中文摘要：

将瘤背石磺（Onchidium struma）、里氏拟石磺（Paraoncidium reevesii）、平疣桑椹石磺（Platevindex mortoni）和紫色疣石磺（Peronia verruculata）样品,经活体解剖取四种石磺肌肉组织,运用高效液相色谱法对其可食部分进行了胆甾醇含量测定。结果表明：瘤背石磺胆甾醇平均浓度最高,达5870.00 mg/kg；平疣桑椹石磺、紫色疣石磺、里氏拟石磺的胆甾醇平均质量分别为3480.00、388.00、316.00 mg/kg,统计分析显示四种石磺可食部分的胆甾醇含量差异显著。

英文摘要：

In this paper, the contents of cholesterol in four species of Onchidiidae include Onchidium struma , Paraoncidium reevesii, Platevindex mortoni and Peronia verruculata were determined by high performance liquid chromatography （HPLC）. The results show that the average cholesterol content of O. Struma, P. Mortoni, P. Verruculata and P. reevesii was 5 870.00 mg/kg, 3 480.00 mg/kg, 388.00 mg/kg and 316.00 mg/kg, respectively. Statistical analysis shows that the content of cholesterol in the edible part of four species has significant difference.
