nedione - Introduction
Overview:
FRANGULIN A(FRANGULIN A) is A hydroxyanthraquinone derivative found in the bark of Rhamnus frangula. It has a range of properties and uses.
Nature:
FRANGULIN A is A yellow crystal with A melting point of about 202-204 ℃. It is practically insoluble in water, but soluble in ethanol and ether. Its molecular formula is C30H16O10 and its molecular weight is 544.45.
Use:
1. Killing insects: FRANGULIN A has insect antibacterial activity and can be used to kill pests.
2. Laxative: it can be used as a laxative in the field of medicine to treat constipation and promote intestinal peristalsis.
3. Dye: It can be used as a dye, and can be used in printing and dyeing industries.
Method:
Meihao rhamnoside enzyme in the bark of Meihao rhamnoside can convert Meihao rhamnoside B into Meihao rhamnoside A. The most common extraction method is to grind the bark of Mae Hao rhamnoside and extract it with ethanol or other suitable solvents, and then go through A crystallization and purification process to obtain pure Mae Hao rhamnoside A.
Safety Information:
The following safety information should be paid attention to when using Meihao rhamnoside A:
1. Although rhamnoside A is A natural product, it is still necessary to follow correct operating procedures and safety measures.
2. In the use of the process need to avoid contact with the skin, eyes and respiratory tract, so as not to cause discomfort.
3. Appropriate personal protective equipment should be used during use, such as laboratory gloves and protective glasses.
4. Please read and follow the relevant safety instructions and operating instructions before use to ensure the safety and effectiveness of use.
Please note that the use of rhamnoside A should be in accordance with laws, regulations and regulations, and follow appropriate laboratory techniques and procedures.
