Biological Activity
Description: 14,15beta-Dihydroxyklaineanone is a plant growth inhibitor. It (IC(50) = 5 microM) shows anti-tumor promoting on tumor promoter-induced Epstein-Barr virus activation.
In vitro:
J Ethnopharmacol. 2002 Sep;82(1):55-8.
In vitro anti-tumor promoting and anti-parasitic activities of the quassinoids from Eurycoma longifolia, a medicinal plant in Southeast Asia.[Pubmed: 12169407]
Some quassinoids (1-6) isolated previously as plant growth inhibitors from the leaves of Eurycoma longifolia Jack. (Simaroubaceae) were subjected to in vitro tests on anti-tumor promoting, antischistosomal and plasmodicidal activities.
METHODS AND RESULTS:
The most active compound for inhibition of tumor promoter-induced Epstein-Barr virus activation (anti-tumor promotion) was 14,15beta-Dihydroxyklaineanone (5, IC(50) = 5 microM). Longilactone (1) gave significant antischistosomal effect at a concentration of 200 microg/ml. 11-Dehydroklaineanone (3) and 15beta-O-acetyl-14-hydroxyklaineanone (6) showed potent plasmodicidal activity (IC(50) = 2 microg/ml).
CONCLUSIONS:
Thus it was suggested that E. longifolia possesses high medicinal values due to the occurrence of a variety of quassinoids.

Source: The herbs of Eurycoma longifolia
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.
