Problems solved by technology

However, this document does not record which method is used for extraction, nor does it record the extraction temperature
Although the current conventional extraction methods include reflux, ultrasound, and immersion, the reflux method needs to be combined with a specific reflux temperature. Ultrasonic extraction also involves extraction temperature. The immersion process is also divided into cold immersion...

Abstract

The invention provides an ultrasonic extraction method for a radix bupleuri and white paeony root medicine pair. The ultrasonic extraction method for the radix bupleuri and white paeony root medicine pair comprises the following operation steps: (1) preparing radix bupleuri and white paeony root in ratio of (1-3):(1-3), smashing for later use; (2) carrying out ultrasonic extraction on medicine powder with ethanol, and putting extracting solutions together, wherein ethanol concentration is 75-78%v/v, the feed liquor ratio is that 1g medicine powder contains 23-24ml ethanol, an extraction temperature is 74-75 DEG C, extraction time is more than 60 minutes, and extraction frequency is more than twice. The ultrasonic extraction method for the radix bupleuri and white paeony root medicine pair is simple in operation, high in extraction efficiency and obviously better than multiple methods such as refluxing and dipping, and a new choice is provided for effective extraction of the radix bupleuri-white paeony root medicine pair.

Description

technical field [0001] The invention relates to an extraction method of Radix Bupleuri and Radix Paeoniae Alba. Background technique [0002] The compatibility of Bupleurum-White Paeoniae Alba can be found in Xiaoyao San in Taiping Huimin Hejiju Prescription and Sini San and Da Chaihu Decoction in Treatise on Febrile Diseases. The compatibility ratio in both Xiaoyao San and Sini San is 1:1 . Bupleurum soothes the liver and relieves stagnation, Xinsan is good at action, white peony nourishes yin and blood, softens the liver and calms the liver. The combination of the two can make the liver qi flow and the liver blood can be nourished, which embodies the treatment principle of liver disease in traditional Chinese medicine. Commonly used drug pairs for liver depression and blood deficiency. Modern pharmacological studies of ingredients have shown that Xiaoyao San, Sini San, Chai-Guishao (the monarch and minister medicine of Xiaoyao San), Bupleurum-White Paeoniae [1] And sing...
