GC/MS和HPLC对陈皮“陈久者良”的验证

Validity test of parlance "Pericarpium Citri Reticulatae, the older the better" by GC/MS and HPLC

目的采用色谱分析对陈皮“陈久者良”的说法进行验证。方法用GC/MS和HPLC/DAD联用技术,对不同年份自贡陈皮和“老化”模拟实验新会陈皮样品的挥发油和黄酮类成分进行分析。结果新鲜和陈旧的陈皮样品的挥发油,各低沸点成分随时间延长均有下降,而较高沸点成分下降缓慢;黄酮类物质无明显变化。结论高含量柠檬烯使新鲜果皮气味不佳,陈皮则柠檬烯逐渐减少,气味随之香醇。对陈皮“陈久者良”的说法找到了一定根据。

OBJECTIVE: To test the validity of parlance, 'Pericarpium Citri Reticulatae(PCR), the older the better'. METHODS: The volatile components and flavonoids in PCR samples were determined by GC/MS and HPLC/DAD. Four samples from Zigong in Sichuan province had been deposited for 0,4,7 year and and 10 years, respectively. The others from Xinhui in Guangdong provence were roasted for 0, 1.2,4,6,8,16 h and 32 h at 80 °C. RESULTS: The constituents of volatile oils with lower boiling points reduced remarkably, but constituents with higher boil reduced little. Flavonoids didn't have obvious changes between fresh and old samples. CONCLUSION: The parlance, 'Pericarpium citri Reticulatae, the older the better', is reasonable to some extent.
