چکیده

A new minor polyoxygenated triterpene named glutinolic acid (1) and two new aeginetic acid quinovosides (2, 3) were isolated from the roots of Rehmannia glutinosa LIBOSCH. (Scrophulariaceae) cultivated in Gunwi-gun, Korea. The structures of these compounds were established as 3α,19α,20β,24,30-pentahydroxyurs-12-en-28-oic acid (1, glutinolic acid), aeginetic acid 5-O-β-D-quinovoside (2) and aeginetoyl ajugol 5″-O-β-D-quinovoside (3) on the basis of chemical and spectroscopic evidence.

A New Ionone Glycoside and Three New Rhemaneolignans from the Roots of Rehmannia glutinosa.

A new ionone glycoside, frehmaglutoside I (1), and three new rhemaneolignans A-C (2-4) were isolated from the 95% EtOH extract of the roots of Rehmannia glutinosa. Their structures were determined by extensive spectroscopic (UV, IR, HR-ESI-MS, 1D and 2D NMR) analyses. In addition, these compounds were evaluated for their protective effects on cardiocytes impaired by doxorubicin in H9c2 cells. A...

ANTIOXIDANT PROPERTIES OF METHANOLIC EXTRACTS FROM THE SHOOTS AND ROOTS OF pRi-TRANSFORMED PLANTS OF REHMANNIA GLUTINOSA LIBOSCH.

The antioxidant activity of methanolic extracts derived from shoots (HR-shoots) and roots (HR-roots) of pRi-transformed Rehmannia glutinosa plants were determined. The activity was indicated by the ability of the plant extracts to inhibit superoxide anion (O2(-·)) generation and thiobarbituric acid reactive substances (TBARS) production in resting blood platelets and platelets activated by thro...
