Abstract

The invention discloses a scindapsus aureus flower extraction process which comprises the following steps: preparing scindapsus aureus flowers into powder, extracting for 1-2.5 hours by adopting an ethanol solution with the concentration of 70-85% according to the solid-liquid ratio of 1: (10-15) g / ml, filtering an ethanol extract to obtain a first filtrate for later use, extracting filter residues with hot water, filtering a water extract to obtain a second filtrate, and filtering the second filtrate to obtain the scindapsus aureus flower extract. And uniformly mixing the second filtrate with 90-95% ethanol according to a volume ratio of 1: (10-15), standing, filtering, collecting an alcohol precipitation solution, combining the alcohol precipitation solution with the first filtrate, and distilling to obtain the extract. The method can effectively improve the extraction effect of the active ingredients of the scindapsus aureus flowers, so that the effect of extracting coumarin and other ingredients through hot water and then alcohol is good, and a better blood pressure reducing effect is obtained.

Description

technical field [0001] The invention relates to the technical field of pothos flower extraction. More specifically, the present invention relates to a kind of pothos flower extraction process and its application. Background technique [0002] Green dill is a kind of Tibetan medicine. It is produced in the cold region of Tibet. It is slightly cold in nature. Its growth period is only more than 40 days. It is a unique and precious herb in Tibet. Only Tibet can grow it. The end of October is the picking season for green dill. Green dill flower has many functions. In addition to being used as a medicinal material in prescriptions to increase the efficacy of medicines and treat diseases, it is also often used as a companion in tea soup. [0003] Usually, the medicinal components of the pothos flower are obtained by decocting, soaking, etc., and the utilization rate is low, which affects the development of the medicinal active ingredients of the pothos flower. [0004] Although ...
