[0002] The main components of rhubarb, a traditional Chinese medicine, in hemorrhoid tablets are emodin and chrysophanol, and their content is an important indicator for drug measurement; since the above-mentioned main components of rhubarb are greatly affected by the decoction time and heating temperature, too long heating time will cause Its content is reduced, and the heating time is too short, then the extraction is incomplete. The extraction method of rhubarb in the Chinese Pharmacopoeia is: add water and decoct twice, the first time 10 times the amount of water, the second time 9 times the amount of water, because the amount of water added is relatively large. Many, longer heating time, insufficient

Abstract
The invention discloses an extraction method of active ingredients of a traditional Chinese medicinal material rhubarb, belonging to the technical field of traditional Chinese medicine extraction and aiming to provide a new rhubarb extraction method with high efficiency and good extraction effects. The extraction method is characterized in that extraction is carried out by adopting twice water extraction modes, wherein the extraction conditions are as follows: 7-8 times amount of water is added during first extraction, 5-6 times amount of water is added during second extraction, the temperature is maintained at 96+ / -2 DEG C after boiling, and the extraction time every time is one hour. The method is mainly used for extracting the active ingredients of the traditional Chinese medicinal material rhubarb.
Description
technical field [0001] The invention relates to a technology for extracting Chinese medicinal materials, more specifically, it relates to a method for extracting effective components of rhubarb, a traditional Chinese medicinal material. Background technique [0002] The main components of rhubarb, a traditional Chinese medicine, in hemorrhoid tablets are emodin and chrysophanol, and their content is an important indicator for drug measurement; since the above-mentioned main components of rhubarb are greatly affected by the decoction time and heating temperature, too long heating time will cause Its content is reduced, and the heating time is too short, then the extraction is incomplete. The extraction method of rhubarb in the Chinese Pharmacopoeia is: add water and decoct twice, the first time 10 times the amount of water, the second time 9 times the amount of water, because the amount of water added is relatively large. Many, the heating time is longer, and there are defici...
