摘　　要：从昆明植物园栽培的南方常见的园艺植物雀舌黄杨 (BuxusbodinieriL啨ｖｌ .)中得到了 5个新甾体生物碱成分雀舌黄杨碱A -E (1- 5 ) ,通过波谱解析确定了化学结构。Five new steroidal alkaloids have been isolated from Buxus bodinieri Lévl.,a common ornamental in South-China. On the basis of IR, UV, MS, NMR spectral analyses and chemical evidence, the chemical structure of these new steroidal alkaloids were deduced as: buxbodine A (1)(20α- dimethylamino-9β,19-cyclo-4,4,14α-trimethy-5α-pregnane); buxbodine B (2)(16β-hydroxy-20α-dimethylamino-9β,19-cyclo-4,4,14α-trimethy-5α-pregn-1(2)-en-3-one); buxbodine C (3)(3β-dimethylamino-9β,19-cyclo-4,4,14α-trimethy-5α-pregn-6(7), 17 (20)-dien-16-one), buxbodine D (4)(3β-dimethylamino-20α-acetoxylamino-9β,19-cyclo -4,4,14α-trimethy-5α-pregn-6(7)-ene) and buxbodine E (5)(3(-dimethylamino-20α-amino -9β,19-cyclo-4,4,14α-trimethy-5α-pregn-6(7)-ene), respectively.
