|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.|

|Antiplasmodial Isoflavanes and Pterocarpans from Apoplanesia paniculata.[Pubmed: 26018916]|
|Bioassay-guided fractionation of an EtOH extract of the roots of the plant Apoplanesia paniculata (Fabaceae) led to the isolation of the three known compounds amorphaquinone (1), Pendulone (2), and melilotocarpan C (3), and the two new pterocarpans 4 and 5. Compounds 1 and 2 exhibited good antiplasmodial activity with IC50 values of 5.7 ± 1.5 and 7.0 ± 0.8 μM, respectively. Compound 3 exhibited weak antiplasmodial activity (41.8 ± 5.2 μM), while compounds 4 and 5 were inactive. Compound 6 was synthesized to confirm the structure of 5, and it showed enhanced antiplasmodial activity (15.8 ± 1.4 μM) compared to its analogues 3-5.|

|Antiparasitic and antimicrobial isoflavanquinones from Abrus schimperi.[Pubmed: 22224279]|
|The EtOH extract of Abrus schimperi (Fabaceae), collected in Kenya, demonstrated significant activity against Leishmania donovani promastigotes with IC50 value of 3.6 microg/mL. Bioassay-guided fractionation of CHCl3 fraction using Centrifugal Preparative TLC afforded two antiparasitic isoflavanquinones, namely amorphaquinone (1) and Pendulone (2). They displayed IC50 values of 0.63 microg/mL and 0.43 microg/mL, respectively, against L. donovani promastigotes. Both the compounds were also evaluated against L. donovani axenic amastigotes and amastigotes in THPI macrophage cultures. In addition, compounds 1 and 2 showed antiplasmodial activity against Plasmodium falciparum D6 and W2 strains, while 2 displayed antibacterial activity against Staphylococcus aureus and methicillin-resistant S. aureus (each IC50 1.44 microg/mL). The 1H and 13C data of 1, not fully assigned previously, were unambiguously assigned using 1D and 2D NMR HMBC and HMQC experiments. In addition, the absolute stereochemistry of the isolated compounds 1 and 2 was revised as C-(3S) based on Circular Dichroism experiments. This appears to be the first report of amorphaquinone (1) and Pendulone (2) from the genus Abrus.|

|In vitro leishmanicidal constituents of Millettia pendula.[Pubmed: 16755071]|
|The in vitro leishmanicidal constituents of Millettia pendula were examined. Two new compounds, 1 (millettilone A) and 2 (millettilone B), were isolated from the methanol extract of M. pendula, together with six known compounds: 3R-claussequinone (3), Pendulone (4), secundiflorol I (5), 3,8-dihydroxy-9-methoxypterocarpan (6), 3,10-dihydroxy-7,9-dimethoxypterocarpan (7), and formononetin (8). Among these, Pendulone showed the most potent leishmanicidal activity. Compound 2 was found to be a purple pigment in this heartwood. Their chemical structures were elucidated using spectral methods.|

|Anti-tumor promoting activities of isoflavonoids from Wistaria brachybotrys.[Pubmed: 9300132]|
|Eight minor isoflavonoids (3-10) isolated from the knot of Wistaria brachybotrys were tested for their inhibitory effects on Epstein-Barr virus (EBV) activation induced by the tumor promoter, 12-O-tetradecanoyl-phorbol-13-acetate (TPA), in Raji cells as a primary screening test for anti-tumor-promoters (cancer chemopreventive agents), and all the tested compounds showed inhibitory activity. Of these compounds, Pendulone (3) was further examined on the cell cycle of Raji cells, and indicated strong inhibition on the effect of the cell cycle induced by TPA. In addition, the compound showed potent anti-tumor-promoting activity for an in vivo two-stage carcinogenesis test of mouse skin using 7,12-dimethylbenz[a]-anthracene and TPA. Consequently, it suggests that 3 could be a valuable chemopreventive agent in chemical carcinogenesis.|
