目的研究暖胃舒乐片挥发油中的化学成分。方法采用《中华人民共和国药典》2010年版一部挥发油测定法对暖胃舒乐片的挥发油进行提取,用气相色谱-质谱法对化学成分进行鉴定,以毛细管柱进行分析,面积归一化法测定其相对含量。结果检出51种成分,鉴定其中45种,占总流出峰面积的95.1%。相对含量>5%的成分有棕榈酸(55.80%)和十六烷酸乙酯(11.81%)。结论暖胃舒乐片中挥发油成分主要包含酸类和酯类。
Objective To study the chemical composition of nourishing stomach Shule piece volatile oil. Methods A volatile oil was used to determine the volatile oil in Weweish Shule tablets. The chemical constituents were identified by gas chromatography-mass spectrometry (GC-MS) and analyzed by capillary column. The area normalization method Its relative content. As a result, 51 species were detected and 45 species were identified, accounting for 95.1% of the total outflow peak area. Palmitic acid (55.80%) and hexadecanoic acid ethyl ester (11.81%) were used in the relative content> 5%. Conclusion The components of the volatile oil in Weishu Shule tablets mainly contain acids and esters.
