[0037] Take 150Kg of washed fresh lycoris bulbs and slice them, soak them in a functional extraction tank, add 2.1L of liquid cellulase (enzyme activity is not less than 2000u / ml), then add 600Kg of water, at a temperature of 55 ° C, pH =5, enzymolysis for 6 hours, filter after enzymolysis is completed, discard filter residue (filter residue can be used as fertilizer), get filtrate 700Kg, adjust enzymolysis solution pH9~10 with 40% sodium hydroxide aqueous solution by filtrate, make enzymolysis solution turbid , use GQ75 high-speed tubular separator to centrifugally separate and remove slag (used as fertilizer) to obtain 740Kg of centrifugate, take the centrifugate, and extract on average 6 times with 2960L ethyl acetate. , Discard the water phase, and the discarded water phase can be discharged to the sedimentation tank, adjusted to PH=7 and left for 24 hours before discharge. Concentrate the organic phase to about 15Kg with a scraper thin film concentrator, recover ethyl ace...

Abstract

The invention discloses a technology method for distilling short-tube lycoris alkali from short-tube lycoris plants. It supplies the technology process and condition to distill short-tube lycoris alkali from the stem tuber of short-tube lycoris through cellulose enzyme enzymolysis. The purity of the product could reach 99%. And the method is easy to operate, and high efficient. The yield could reach 4.69 per ten thousand.

Description

technical field [0001] The invention relates to a method for extracting lycorine from plants of the genus Lycoris. Background technique [0002] Lycoris, also known as dragon claw flower, is a perennial herb bulb flower, one of the precious flowers in China, with many varieties, including safflower, small safflower, yellow flower, lavender purple, lily type, white long tube type, etc. Its leaves Like orchids, the flower shape is like a golden lamp, which has good ornamental value. In plant taxonomy, it belongs to the family Amaryllidaceae (Anaryllidaeeae) and the genus Lycoris (Lycoris.herb). The Latin meaning of its genus name is the name of the goddess of the sea in Greek mythology. [0003] There are about 20 species of Amaryllis distributed in the world, and there are 15 species in my country, which occupy an absolute advantage. They are distributed in 12 provinces, municipalities, and autonomous regions. They are distributed wildly from the south of the Qinling Mountai...
