Embodiment Construction

[0006] The extraction process of the present invention is as follows: Chinese toon flavonoids powder, saponin powder → packaging

[0007] Below is a specific embodiment of the present invention

[0008] After the old leaves of Chinese toon are dried naturally, they are roughly crushed with a pulverizer, put into an extraction device, add 60% ethanol 30 times the weight of Chinese toon powder, keep warm at 60°C for 60 minutes, extract twice, and the extracts are filtered and combined , and then vacuum rotary evaporation at 55°C to obtain a viscous tan extract, which was vacuum-dried at 50°C for 10 hours, and the solid product was crushed and packaged to obtain Toona flavonoids and saponin powder.

Abstract

The present invention relates to separating and extracting technology, and is especially the process of extracting flavone and saponin from old Chinese toon leaf in high yield. The old Chinese toon leaf after pre-treatment is twice extracted with 60% concentration alcohol solution in 30 times the weight of Chinese toon leaf at 60 deg.c for 60 min each, and through the subsequent filtering, concentrating and drying, flavone and saponin may be produced simultaneously in the extraction rate of 90%. The technological process has no pollutant exhaust, and the obtained product is used as medicine material.

Description

Technical field [0001] The invention relates to a method for extracting natural active substances, and more specifically proposes a process for simultaneously extracting total flavonoids and total saponins from old leaves of Toona sinensis. Background technique [0002] A large number of clinical experiments at home and abroad have proved that flavonoids and saponins have a wide range of pharmacological activities, such as antibacterial and anti-inflammatory, anti-oxidation, lowering blood pressure, regulating blood sugar, scavenging oxygen free radicals, and softening blood vessels. Among them, ginkgo flavonoids have entered clinical use. However, its resources are limited, and it is difficult to remove ginkolic acid which has side effects. Therefore, it is necessary to find new flavonoid resources to replace ginkgo flavonoids to meet clinical needs. Chinese toon contains flavonoids, but currently Chinese toon is mainly used as a seasonal vegetable for human consumption, w...
