General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Chemical constituents of the roots of wild Stemona sessilifolia.[Reference: WebLink]

To study the chemical constituents of the roots of wild Stemona sessilifolia (Miq.) Miq. collected in Baohua Mountain, Jurong City, Jiangsu Province.
METHODS AND RESULTS:
The roots of wild S. sessilifolia were extracted with 75 % EtOH and partitioned by CHCl3 and n-BuOH. The compounds were separated and purified by column chromatography with silica gel and macroporous resin, and their structures were identified by spectroscopic analyses. Ten compounds were isolated from the root of S. sessilifolia in this study, i. e., one new dihydrophenanthrene named 7-methoxy-3-methyl-2,5-dihydroxy- 9, 10-dihydrophenanthrene (1), and 9 of known compounds: stilbostemin D (2), protostemonine (3), Protostemotinine (4), stemospironine (5), (-)-syringaresinol-4-O-β-D-glucopyranoside (6), benzoic acid (7), vanillic acid (8), daucosterol (9), and stigmasterol (10).
CONCLUSIONS:
Compound 1 is a new compound, compound 6 is isolated from the genus for the first time, and compounds 7 - 10 are isolated from the species for the first time.
