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.

Structure Identification
Acta Pharmaceutica Sinica, 1997, 32(4):282-285.

Studies on liposoluble constituents from the aerial parts of Siegesbeckia orientalis L.[Reference: WebLink]

Eight compounds were isolated from the aerial parts of Siegesbeckia orientalis L. and their structures were elucidated by spectroscopic methods(IR, EI-MS, 13C-NMR, 1H-NMR, 1H-1H COSY, 1H-1H NOESY and 1H-13C COSY).
METHODS AND RESULTS:
Compounds I and II are new natural products and named siegesesteric acid(I) and siegesetheric acid(II), their structures were confirmed as ent-17-acetoxy-18-isobutyryloxy-16(alpha)-kauran-19-oic acid(I) and ent-17-ethoxy-16(alpha)-(-)-kauran-19-oic acid(II). The others were identified as known compounds: ent-16 beta, 17-dihydroxy-kauran-19-oic acid (III), kirenol(IV), beta-sitosteryl glucoside(V), heneicosanol(VI), methyl arachidate(VII) and beta-sitosterol(VIII).
CONCLUSIONS:
These compounds, except kirenol and beta-sitosterol, were isolated for the first time from the title plant.
