摘要:

从中药泽泻[Alisma orientalis (Sam.)Juzep.]抑制尿草酸钙结石形成的活性部位分离得到3个化合物, 并鉴定为alisol F 24-acetate、alisol A 24-acetate和alismoxide. 首次应用1H-1H COSY、HMQC和HMBC 等2D NMR技术对alisol F 24-acetate的氢信号进行全归属.

关键词: 2D NMR, 泽泻, alisol F 24-acetate, 草酸钙结石, 活性成分

Abstract:

Three compounds were isolated from the active fraction of Alisma orientalis (Sam.) Juze extract that inhibits urinary oxalate calcium calculi formation, and identified to be alisol F 24-acetate, alisol A 24-acetate and alismoxide. The proton chemical shifts of alisol F 24-acetate were assigned by using 2D NMR techniques including 1H-1H COSY、HMQC and HMBC.

Key words: 2D NMR, Alisma orientalis(Sam.)Juzep, alisol F 24-acetate, oxalate calcium calculi
