摘　　要：目的:研究头状蓼的脂肪酸成分。方法:采用索氏提取法提取脂肪酸成分,用气相色谱-质谱法分析化学成分。结果:从头状蓼中分离鉴定了17个脂肪酸成分,3个甾醇类成分和植醇,占色谱总出峰面积的67.22%,主要成分为亚麻酸,亚油酸和棕榈酸。结论:头状蓼中脂肪酸主要为不饱和脂肪酸,含量较高的亚麻酸、亚油酸和棕榈酸可能是头状蓼的药效成分之一。Objective： To analyze the fatty acids from polygonum alatum Buch. -Ham. Methods： The fatty acids were extracted by Soxhlet extraction, and GC-MS was used to analyze their chemical components. Results： Seventeen fatty acids compounds, three sterols and one phytol were identified from p. alarum Buch. -Ham., amounting to 67.22% of the total constituents, linolenic acid, linoleic acid and palmic acid were the main compounds. Conclusion： Unsaturated fatty acids are the main compounds of P. alatum Buch. -Ham.. linolenic acid, linoleic acid and palmic acid which may be the efficacy components of P. alatum Buch. -Ham..
