对在两种不同贮存温度下经不同贮存期的药用春黄菊进行比较。将取自三种花期的一个二倍体和两个四倍体基因型样本蒸馏,测定其比重,从而鉴定其精油成分。药用春黄菊精油损耗的主要原因是贮存温度较高及开花成熟期过长。在温度为16℃,相对湿度为60％的条件下贮存31个月后,大花头春黄菊基因型样本仅存54％的精油原成分,中等 Comparison of medicinal chamomile at different storage periods at two different storage temperatures. One diploid and two tetraploid genotype samples from three flowering periods were distilled and their specific gravity was determined to identify their essential oil components. The main reason for the loss of medicinal chamomile essential oil is the storage temperature is high and the flowering maturity is too long. After 31 months of storage at a temperature of 16 ° C and a relative humidity of 60%, only a 54%
