首次从藏药“生等”，即鼠李科猫乳属植物西藏猫乳Rhamnellagilgitica的干燥心材中分离并鉴定了9个黄酮体化合物，分别是墨沙酮（maesopsin，Ⅰ），香橙素（aromadendrin，Ⅱ），柚皮素（naringenin，Ⅲ），山柰酚（kaempferol，Ⅳ），懈皮素（quercetin，Ⅴ），花旗松素（taxifolin，Ⅵ），顺-4，6，4’-三羟基异噢［（z）-4，6，4’-trihydroxyaurone，Ⅶ］，4，6，4’-三羟基异噢（4，6，4’-trihydroxyisoaurone，Ⅷ），山柰酚-7-O-β-D-葡萄糖甙（kaempferol-7-O-β-D-glucoside，Ⅸ）．其中化合物Ⅰ为主要成分，得率0．41％；化合物Ⅷ为首次从天然界获得。 For the first time, 9 flavonoid compounds were isolated and identified from the dried heartwood of the Tibetan medicine “Shengyue et al.”, a genus of the cat genus Rhamnella giltica. The flavonoid compounds were mesosone (I) and orange ( Aromadendrin, II), naringenin (III), kaempferol (IV), quercetin (V), taxifolin (VI), cis-4,6,4’- Trihydroxyisoindole [(z)-4,6,4’-trihydroxyaurone,VII],4,6,4’-trihydroxyisoaurone (VIII), kaempferol-7 -O-β-D-glucoside (kaempferol-7-O-β-D-glucoside, IX). Among them, compound I is the main component with a yield of 0.41%; compound VIII is obtained from natural world for the first time.
