Abstract:

This study attempted to screen selected phytochemicals in the ethanolic, methanolic and acetone extracts of Nonochlorum spp. The extracts were subjected to the following tests: Test tube method for Alkaloid Analysis (Confirmatory test, test for quaternary bases and/ or amine oxide), Test Tube Reaction Method for Steroids (Keller- Kiliani test: test for 2- deoxysugars), the Borntrager's Test for Anthraquinones, Test tube Screening Methods for Flavonoids (Test for leucoanthocyanins: Bate- Smith and Metacalf method), and the Test tube Screening Method for Tannins (Ferric chloride test). Results showed that in all Nanochlorum spp. extract, steroids, anthraquinones and tannins were positive (with slight precipitation) but negative with alkaloids and flavonoids.
