Abstract

Two flavonol diglycosides, tamarixetin 3-O-neohesperidoside, kaempferide 3-O-neohesperidoside and the known quercetin 3-O-neohesperidoside, together with six other known flavonoids were isolated from the leaves of Costus spicatus and their structures were elucidated by a combination of spectroscopic and chemical methods. The flavonol diglycosides were evaluated for inhibitory activity of nitric oxide production by activated macrophages (Fig. 1).

摘要

从皱叶闭鞘姜的叶子中分离出两种黄酮醇二糖苷，即 tamarixetin 3-O-新橙皮糖苷、山柰酚 3-O-新橙皮糖苷以及已知的槲皮素 3-O-新橙皮糖苷，还有其他六种已知黄酮类化合物，并通过光谱和化学方法相结合的方式阐明了它们的结构。对这些黄酮醇二糖苷进行了活性巨噬细胞产生一氧化氮抑制活性的评估（图 1）。
