Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 87-72-9, Name is L-Arabinopyranose, SMILES is OC1[C@H](O)[C@@H](O)[C@@H](O)CO1, belongs to dioxoles compound. In a document, author is Schfer, Sibylle, introduce the new discover, Recommanded Product: L-Arabinopyranose.
Aristolic Acid Derivatives from the Bark of Antidesma ghaesembilla
Antidesma ghaesembilla is an important medicinal and food plant in many Asian countries. Ten substances could be isolated from the dichloromethane and methanol extract: sitostenone (3), daucosterol (4), chavibetol (5), asperphenamate (6), protocatechuic acid (7), vanillic acid-4-O-beta-D-glucoside (8), 1-O-beta-D-glucopyranosyl- 3-O-methyl-phloroglucinol (9), and aristolic acid II-8-O-beta-D-glucoside (10), and two new aristolic acid derivatives, 10-amino-5,7-dimethoxy-aristolic acid II (= 6-amino-9,11-dimethoxyphenanthro[3,4-d]-1,3-dioxole-5carboxylic acid; 1) and 5,7-dimethoxy-aristolochic acid II (= 9,11-dimethoxy-6-nitrophenantro[3,4-d]-1,3-dioxole-5carboxylic acid; 2). Exposure to humans of some of these compounds is associated with a severe disease today known as aristolochic acid nephropathy. Therefore, the traditional usage of this plant has to be reconsidered carefully.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 87-72-9 is helpful to your research. Recommanded Product: L-Arabinopyranose.
