Abstract

The invention provides an extraction method of total flavonoids in leaves of turpinia arguta seem. The extraction method is characterized by comprising the following steps: a, taking the leaves of the turpinia arguta seem and crushing the leaves for later use; b, carrying out ultrasonic extraction on medicinal powder with ethanol, and filtering an extracting solution so as to obtain the total flavonoids, wherein the ratio of liquid to materials is 20:1 to 30:1, the ethanol concentration is 40 to 60% v / v, the extraction temperature is 50-70 DEG C, and the extraction time is 40 to 60 minutes. The extraction process disclosed by the invention is easy and simple to operate, low in energy consumption and cost, good in reproducibility, and accurate and reliable in results, thereby providing a theoretical basis for further development of leaf resources of the turpinia arguta seem, and having very important significance to the development and application of the turpinia arguta seem.

Description

technical field [0001] The invention relates to a method for extracting total flavonoids from the round leaves of Shanxiang. Background technique [0002] Turpinia arguta Seem., also known as seven-inch nails, two-finger swords, and thousand hammers, is the dry leaf of Turpinia arguta Seem., a plant of the oil family in Shenggu. It is produced in southern Jiangxi and is recorded in the 2015 edition of "Chinese Pharmacopoeia". Traditional medicinal materials. This product is cold in nature and bitter in taste. It has the effects of clearing away heat and detoxification, relieving sore throat, reducing swelling, promoting blood circulation and relieving pain. Modern studies have shown that total flavonoids are the main substances for their curative effect, and have pharmacological effects such as anti-inflammatory, antibacterial, immune-enhancing, and analgesic. [0003] At present, the extraction methods of total flavonoids from the round leaves of Shanxiang include: ethano...
