Abstract

The invention discloses standard extracts in Inula salsoloides and an analytical method and application thereof. 16 compounds are isolated from Inula salsoloides, structures of the compounds are identified by the comprehensive use of modern spectroscopic techniques such as nuclear magnetic resonance spectroscopy, ultraviolet spectroscopy and mass spectroscopy, a new compound formula is C21H32O8, crystal color is white, and the new compound is named as II type eupatolide; activity studies discover that the compound IS-10 can repel the pests such as Phyllotreta striolata; the compounds IS-3 and IS-16 have antifeedant function, and it is proved that sesquiterpene compounds in Inula salsoloides are ingredients effective in providing pesticidal activity. The invention also discloses preparation and quantitative analytical method for standard extracts of Inula salsoloides, and activity testing discovers that the extracts have significant avoiding and antifeedant functions for the pests such as Phyllotreta striolata.

Description

technical field [0001] The present invention relates to an insect-repelling and insect-killing chemical active ingredient extracted from herbal medicine and its preparation and analysis method, in particular, it relates to the separation and activity of an insect-killing compound and a new compound in Salmonella inflorescence and its standardized insect-repelling and insecticidal composition Extract preparation and quantitative analysis methods. Background technique [0002] Convolvulus convolvulus is the flower and whole plant of Convolvulus convolvulus of the genus Convolvulus in the family Asteraceae.
