为寻找植物源农药活性成分,研究了肋果茶茎叶的化学成分,从其乙醇提取物的乙酸乙酯部分分离了7个化合物,通过MS、NMR等谱学手段鉴定它们的结构为3α,3′,4′,5,7-五羟基黄烷醇(Ⅰ)、3β,3′,4′,5,7-五羟基黄烷醇(Ⅱ)、3β,4′,5,7-四羟基黄烷醇(Ⅲ)、熊果酸(Ⅳ)、山楂酸(Ⅴ)、22E,24R-麦角甾烷-7,22-二烯-3α-O-D-葡萄糖苷(Ⅵ)以及12-齐墩果烷-3,22,24-三醇-3β-O--L-阿拉伯糖苷(Ⅶ).3个黄烷醇类化合物Ⅰ、Ⅱ和Ⅲ为首次从该属植物中分到.加. From the leaf and stem parts of Sladenia celastrifolia Lurz, seven compounds, 3α,3′, 4′, 5,7Pentahydroxyflavan (Ⅰ), 3β,3′,4′,5,7Pentahydroxyflavan (Ⅱ), 3β,4′,5,7Tetrahydroxyflavan (Ⅲ), Ursolic acid (Ⅳ), Maslinic acid (Ⅴ), 22E,24Rergosta7,22dien3αODGlucopyranoside (Ⅵ), and 12Oleanene3,22,24triol3βOLArabinopyranoside (Ⅶ), were isolated. Their structures were identified by physicochemical properties and spectral analysis. Three flavanol compoundsⅠ,Ⅱ,and Ⅲ were isolated from the genus for the first time.
