Suppression of mouse lymphocyte proliferation in vitro by naturally-occurring biflavonoids.[Pubmed: 7623623]

In a continuing effort to investigate biological activities of flavonoids, nine biflavonoids, isolated from three plant sources were evaluated for their suppressive effects on mouse lymphocyte proliferation.
METHODS AND RESULTS:
The biflavonoids tested were amentoflavone, bilobetin, ginkgetin, isoginkgetin, sciadopitysin, ochnaflavone, 4'-O-Methylochnaflavone, cryptomerin B and isocryptomerin. At 10 uM, several biflavonoids such as ginkgetin, isoginkgetin, ochnaflavone, cryptomerin B and isocryptomerin showed the suppressive activity against lymphocyte proliferation induced by Con A or LPS. Apigenin (flavone) and quercetin (flavonol) were suppressive against Con A-induced lymphocyte proliferation, but not against LPS-induced lymphocyte proliferation at the same concentration range. Biflavonoids were found to be irreversible inhibitors of lymphocyte proliferation.
CONCLUSIONS:
This is the first report describing the suppressive effects of naturally-occurring biflavonoids against lymphocyte proliferation.

4'-O-Methylochnaflavone Description

Source:	The leaves of Ginkgo biloba L.
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.
