Abstract

The article presents an analysis of the venom of snake Naja naja karachiensis using inductively coupled plasma optical emission spectrometry (ICP-OES) to study the effect of metals and nonmetal present in the venom taken from Punjab province of Pakistan. Particular focus is given to the enzymes present in the venom of the snake including protease, alkaline phosphatase, and 5'-nucleotidase. Toxic effects of various metal ions in the venom are also discussed.

Abstract

Abstract: An ethyl acetate extract of Artemisia herba-alba was partitioned by HPLC in 10 fractions that were tested in the [3H]-flumazenil radioligand assay, for affinity to the GABAA-benzodiazepine receptor. Two fractions showed activity from which hispidulin and cirsilineol were isolated. The structures were confirmed by 1H NMR. The IC50 values were 8μM for hispidulin and 100μM for cirsilineol.
