A new diterpenoid glucoside, (3S,5S,6S,8R,9R,10S)-3,6,9-trihydroxy-13(14)-labdean-16,15-olide 3-O-β-D-glucopyranoside (1), and a new iridoid glucoside, (1S, 5S,6R,9R)-10-O-p-hydroxybenzoyl-5,6β-dihydroxy iridoid 1-O-β-D-glucopyranoside (2), along with six known compounds (3-8) were isolated from Vitex trifolia L.. Their structures were elucidated by extensive spectroscopic analysis. All these isolated compounds were evaluated for their inhibitory effects on nitric oxide production in LPS-induced RAW 264.7 macrophages. Compounds 2, 4, 5, and 7 showed moderate inhibitory activities with IC values of 90.05, 88.51, 87.26, and 76.06 μM, respectively.
从三叶荆芥（Vitex trifolia L.）中分离得到了一个新的二萜苷类化合物（3S,5S,6S,8R,9R,10S）-3,6,9-三羟基-13(14)-labdean-16,15-内酯 3-O-β-D-吡喃葡萄糖苷（1）和一个新的环烯醚萜苷类化合物（1S, 5S,6R,9R）-10-O-对羟基苯甲酰基-5,6β-二羟基环烯醚萜 1-O-β-D-吡喃葡萄糖苷（2），以及另外 6 个已知化合物（3-8）。通过广泛的光谱分析确定了它们的结构。所有这些分离得到的化合物都被评估了对 LPS 诱导的 RAW 264.7 巨噬细胞中一氧化氮产生的抑制作用。化合物 2、4、5 和 7 表现出中等抑制活性，IC 值分别为 90.05、88.51、87.26 和 76.06 μM。
