|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.|

|Antineoplastic agents. 522. Hernandia peltata (Malaysia) and Hernandia nymphaeifolia (Republic of Maldives).[Pubmed: 14987061 ]|
|Bioassay (P388 lymphocytic leukemia cell line and human tumor cell lines)-guided separation of the extracts prepared from the tropical and coastal trees Hernandia peltata (Malaysia) and Hernandianymphaeifolia (Republic of Maldives) led to the isolation of a new lignan designated as hernanol (1) and 12 previously known lignans: (-)-deoxypodophyllotoxin (2), deoxypicropodophyllin (3), (+)-Epiaschantin (4), (+)-epieudesmin (5), praderin (6), 5'-methoxyyatein (7), podorhizol (8), deoxypodorhizone (9), bursehernin (10), kusunokinol (11), clusin (12), and (-)-maculatin (13). The oxidative cyclization (with VOF(3)) of lignans 8, 9, and 10 resulted in a new and unusual benzopyran (14), isostegane (15), and a new dibenzocyclooctadiene lactone (16), respectively. The structure and relative stereochemistry of hernanol (1) and lignans 3, 7, 8, 9, 10, 11, and 12 were determined by 1D and 2DNMR and HRMS analyses. The structures and absolute stereochemistry of structures 2, 4, 5, 6, 13, 14, 15, and 16 were unequivocally determined by single-crystal X-ray diffraction analyses. Evaluation against the murine P388 lymphocytic leukemia cell line and human tumor cell lines showed podophyllotoxin derivatives 2 and 3 to be strong cancer cell line growth inhibitors and substances 4, 5, 8, and 15 to have marginal cancer cell line inhibitory activities. Seven of the lignans and one of the synthetic modifications (14) inhibited growth of the pathogenic bacterium Neisseria gonorrhoeae.|

|Anti-platelet aggregation alkaloids and lignans from Hernandia nymphaeifolia.[Pubmed: 10821052]|
|A new aporphine, N-(N-methylcarbamoyl)-O-methyl-bulbocapnine (1), together with seven known compounds, (-)-5'-methoxypodorhizol (2), a mixture of beta-sitosterone (3) and stigmasta-4,22-dien-3-one (4), a mixture of 3 beta-hydroxystigmast-5-en-7-one (5) and 3 beta-hydroxystigmasta-5,22-dien-7-one (6), and a mixture of 6 alpha-hydroxystigmast-4-en-3-one (7) and 6 alpha-hydroxystigmasta-4,22-dien-3-one (8), were isolated in continuing studies on the trunk bark of Formosan Hernandia nymphaeifolia. The structures of these compounds were determined through spectral analyses. In addition, the previously reported six alkaloids, laurotetanine, oxohernagine, thalicarpine, reticuline, (+)-vateamine-2'-beta-N-oxide, (+)-hernandaline and six lignans, (+)-Epiaschantin, (+)-epimagnolin, (+)-epiyangambin, (-)-hernone, (-)-yatein, (-)-deoxypodophyllotoxin were demonstrated to have anti-platelet aggregation activity.|

|New dimeric aporphine alkaloids and cytotoxic constituents of Hernandia nymphaeifolia.[Pubmed: 9000885]|
|Three minor new dimeric aporphine alkaloids, oviisocorydine (1), ovihernangerine (2), and oxohernandaline (3), along with four known alkaloids, (+)-hernandaline, (+)-thallcarpine, (+)-N-methylovigerine, and N-methylcorydaldine, and five known lignans, (+)-epimagnolin, (+)-Epiaschantin, (+)-epiyangambin, (-)-deoxypodophyllotoxin, and (-)-yatein, have been additionally isolated from the trunk bark of Hernandia nymphaeifolia. The structures of these compounds were elucidated by spectroscopic methods. Among forty-four isolates obtained till now, nine compounds, hernandonine (4), hernanymphine (5), demethylsonodione (6), (+)-ovigerine (7), (+)-N-methylovigerine (8), N-formyldehydroovigerine (9), 4-methoxyoxohernandaline (10), (-)-deoxypodophyllotoxin (11), and (-)-yatein (12) showed significant cytotoxic activities (ED50 values < 1 microgram/ml) against P-388, KB16, A549, and HT-29 cell lines.|
