Problems solved by technology

The method uses cellulase to change the permeability of the potato leaf cell wall, and then uses lipase to hydrolyze the bound solanesol, which overcomes the traditional process of direct extraction followed by purification or reagent extraction followed by alkali saponification to cause solanesol degradation or isolysis Structured, resulting in a lower yield

Abstract

The invention discloses a method of double enzymatic coupling reaction assisted extraction of solanesol. In the method, a cellulase is used for changing the permeability of cell walls of potato leaves and then lipase is used for hydrolyzing combined solanesol. The method overcomes the shortcoming of the lower yield caused by the degradation or isomerization of solanesol as the solanesol is extracted by the traditional process, then is purified or extracted with a reagent and finally is saponified with alkali.

Description

technical field [0001] The invention relates to a method for extracting solanesol by using dried potato leaves as raw materials and adopting a double-enzyme coupling method. Background technique [0002] Solanesol (Solanesol) is a long-chain semiterpene alcohol compound, which is an unsaturated nona-prenyl primary alcohol and belongs to tetrasesquiterpene alcohol. It has a unique chain-like isolated polyene structure and can be used as It is an important raw material for the synthesis of many drugs and plays a very important role in biochemistry. It mainly exists in Solanaceae plants, such as tobacco leaves, eggplant leaves, potato leaves, mulberry leaves, etc. Solanesol has the functions of antibacterial, anti-inflammatory, anti-ulcer and treatment of cardiovascular diseases. It is widely used in medicine and can be used as a synthetic raw material intermediate for ubiquinone drugs, antiallergic drugs, antiulcer drugs, hypolipidemic drugs and anticancer drugs.
