在埃及栽培的黑种草种子的物理化学性质进行了测定。还通过两种不同的方法对从种子中提取的原油进行了物理和化学分析。结果表明，黑种草子是一种良好的油脂和蛋白质来源。不同的提取方法不仅影响出油率，而且影响原油的理化性质。TLC和GLC分析表明，黑种草子油含有大量的甾醇。亚油酸（C-18：2）、油酸（C-18：1）和棕榈酸（C-16：0），如大多数常见食用油中一样，是主要的脂肪酸。这种油富含β-谷甾醇，可以抑制膳食胆固醇的吸收。(C)2003年由Elsevier Ltd.出版
Physico-chemical properties of nigella seeds cultivated in Egypt were determined. Physical and chemical analyses of crude oils extracted from the seeds, by two different methods were also performed. The results revealed that nigella seed is a good source for oil and protein. Percentage of oil extraction, as well as physical and chemical properties of the crude oil, was influenced by the extraction methods. TLC and GLC analysis indicated that nigella seed oil contained significant amounts of sterols. Linoleic (C-18:2), oleic (C-18:1) and palmitic (C-16:0), as in most of the common edible oils, are the main fatty acids. The oil was rich in beta-sitosterol that inhibits the absorption of dietary cholesterol. (C) 2003 Published by Elsevier Ltd.
