|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. 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.

|After receiving:||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.|

|Anthraquinones from the roots of Knoxia valerianoides.[Pubmed: 22308688]|
|To investigate the chemical constituents of the roots of Knoxia valerianoides and their biological activities. METHOD: The anthraquinones were isolated by using a combination of various chromatographic techniques including column chromatography over silica gel, Sephadex LH-20, and reversed-phase HPLC. Structures of the isolates were identified by their physical-chemical properties and spectroscopic analysis including 2D NMR and MS. Antioxidant, anti-HIV, neuroprotective, and cytotoxic activities were screened by using cell-based models. RESULT: Twenty-two constituents were isolated from an ethanolic extract of the roots of K. valerianoides. Their structures were identified as nordamnacanthal (1), ibericin (2), rubiadin (3), damnacanthol (4), 2-ethoxymethylknoxiavaledin (5), 3-hydroxymorindone (6), knoxiadin (7), 2-formyl knoxiavaledin (8), lucidin (9), xanthopurpurin (10), 1, 3-dihydroxy-2-methoxy-9, 10- anthraquinone (11), lucidin(-methyl ether (12), digiferruginol (13), 3-hydroxy-2-methyl-9,10-anthraquinone (14), rubiadin-1-methyl ether (15), 6-methoxylucidin (-ethyl ether (16), 1,3,6-trihydroxy-2-methyl-9,10-anthraquinone (17), 1,3-dihydroxy-2-hydroxy methyl-6-methoxy-9,10-anthraquinone (18), 1,3,6-trihydroxy-2-methoxymethyl-9,10- anthraquinone (19), 3,6-dihydroxy-2- hydroxymethyl-9,10-anthraquinone (20), and 1,6-dihydroxy-2-methyl-9,10-anthra quinone (21). In the in vitro assays, at a concentration of 1 x 10(-5) mol x L(-1), no compounds were active against human cancer cell lines (HCT-8, Bel7402, BGC-823, A549, and A2780), deserum and glutamate induced PC12-syn cell damage, LPS induced NO production in macrophage, Fe2+-cystine induced rat liver microsomal lipid peroxidation, HIV-1 replication, and protein tyrosine phosphatase 1B (PTP1B). CONCLUSION: Compounds 9-21 were obtained from the roots of K. valerianoides for the first time.|
