摘　　要：从旱莲草Ｅｃｌｉｐｔａａｌｂａ全草中分得一个新的三萜皂甙成分，命名为旱莲甙Ｃ（ｅｃｌｉｐｔａｓａｐｏｎｉｎＧ），根据理化性质和光谱数据，阐明了它的化学结构。另外还分得胡萝卜甙，豆甾醇－３－氧葡萄糖甙，β－谷甾醇和硬脂酸，其中胡萝卜甙和豆甾醇－３－氧葡萄甙为首次从鳢肠属植物中获得．Ecliptasaponin C(1), a new triterpenoid glucoside. was isolated together with daucosterol (2) and stig-masterol-3-O-glucoside (3) from Eclipta alba. Based on spectral analysis, chemical evidence and hydrolytic results. it's structure was deduced as 3-β-Oβ-D-glucopyranosy 1-19 β-hydroxy olean-12-ene-28-oic acid 28-O-β-D-glucopyranoside,Compounds 2 and 3 were obtained from Eclipta for the fist time.
