Seven 4-desmethylsterols, five triterpene alcohols and three 4α-monomethylsterols were identified by GC-MS during the development of wild peanut, which is Arbi (AraA), and cultivars peanut, which are Trabelsia (AraT) and Chounfakhi (AraC). Our results showed that the maximum level of 4-desmethylsterols (881.07 mg/100 g of oil) was reached at 12 days after flowering (DAF) date of peanut plant in AraA, as well as the highest level of triterpene alcohols (31.51 mg/100 g of oil) was reached at 23 DAF in AraA, whilst, the highest level of 4α-monomethylsterols (15.11 mg/100 g of oil) was reached at 41 DAF in AraC. Herein, the level of triterpene alcohols and 4α-monomethylsterols was overwhelmed by the amount of 4-desmethylsterols at each stage of peanut maturity. Differences were observed in each sterol contents among the studied cultivars and wild one especially in immature stage.
在野生花生（Arbi，AraA）和栽培花生（Trabelsia，AraT 和 Chounfakhi，AraC）的发育过程中，通过 GC-MS 鉴定出了七种 4-去甲基甾醇、五种三萜醇和三种 4α-单甲基甾醇。我们的研究结果表明，在 AraA 中，花生植株开花后 12 天（DAF）达到 4-去甲基甾醇的最高水平（881.07mg/100g 油），在 AraA 中达到三萜醇的最高水平（31.51mg/100g 油）23 DAF，而 AraC 中 4α-单甲基甾醇的最高水平（15.11mg/100g 油）在 41 DAF 达到。在此，在花生成熟的每个阶段，三萜醇和 4α-单甲基甾醇的水平都被 4-去甲基甾醇的数量所超越。在所研究的品种和野生品种中，每个甾醇的含量存在差异，特别是在不成熟阶段。
