摘要
Abstract
Objective:To study the differences of essential oil's component extracted from 3 different chemical-types Perilla leaves with different maturity at different stages,and confirm the harvest method suitable for every chemical-type of Perilla frutescens.Methods:This paper researched on PK,PA and PL chemotype germplasms of P.frutescens.The samples were the different maturity leaves collected in nutrition,flowering and frutescence periods.The volatile oilwas extractedby steam distillationand analyzed by GC-MS.Results:From the view of volatile oil yield,three kinds of chemotype showed very different.In flowering and frutescence periods,the tender leaves of PA type had high yield,contrariwise themature leaves of PK type and the old mature leaves of PL type had high yield.In nutrition period,PA type mature leaves had high yield,but PK type and PL type tender leaves had the highest.From the view of relative content of main component,perillaldehyde,perillaketone and perillene,characteristic constituents in three chemotypes,in nutrition and frutescence periods,the contents of tender leaves were the lowest,while the mature leaves were the lowest in flowering period.Conclusion:According to the volatile oil yield and relative content of maincomponents,for PA type,mature leaves should be harvested in the early stage of flowering period;for the PK type mature leaves should be harvested in all period and old mature leaves in frutescence period;for the PL typemature leaves and old mature leaves should be harvested in the nutrition period.关键词
