||The whole plants of Polygala hongkongensis Hemsl.
||DMSO, Pyridine, Methanol, Ethanol, 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.

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.

|Megastigmane Glycosides from Polygala hongkongensis Hemsl.[Reference: WebLink]|
METHODS AND RESULTS:
Two new megastigmane glycosides, 7Z-roseoside, and 7-Z-Trifostigmanoside I, as well as, four known compounds, trifostigmanoside II, epimedin C, 3′,7-dihydroxy-4′-methoxyisoflavone-7-D-glucopyranoside, and formenonetin, were isolated from Polygala hongkongensis Hemsl.
The structures of the isolated compounds were established on the basis of UV, IR, NMR, and MS spectral data. Megastigmane glycosides (1—3) were isolated from the family Polygalaceae for the first time.
