|Benzene, coumarin and quinolinone derivatives from roots of Citrus hystrix.[Pubmed: 23352239 ]|
METHODS AND RESULTS:
Two coumarins, hystrixarin (1) and (+)-Hopeyhopin (2); a benzenoid derivative, hystroxene-I (3) and a quinolinone alkaloid, hystrolinone (4), along with 33 known compounds were isolated from the crude acetone extract of the roots of Citrus hystrix.
Their structures were determined by analysis of 1D and 2D NMR spectroscopic data. The antioxidant, anti-HIV and antibacterial activities of the isolated compounds were also evaluated.
||The herbs of Micromelum falcatum.
||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
||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. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: email@example.com
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|Study on the chemical constituents from ethyl acetate extract of Micromelum falcatum.[Pubmed: 24218965]|
|To study the chemical constituents from ethyl acetate extract of Micromelum falcatum.
METHODS AND RESULTS:
The constituents were separated and purified by silica gel, Sephadex LH-20 and HPLC. Their structures were elucidated by spectral analysis (NMR, MS).
Ten compounds were isolated and identified as micropubescin (1), phebalosin (2), scopoletin (3), citrubuntin (4), thamnosmonin (5), Hopeyhopin (6), arnottinin (7), casegravol (8), 2-methoxy-5-hydroxy cinnamate (9), threo-syringoylglycerol (10).
Compounds 1 - 10 are obtained from this plant for the first time.
