从柿( Diospyros kaki L.f.) 的果实中分离出 5 个化合物, 通过 IR、MS 、¹HNM R、¹³CNM R 鉴定, 确定为:熊果辛酯( octyl ursolate) , Δ^{5, 6}-3-( 2′-甲基戊酰氧基)-熊果酸环己酯〔Δ^{5, 6}-3-( 2′-methyl pentanoyl)-ursolic acid cy clohexyl ester〕, β-香
树脂醇己醚(β-amyrin hexyl ether) , Δ^{6, 7}-香树素( Δ6, 7-amyrin) 和熊果甲酯( methyl ursolate) 。
 

Five ursolate compounds from fruit of Diospyros kaki L.f .were isolated by MPLC .Identified by
means of spectral analysis ( IR, MS, ¹ HNMR, ¹³ CNMR) , they are :octyl ursolate, Δ^{5, 6}-3-( 2′-methyl
pentanoyl)-ursolic acid cyclohexyl ester, β-amyrin hexyl ether, Δ^{6, 7}-amyrin and methyl ursolate .
