|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.|

|Active saponins from root of Pueraria peduncularis (Grah. ex Benth.) Benth. and their molluscicidal effects on Pomacea canaliculata.[Pubmed: 27608163 ]|
|Pueraria peduncularis (Grah. ex Benth.) Benth., which belongs to the Leguminosae family, exhibits resistance to many crop pests in agricultural production. Pomacea canaliculata is an important invasive snail in rice fields and causes severe yield losses. To evaluate the toxicity of P. peduncularis to P. canaliculata, in this study the molluscicidal activity of root extracts of P. peduncularis was tested against P. canaliculata; the active compounds were isolated, and the structures of these compounds were analysed using nuclear magnetic resonance (NMR) analysis and mass spectral analysis. RESULTS: Our results showed that the molluscicidal activity of the root crude extract differed between P. canaliculata with different shell diameters after treatment for 72 h. The median lethal concentration (LC50 ) was 5.511 mg L-1 against snails of 1.5 ± 0.2 cm diameter and 12.383 mg L-1 against snails of 2.5 ± 0.2 cm diameter. Furthermore, two active ingredients isolated from root methanol extracts were identified as pedunsaponin A and Pedunsaponin C. Both pedunsaponin A and Pedunsaponin C showed strong molluscicidal activities, with LC50 values of 3.893 and 4.252 mg L-1 , respectively, against snails with shell diameters of 1.5 ± 0.2 cm after treatment for 72 h. CONCLUSION: Pueraria peduncularis extracts exhibit high molluscicidal activity and have great potential value for exploring a molluscicide to control Pomacea canaliculata.|

|New oleanene-type triterpene saponins from Pueraria peduncularis.[Pubmed: 12450252]|
|Two new oleanane-type triterpene saponins named pedunsaponin B (2) and Pedunsaponin C (3) were isolated from the roots of Pueraria peduncularis. Their structures were determined to be 3-O-(6-O-methyl)-beta-glucuronopyranosyl-3beta,15alpha-dihydroxyolean-12-en-16-one (2), and 3-O-beta-glucopyranosyl-(1 --> 3)-beta-glucuronopyranosyl-3beta,15alpha-dihydroxyoleana-12-en-16-one (3), on the basis of spectroscopic evidence.|
