    The chemical composition of compounds in Lepidium sativum seeds, sourced from two different origins and extracted using two non-polar solvents, and analyzed using GC/MS
    (Napata College, 2024-08) Gamalat Ahmed Osman; Hatil Hashim EL-Kamali
    The objective of this research was to explore the compounds present in the n-hexane and petroleum ether extracts of Lepidium sativum seeds obtained from two different sources (Sudan and Saudi Arabia) using Gas Chromatography–Mass Spectroscopy (GC/MS) technique. The qualitative and quantitative analysis of the samples was carried out using Gas Chromatography/Mass Spectrometry (GC/MS). The major constituents identified in the n-hexane extract of the Sudan sample were cisvaccenic acid (17.03%), 9-octadecenamide, (Z)- (13.03%), gamma-sitosterol (10.14%), betatocopherol (7.845%), o-cymene (4.30%), and 9-octadecenoic acid, 1,2,3-propanetriyl ester (4.091%). The major phytochemical constituents identified in the petroleum ether extract of the Sudan sample were gamma-sitosterol (14.09%), beta-tocopherol (12.10%), 9-octadecenoic acid, methyl ester (11.82%), 9,12-octadecadienoic acid (Z,Z), methyl ester (8.40%), and tributyl acetyl citrate (8.26%). The major phytochemical constituents identified in the n-hexane extract of the Saudi sample were gamma-sitosterol (13.38%), beta-tocopherol (10.92%), 4-fluorobenzaldehyde (6.26%), octadecanoic acid (6.21%), butylphosonic acid, di(4-octyl) ester (6.17%), and campesterol (6.00%). The major phytochemical constituents identified in the petroleum ether extract of the Saudi sample were gammaterpinene (26.86%), o-cymene (25.52%), thymol (12.76%), beta-tocopherol (6.88%), beta-pinene (6.01%), and gamma-sitosterol (5.73%).
