Plant Sterol and stanol esterified currently applied in foods that can produce lowering of the serum cholesterol level.

植物甾醇一般是以甾醇酯的形式应用于食品中：含有植物酯化甾醇或甾烷醇的食物能够使血清胆固醇水平降低。

Phytosterols are a group of components naturally occurring in all plants and are structurally similar to cholesterol. Until now, numerous unique phytosterols have been identified, p-sitosterol, campesterol, and stigmasterol account for the largest proportion in most sources, and the saturated phytosterol are called "phytostanol", such as sitostanol and campestanol.

植物甾醇是存在于植物中的一大类化学物质的总称，其结构与胆固醇相似，几乎存在于所有的植物性食物中，最常见的包括β-谷甾醇、菜油甾醇、豆甾醇，其次是植物甾醇的饱和形式，即β-谷甾烷醇和菜油甾烷醇等。

The optimal conditions were as follows: molar ratio of lauric acid to phytosterols 1.4:1, reaction temperature 120℃, SDS 1.5% and reaction time 4 hours. Under this condition, the yield of esterification reached 87.9%. After three steps of purification the content of phytosterol ester is about 93.1%. The product was determined as phytosterol laurate with FT-IR.
