CHEMICAL EXAMINATION OF A NEW ALLELOCHEMICAL FROM STEMS OF GLOSSOCARDIA BOSVALLIA DC.
AbstractGlossocardia bosvallia DC.1-3 belongs to family Composite which is commonly known as “Patthar-suva or seri” in Hindi. It is found almost throughout in India and Deccan Peninsula. It is a small annual herb, 10-20 cm tall. The tribal inhabitants of western Maharashtra use a decoction of the plant as febrifuge. It has a bitter taste and fennel like odor. Besides serving as a medicinal plant Pithari plant is also used in culinary purposes. In the present paper, we report the isolation and structural elucidation of a new allelochemical 5,6,7,4′, tetrahydroxy 3-methoxy flavone -7-O-b-D xylopyranosyl (1→4)-O-b-D- glucopyranoside (A) which showed antiviral activity , alongwith two known compounds 6, 4΄-dimethoxy-5, 7-dihydroxy-flavone (B) and Isoorientin (C) from methanolic extract of the stems of this plant.
