摘要

The essential oils of the flower-buds,leaves and stems of Filipendula palmata(Pall.)Maxim,were analyzed by GC and GC-MS.Thirty-three,forty-seven and forty-seven compounds in the flower-buds,leaves and stems were identified,respectively.Methyl salicylate exists in a great amount which is up to 70.10% in the flower-buds.Its amount is also high in other two parts.The data obtained show that it may be one of the main natural mosquito-expelling and pain-alleviating components in the three parts.The flower-buds are the main active part with the mosquito-expelling function.
