竹笋被认为是甾醇的潜在来源。利用超高效液相色谱-大气压化学电离质谱联用技术，研究了竹笋中甾醇含量和组成的遗传变异性、部位和采收季节对竹笋甾醇含量和组成的影响。结果表明：竹笋中具有代表性的甾醇为β-谷甾醇、菜油甾醇、豆甾醇、麦角甾醇、胆固醇和豆甾烷醇;除豆甾烷醇外，不同种的甾醇含量差异显著（112.4-279.6mg/100 g干重），不同收获季节（195.3- 279.6 mg/100 g干重）和不同部位甾醇的含量在不同种类和不同采收季节间基本相同，但茎体和茎壳中的甾醇含量存在显著差异。遗传变异性、部位和收获季节对竹笋中甾醇成分有显着影响。毛竹春笋壳中甾醇含量最高，为321.8mg/100 g干重。
Bamboo shoots are regarded as potential sources of sterols. The effects of genetic variability, parts and harvest seasons on the sterol content and composition in the bamboo shoots have been determined using a novel ultra-performance liquid chromatographic atmospheric pressure chemical ionisation mass spectrometer method. The results showed that the representative sterols in bamboo shoots were β-sitosterol, campesterol, stigmasterol, ergosterol, cholesterol and stigmastanol; exception stigmastanol, the significant differences were observed in the sterol content of different species (112.4–279.6mg/100g dry wt), different harvest seasons (195.3–279.6mg/100g dry wt) and different parts (253.6–321.8mg/100g dry wt); the sterol composition was similar in different species and different harvest seasons, however, it was significantly different between shoot bodies and shoot shell. The genetic variability, parts and harvest seasons could significantly affect the sterol composition in the bamboo shoots. The spring shoot shell of Phyllostachys pubescens contained the highest sterol content (321.8mg/100g dry wt).
