General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Biological Activity of 2H-1-Benzopyran-7-yloxy

In vitro

Antimicrobial and cytotoxic activity of the stem and root bark extracts of Quassia undulata and isolated constituents.[Reference: WebLink]

Toxicological & Environmental Chemistry Reviews, 2009, 91(5):999-1003.


METHODS AND RESULTS:
The stem and root barks of Quassia undulata were exhaustively extracted with methanol to give the methanolic extracts: MeQuS and MeQuR, respectively. The chloroform extracts were obtained and fractionated on an open column of silica gel by gradient elution with chloroform and chloroform–methanol mixtures. Purification of fractions afforded the isolation of four compounds, namely: 3′-(8-hydroxy,6-methoxy,2-oxo-2H-1-Benzopyran-7-yloxy)-3′,4′-dihydro, 7′-methoxy,2H-1-benzopyran (eniotorin) (1) a new bisbenzopyran coumarin, 7-hydroxy-6-methoxy-2H-1-benzopyran-2-one (scopoletin) (2) (a coumarin); glaucarubinone (3) and 15-desacetylundulatone (4) (quassinoids). The antimicrobial activities of the extracts and isolated compounds were evaluated against five microbes, namely: Staphylococcus aureus; Eschericha coli; Pseudomonas aeruginosa; Klebsiella pneumonia and Candida albicans.
CONCLUSIONS:
The extracts exhibited a broad-spectrum activity against the tested microbes. Cytotoxic activities of the extracts and compounds isolated from them were also examined against brine shrimps, Artemia salina. The extracts and the compounds showed significant dose-dependent activities.
