| Hazard Information | Back Directory | [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. | [Uses]
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. | [storage]
Store at -20°C |
