Phytochemical Screening: Nanochlorum spp

 

Abstract:

This study attempted to screen selected phytochemicals in the ethanolic, methanolic and acetone extracts of Nanochlorum spp. The extracts were subjected to the following tests: Test tube method for Alkaloid Analysis (Confrmatory test, test for quaternary bases and/or amine oxide), Test Tube Reaction Methods for Steroids (Keller-Kiliani test: test for 2-deoxysugars), the Bornträger’s Test for Anthraquinones, Test tube Screening Methods for Flavonoids (Test for leucoanthocyanins: Bate-Smith and Metcalf 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.
