carbexylic acid （ 1 ）, crocetin （2）, crocin-4 （3）, crocin-3 （4）, crocin-2 （5）, crocin-1 （6） , geniposide （7） and genipin-1 -β-D-gentiobioside （8）, respectively. Among them, compounds 2-6 were obtained from this plant for the first time.
