摘要:

为探明蜂王浆中的植物甾醇组成,蜂王浆样品经冻干、萃取得到王浆脂类物质,再经过皂化、衍生后使用HP-5MS 柱进行分离,采用GC-MS 对蜂王浆中甾醇类物质进行鉴定,并用GC-FID 内标法进行定量分析。结果表明:蜂王浆中除含有少量胆固醇外,还含有25- 羟基-24- 甲基胆甾醇、菜油甾醇、豆甾醇、β - 谷甾醇、Δ5-燕麦甾醇、Δ7- 燕麦甾醇等植物甾醇;蜂王浆中总甾醇含量在51mg/100g 鲜王浆以上。其中,25- 羟基-24- 甲基胆甾醇、菜油甾醇、β- 谷甾醇和Δ5- 燕麦甾醇含量较高,分别占总甾醇含量的36.79%、6.30%、19.75% 和27.99%。

Abstract:

To figure out the sterol composition of royal jelly, royal jelly samples were lyophilized and extracted and the extracted lipid substances were then saponified, derivatized and separated on a HP-5MS column prior to gas chromatography with flame ionization detection (GC-FID ) coupled with mass spectrometric identification of sterols, and quantitative analysis was finally conducted by internal standard method. A small amount of cholesterols was contained in royal jelly, and the main sterols were 25-hydroxy-24-methylcholesterol, campesterol, stigmasterol, β-sitosterol, Δ5-avenasterol and Δ7-avenasterol. The total content of sterols in 100 g of fresh royal jelly was higher than 51 mg. Among these sterols, the most predominant components were 25-hydroxy-24-methylcholesterol, campesterol, β-sitosterol and Δ5-avenasterol, accounting for 36.79%, 6.30%, 19.75% and 27.99%, respectively.
