杠柳杀虫活性成分的分离
Isolation of the insecticidal ingredients from Periploca sepium
摘要
Abstract
Two compounds, periplocoside D and F were isolated from the methanol extract of the root barks of Periploca sepium by silica gel chromatograph, high pressure liquid chromatograph( HPLC) and bioassay-guided fractionation. The bioassay results showed that periplocoside D and F had stomach toxic activity with the LC50 value of 48 h 0. 39 and 0. 34 mg/mL against 3rd instar larvae of Mythimna separata,and against 3rd instar larvae of Plutella xyllostella with the LC50 value of 48 h 1.21 and 1.39 mg/mL.关键词
