2H-1-Benzopyran-5-ol Description

Source:	The barks of Rhus chinensis
Solvent:	Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage:	Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C). Wherever possible, you should prepare and use solutions on the same day.

Two new metabolites from Daldinia eschscholtzii, an endophytic fungus derived from Pogostemon cablin.[Reference: WebLink]

METHODS AND RESULTS:
The chemical investigation of the mycelia of endophytic fungus Daldinia eschscholtzii A630, which was isolated from the medicinal plant Pogostemon cablin, resulted in the isolation of two new compounds, named eschscholin A (1), 3-ene-2-methyl-2H-1-Benzopyran-5-ol (2), and one new natural product 3,5-dihydroxy-2-methyl-4H-chromen-4-one (3), along with seven known compounds. Their structures were fully characterized by means of detailed spectroscopic analysis, and in comparison with published data for known compounds.
CONCLUSIONS:
All of the isolated compounds (1-10) were evaluated for their antibacterial activities.
