, p. 1815 - 1818 (2019/07/18)
A new flavone glycoside was isolated from ethanolic extract of stem parts of Holmskioldia sanguinea Retz. Its structure was characterized as 3,4′-dihydroxy-5,7-dimethoxyflavone-3-O-β-D-galactopyranosyl(1→4)-O-β-D-arabinopyranosyl-4′-O-α-L-rhamnopyranoside (1) by colour reactions, chemical degradation and spectroscopic analysis. Antibacterial activity of compound 1 was evaluated against various Gram positive and Gram negative bacteria showing a significant effects.

, p. 4902 - 4904 (2013/07/28)
A new allelochemical (1), m.p. 282-284 °C, m.f. C31H 36O19, [M]+ 712 (FABMS), has been isolated from methanolic extract of the seeds of Adenanthera pavonina Linn. alongwith two known compounds 2',4',7-trihydroxy isoflavone and isovitexin. The structure of a new compound was characterized as 3,5,7,3',4'-pentahydroxy flavone-3'-O-α-L- rhamnopyranosyl-(1→4)-O-α-L-arabinopyranosyl-(1→3)- O-b-D- xylopyranoside, by various colour reactions, spectral analysis and chemical degradations.

experimental part, p. 1620 - 1627 (2012/04/11)
Fucogalactans from edible Agaricus bisporus (RFP-Ab) and wild Lactarius rufus (RFP-Lr) mushrooms were obtained on aqueous extraction followed by purification. RFP-Ab had Mw 43.8 × 104 g mol -1 and RFP-Lr Mw 1.4
