A new minor polyoxygenated triterpene named glutinolic acid (1) and two new aeginetic acid quinovosides (2, 3) were isolated from the roots of Rehmannia glutinosa LIBOSCH. (Scrophulariaceae) cultivated in Gunwi-gun, Korea. The structures of these compounds were established as 3α,19α,20β,24,30-pentahydroxyurs-12-en-28-oic acid (1, glutinolic acid), aeginetic acid 5-O-β-D-quinovoside (2) and aeginetoyl
从地黄的生根中分离出一种新的次要多氧化三萜,即谷氨酸(1)和两个新的庚酸奎奴糖苷(2、3)。(玄参科)在韩国群威郡种植。这些化合物的结构确定为3α,19α,20β,24,30-五羟基urs-12-en-28-oic酸(1,谷氨酸),庚酸5-O-β-D-喹诺酮苷(2)和在化学和光谱学证据的基础上,形成了5”-O-β-D-喹诺酮苷类的Aeginetoyl Ajugol(3)。
