A new octadecatrienoic acid and a new benzyl glycoside, along with a known compound, were isolated from the leaves of Smallanthus sonchifolius. The structures of the two new compounds were elucidated as 13(R)-hydroxy-octadeca-(9E,11E,15Z)-trienoic acid (1) and benzyl alcohol 7-O-alpha-L-arabinopyranosyl(1" --> 2')-beta-D-glucopyranoside (2) on the basis of spectroscopic analysis and chemical evidence. The known compound was identified as 13(R)-hydroxy-octadeca-(9Z,11E,15Z)-trienoic acid (3) by comparison of its spectral data with that reported. Compound 3 was isolated for the first time from the title plant.
从小叶山薯的叶子中分离出一种新的十八碳三烯酸和一种新的苄基糖苷,以及一种已知化合物。基于光谱分析和化学证据,将这两种新化合物的结构鉴定为13(R)-羟基-十八碳-(9E,11E,15Z)-三烯酸(1)和苄醇7-O-α-L-阿拉伯吡喃糖基(1"→2')-β-D-吡喃葡萄糖苷(2)。通过将其光谱数据与报道的数据进行比较,将已知化合物鉴定为13(R)-羟基-十八碳-(9Z,11E,15Z)-三烯酸(3)。化合物3首次从标题植物中分离得到。
