摘要(Abstract)：
从三裂叶蟛蜞菊全草甲醇提取物中分离得到1个新的化合物——蒲公英烷-14-烯-30-醛-3β-棕榈酸酯(1),以及6个已知化合物,分别鉴定为对映-贝壳杉-16-烯-19-酸(2)、16α-羟基-对映-贝壳杉烷-19-酸(3)、蒲公英赛醇(4)、β-香树脂醇(5)、1β-乙酰氧基-4α,9α-二羟基-6β-异戊酰氧基卤地菊内酯(6)、豆甾醇(7)。化合物结构结合红外、核磁、高分辨质谱等现代波谱技术进行鉴定。
A new taraxer-based triterpenoid ester, taraxer-14-en-30-al-3β-O-palmitate(1), was isolated from the whole plant of Wedelia trilobata, along with six known compounds, ent-kaur-16-en-19-oic acid(2), 16α-hydroxy-ent-kauran-19-oic acid(3), tara-xerol(4), β-amyrin(5), 1β-acetoxy-4α, 9α-dihydroxy-6β-isobutyroxyprostatolide(6), and stigmasterol(7). Their structures were elucidated with use of a combination of spectroscopic techniques(IR, HR-ESI-MS, 1 D, 2 D NMR data) and chemical methods.
