BALANOCARPOL AND AMPELOPSIN H, TWO OLIGORESVERATROLS FROM STEM BARK OF Hopea odorata (DIPTEROCARPACEAE)[Reference: WebLink]
Two oligoresveratrol, namely balanocarpol (2) and ampelopsin H (3) had been isolated from the steam bark of Hopea odorata (Dipterocarpaceae).
METHODS AND RESULTS:
The structures of these compounds were elucidated based on physical and spectroscopic data (MS, 1 H and 13 C NMR 1D and 2D). The activity of these compounds was evaluated against the 2-deoxyribose degradation induced by the hydroxyl radical generated via a Fenton-type reaction. The result showed that activity each compounds as radical hydroxyl scavenger of balanocarpol, and ampelopsin H with an IC 50 1802.3 and 4840.0 ug/mL. respectively. Each compound showed low activity. Vitamin C (IC 50 83.9 ug/mL) and butylated hydroxyl toluene (1328.0 ug/mL) were used as positif controls.
CONCLUSIONS:
These results suggest that oligoresveratrols from stem bark of H. odorata may be useful as potential sources of natural antioxidants.

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.

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: service@chemfaces.com

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.
