components from the hexane extract of dried flower buds of Egletes viscosa were identified by gas chromatography-mass spectrometry as trans-carvyl acetate, cis-carvyl acetate, sabinyl acetate, verbenyl acetate, cyclopentaethylidene, geranyl acetate and 5-methylfuranone, and trans-pinocarvyl acetate (major component). From the non-volatile residue, centipedic acid and a novel clerodane diterpene, 12-acetoxy-hawtriwaic
用气相色谱-质谱联用技术鉴定了Egletes viscosa干燥花蕾己烷提取物中的蒸汽挥发性成分为反式香芹酯、顺式香芹酯、乙酸槭酯、乙酸马鞭草酯、环戊二烯、乙酸香叶酯和5-甲基呋喃酮,以及反式松香醋酸酯(主要成分)。从非挥发性残留物中分离出蜈蚣酸和新型克罗丹二萜、12-乙酰氧基-hawtriwaic 酸内酯。从乙醇提取物中分离出 ternatin(4',5-dihidroxy-3,3',7,8-四甲氧基黄酮)。Ternatin 具有抗炎、保肝和保护胃的特性,并且根据 NCI 协议,它对 HIV 显示出中等活性。二萜表现出解痉活性。
