Quassin compound as well as preparation method and application thereof

Abstract

The invention discloses quassin compounds as well as a preparation method and application thereof. The quassin compounds are a series of compounds which are separated from stems and / or branches and leaves of picrasma quassidioides (D.Don) Benn) which is a picrasma quassidioides plant. Tests show that the compound has a good poisoning effect on diaphorina citri and citrus red mites, and can be usedfor preparing insecticides for preventing and controlling corresponding pests.

Description

technical field [0001] The invention relates to extracting and separating active ingredients from plants, in particular to extracting and separating bitternin compounds from bitter wood and its preparation method and application. Background technique [0002] Bitterlignin compounds only exist in Bitterwoodaceae plants. Because of their structural diversity, scientific researchers have never stopped studying this kind of compounds in recent decades. These compounds are considered to be derived from tetracyclic triterpenoids in biogenesis, so picolidinoids are still classified as triterpenoids. Up to now, more than 200 pectinoids have been isolated and identified from the plants of the family Fraulaceae, and some pectinoids have shown significant anti-tumor, anti-malarial and anti-inflammatory biological activities. [0003] Citrus psyllid [Diaphorina citri (Kuwayama)], also known as Oriental psyllid, Asian psyllid, belongs to the family Psyllidae of Homoptera, distributed in...

AI Technical Summary

Problems solved by technology

During the spring citrus tipping period and winter fruit picking period, due to the serious damage of this insect, the leaves often fall off, further causing flower and fruit drop, tree vigor decline, seriously affecting the yield and quality of citrus

[0006] At present, there are no relevant reports on picolidin compounds as insecticides, especially in the control of citrus psyllids and red spiders.
