Salkowski’s test: One milliliter of banana florets’ extract was dissolved in 2 mL of chloroform and a few drops of sulphuric acid was added carefully. A reddish brown color ring was formed in the interface. This indicates the presence of steroids.

Salkowski test: When shaken with concentrated sulfuric acid, the lower layer of a chloroform solution of the test drug will turn yellow on standing.Lieberman–Burchard test: A chloroform solution of the test drug with a few drops of acetic acid and one mL of concentrated sulfuric acid produces a deep red at the junction of the 2 layers.Tschugajen test: A chloroform solution of the test drug with an excess of acetyl chloride and a pinch of zinc chloride, when warmed in a water bath, produces an Eosin red color.

Preliminary phytochemical properties of the aqueous extract of Ocimum gratissimum leaves were tested using the following chemicals and reagents: flavonoids (NaCl and HCl), alkaloids (Mayer and Dragendorff’s reagents), saponins (frothing test), tannins (FeCl3), cardiac glycosides (Salkowski test), terpenoids (Borntrager’s reaction), phenols [FeCl3 and K3Fe(CN6)] [16].

The hexane, ethyl acetate and aqueous fractions were analysed for the presence of sterols using the Liebermann–Burchard test; triterpenes using Salkowski’s test; flavonoids using magnesium turning test; alkaloids using Mayer’s test; saponins using Froth test; glycosides using Fehling’s test; and tannins using ferric chloride test (Evans 2002). The fractions were tested at the STD-ITDI DOST.

The phytochemical screening was carried out by using the standard methods for reducing sugars (Fehling’s test), terpenoids (Salkowski’s test), flavonoids (Shinoda’s test), phenolic compounds (ferric chloride test), saponins (foam test), steroids (Libermann Burchard’s test), cardiac glycosides (Keller-Killiani test), and alkaloids (Dragendorff’s test) [21–23].
