摘要
从糙苏Phlomis umbrosa全草的脂溶性部位共分得16个化合物,分别鉴定为: 1-Ο-b-葡萄 糖-2-O-顺-二十碳烯-9-酸-甘油酯(I),甘油酸甘油三酯(Ⅱ),齐墩果酸(Ⅲ),马斯里酸(Ⅳ),熊果 酸(V),2a-羟基-熊果酸(Ⅵ),3a-羟基-熊果酸(Ⅶ),β-谷甾醇葡萄糖苷(Ⅷ),2,6-二聚果糖(Ⅹ),D- 果糖(Ⅹ),D-吡喃葡萄糖(ⅩⅠ),豆甾醇(ⅩⅡ),β-谷甾醇(ⅩⅢ),油酸(ⅩⅣ),亚油酸(ⅩⅤ),月桂酸 (Ⅵ)。其中化合物 Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅵ、Ⅶ、Ⅸ、ⅩⅡ系首次从该植物中分得。化合物Ⅰ为一新的天然产 物。它们的结构经波谱分析和化学转化等方法确定。
From the Chinese medicinal plant Phlomis umbrosa Turcz., 16 compounds were isolated and identified by various spectral analysis and chemical conversion, as 1-O-gluco-2-O-gadoleic-glyceride (Ⅰ), trilinolein (Ⅱ), oleanolic acid (Ⅲ), maslinic acid (Ⅳ), ursolic acid (Ⅴ), 2a-hydroxyl--ursolic acid (Ⅵ ), 3a-hydroxyl-ursolic acid (Ⅶ), β-sitosterol glucopyranoside (Ⅷ), 2, 6-difructose (Ⅸ), D-fructose (Ⅹ), D--glucose (Ⅺ ), stigmasterol (Ⅻ ), β-sitosterol (ⅩⅢ), oleic acid (ⅩⅣ), linoleic acid (ⅩⅤ)and lauric acid (ⅩⅥ). Among them, compounds Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅵ,Ⅶ,Ⅸ,Ⅻ were discovered in this plant for the first time and compound I was a new natural product.
