Motor Mechanism of Berberis Stamens

Biphenyls from Berberis koreana.

Three new biphenyls, berbekorin A (1), 2'-hydroxy-3,4,5-trimethoxybiphenyl (2), and 4,5-dihydroxy-3-methoxybiphenyl (3), together with 11 known biphenyls (4-14), were isolated from the n-hexane-soluble fraction of the MeOH extract of the trunk of Berberis koreana. The structures of 1-3 were determined by spectroscopic methods, including 1D and 2D NMR analysis. Compound 1 exhibited cytotoxic act...

Possible mechanism of cardiac depressant activity of Berberis orthobotrys roots in isolated rabbit heart.

Berberis orhob, otrvs Bien. ex Aitch. (B.o.) has been reported to have antihypertensive effect in different experimental models. The aim of present study was to evaluate the possible antihypertensive mechanism. Aqueous methanolic extract of B.o. roots and its various fractions namely (ethyl acetate, n-butanol or aqueous) in different concentrations (10 ng/mL, 100 ng/mL, I pg/mL, 10 pg/mL, 100 p...

Ectopic expression of SUPERMAN suppresses development of petals and stamens.

The floral regulatory gene SUPERMAN (SUP) encodes a C2H2 type zinc finger protein that is required for maintaining boundaries between floral organs in Arabidopsis. It has been proposed that the main function of SUP is to balance cell proliferation in the third and fourth whorl of developing flowers, thereby maintaining the boundaries between the two whorls. To gain further insight into the func...
