Abstract

The invention discloses a tea saponin compound as well as a preparation method and application thereof. The structural general formula of the tea saponin compound is shown in the specification; the tea saponin compound and a plurality of monomers thereof are proved to have insecticidal performance; new application of camellia vegetable oil tea is developed, the tea saponin compound has a strong insecticidal effect on tea geometrid larvae, the structure of the outer epidermis and even the inner skeleton of the tea geometrid larvae can be destroyed through the contact action, and intestinal cells of the tea geometrid eating tea saponin are also greatly destroyed. Through two different action mechanisms, the tea saponin compound can effectively prevent pests, and as an insecticidal compound from a natural plant source, the tea saponin compound has huge potential of becoming a green pesticide.

Description

technical field [0001] The invention relates to a biochemical technology, in particular to a tea saponin compound, a preparation method and an application. Background technique [0002] The use of natural plant metabolites to control harmful insects is a hot topic in pesticide research. At present, it has been confirmed that there are more than one thousand plants with insecticidal active ingredients, and the active ingredients are mainly terpenes, alkaloids, flavonoids, steroids, and phenols. Among them, there are more than 20 kinds of botanical insecticides that have been industrialized, mainly including azadirachtin, phyllotine, matrine, wolftoxin and osthole. [0003] Among substances involved in plant defense, saponins synthesized by several plants have been reported to be substances having a defense effect. Saponins or sapogenins can form numerous hybrids in plants, characterized by their surface-active properties, and they dissolve in water by forming foamy solution...
