What is HOMOPLANTAGININ?

Chemical properties

Homoplantaginin belong to flavonoids, easily soluble in methanol and ethanol, slightly soluble in acetone, and insoluble in water. Its hemihydrate is a yellow crystal.

The Uses of HOMOPLANTAGININ

Homoplantaginin has bacteriostatic effect. It has moderate inhibitory effect on the common pathogenic bacteria of chronic bronchitis such as Staphylococcus albus and pneumococcus in vitro. It has a certain antagonistic effect on the infection of Staphylococcus aureus in animals, and can reduce the mortality rate 20 %. It has certain antitussive and expectorant effects, and its expectorant ability is greater than that of ammonium chloride. It can be used to treat chronic bronchitis with less toxicity.

Definition

ChEBI: Homoplantaginin is a glycoside and a member of flavonoids.

Synthesis

Extraction process of Homoplantaginin in lychee grass: lychee grass decoction pieces--crushing--solvent extraction--filtration and decompression concentration--extraction--dehydration--suction filtration silica gel column separation--purification (recrystallization)--suction filtration-- dry.
