为研究某些植物油的抗生育作用,作者将槟榔(Areca catechu)的果实、番木瓜(Carica papaya)果肉、亚州扁担杆(Grewia asiatica)的种子、胡萝卜(Daucus carota)的种子、蓖麻(Ricinus Communis)的种子分别以石油醚(60～80℃)提取,提取液减压浓缩至除尽石油醚,得到的油经活性炭、漂白土纯化后用阿拉伯胶制备成不同剂量的混悬液,于雌性大鼠妊娠的第一天到第七天,口服给药,进行抗生育作 In order to study the anti-fertility effects of certain vegetable oils, the authors used the fruit of Areca catechu, Carica papaya pulp, seeds of Grewia asiatica, seeds of Daucus carota, and ramie ( The seeds of Ricinus Communis were extracted with petroleum ether (60-80 DEG C), and the extract was concentrated under reduced pressure until the petroleum ether was removed. The obtained oil was purified through activated carbon and bleaching earth and then was prepared into different suspensions using gum arabic. On the first day to the seventh day of pregnancy in female rats, oral administration was conducted for anti-fertility
