对西藏牦牛和湖北黄牛的背最长肌（LSM）、股二头肌（BFM）、肝脏（LV）、皮下脂肪组织（SAT）和腹部脂肪组织（AAT）5个部位的生物活性成分进行了研究。牦牛显著较高（p 0.05）。牦牛的总生育酚含量显著高于黄牛（p<0.05）。牦牛肝脏脂肪中饱和脂肪酸含量最高（58.11%），多不饱和脂肪酸含量最高（25.81%），单不饱和脂肪酸含量最低（16.08%）;黄牛肝脏脂肪中单不饱和脂肪酸含量最高（47.54%），多不饱和脂肪酸含量最低（2.36%）。两者在组成上的显著差异表明牦牛的五种组织是人体生物活性成分和必需脂肪酸的潜在来源。
实际应用：通过对西藏牦牛和湖北黄牛不同组织中角鲨烯、生育酚、总脂、水分、灰分、pH值和脂肪酸组成的分析，为以牦牛肉或其他组织为原料开发功能性食品提供了依据。
牦牛和黄牛不同组织中角鲨烯和总生育酚含量的比较。
Bioactive components in five tisues (longissimus muscle (LSM), biceps femoris muscle (BFM), liver (LV), subcutaneous adipose tissue (SAT), and abdominal adipose tissue (AAT)) of yak in Tibet and yellow cattle in Hubei were investigated. Yak was significantly higher (p 0.05). Yak was also significantly higher (p<0.05) than yellow cattle in the total tocopherol content. Additionally, yak hepatic lipids showed the highest content of saturated fatty acids (58.11%) and polyunsaturated fatty acids (PUFA, 25.81%) and the lowest content of monounsaturated fatty acids (MUFA, 16.08%), while yellow cattle AAT had the highest content of MUFA (47.54%) and the lowest content of PUFA (2.36%). The considerable differences between the two in composition suggest that the five tissues of yak are potential sources of bioactive components and essential fatty acids for humans.
Practical applications: The results from the analysis of the contents of squalene, tocopherols, total lipids，moisture, ash, and pH and fatty acid profile in the studied tissues of Tibet yak and Hubei yellow cattle provide useful information for developing functional foods using yak meat or other tissues as materials.
