A Comparative Study of Phytoconstituents, Antioxidant Activity and Hptlc Finger Printing of Methanolic Extracts of E. Globules and E.Hybrid

Abstract

In the present work we have estimated the phytochemical constituents and HPTLC finger printing of methanolic extract of two species of Eucalyptus, E. globulus and E. hybrid and also studied its antioxidant activity. The primary screening of phytoconstituents shows that these two species have wide difference of phytochemicals. The total polyphenolic content curve and flavonoid curve shows the difference of quantity. The HPTLC fingerprinting of these species confirms that these species have wide difference. Its antioxidant activity were assessed by DPPH Scavenging activity in terms of ascorbic acid IC50 = 36.23in which E. globulus (pure) represents more scavenging activity at IC50 = 48.42 in comparison of IC50 = 59.68.
