Four previously undescribed iridoid glycosides, including two bis-iridoid glycosides, and three undescribed lignans, together with 16 known analogues, were isolated from the fruits of Gardenia jasminoides Eills. Their structures were elucidated on basis of spectroscopic methods, and the absolute configurations of three of the unknown compounds were determined by interpretation of their electronic circular
从栀子的果实中分离出四种先前未描述的环烯醚萜苷,包括两种双环烯醚萜苷和三种未描述的木脂素,以及 16 种已知的类似物。基于光谱方法阐明了它们的结构,并通过解释它们的电子圆二色性 (ECD) 和 [α] 来确定三种未知化合物的绝对构型20D数据。的α葡萄糖苷酶的分离的化合物的抑制效果进行了评价,所有的化合物与IC的值显示出略微抑制活性50大于50 μ M.
