The application belongs to the field of enzyme genetic engineering, and particularly relates to application of a sesquiterpene synthase and a mutant thereof in synthesis of enantiomeric-drimenol compounds, wherein the sesquiterpene synthase is a sesquiterpene synthase from Chenopodium quinoa Willd., and includes CqDMDS1 or CqDMDS2; the mutant of the sesquiterpene synthase is a mutant CqDMDS1 in which an amino acid at position 443 of CqDMDS1 is mutated F443A / G The application realizes heterologous expression of the sesquiterpene synthase and the mutant thereof from Chenopodium quinoa Willd. in an Escherichia coli and a N. benthamiana expression system, catalyzes synthesis of (-)‑8,11-driman-diol or (+)‑drimenol. It is found through activity test that the sesquiterpene synthase from Chenopodium quinoa Willd. has a significant inhibitory effect on plant pathogenic fungi Phytophthora nicotianae, Phytophthora sojae and Fusarium graminearum. The sesquiterpene synthase and the mutant thereof and the biological preparation of the catalytic product have important significance for development of biological pesticides.

The application discloses a weight-reducing traditional Chinese medicine preparation and a preparation method thereof. The weight-reducing traditional Chinese medicine preparation is prepared from radix puerariae, pericarpium citri reticulatae, coix seed, poria cocos, mulberry, dioscorea, lotus seed, prepared astragalus root and chenopodium quinoa. The weight-reducing traditional Chinese medicine preparation has the effects of invigorating the spleen and expelling dampness, nourishing yin and blood and calming the heart and soothing the nerves, is used for controlling weight and reducing fat, and is suitable for people with obesity.
