L. (Family Poaceae) is cultivated in tropical regions as a staple food all over the world. The rice grain husk is considered as a tonic and administered orally to relieve dysentery. The air-dried seeds husks of were exhaustively extracted with methanol in a Soxhlet apparatus. The concentrated methanol extract was adsorbed on silica gel and chromatographed on a silica gel column. The column was eluted with petroleum ether, chloroform and methanol successively to isolate four phytoconstituents characterised as 7-ketostigmasterol (), 3β-benzyloxy-stigmast-7-one-22-en-19-oic acid 29-ethyleneglycol ether (), sesquaurs-11-en- 2β, 3β,5α-triol () and 2'-(1''β-hydroxypropyl)-7,4'-dimethoxyapigenin (). These phytoconstituents were identified on the basis of spectral data analysis.
（禾本科）在热带地区被广泛种植，作为全世界的主食。稻谷的外壳被认为是一种滋补品，可口服治疗痢疾。将 的风干种子外壳用甲醇在索氏提取器中进行了充分提取。浓缩的甲醇提取物被吸附在硅胶上，并在硅胶柱上进行色谱分离。用石油醚、氯仿和甲醇依次洗脱柱，分离出四个植物成分，分别鉴定为 7-酮豆甾醇（）、3β-苯甲氧基-豆甾-7-酮-22-烯-19-酸 29-乙二缩乙二醇醚（）、倍半萜-11-烯-2β,3β,5α-三醇（）和 2'-(1''β-羟基丙基)-7,4'-二甲氧基芹菜素（）。这些植物成分是基于光谱数据分析鉴定的。
