Alkaloid test: Conducted by the method of Mayer, Wagner and Dragendorff. A sample of 3 mL was added with 5 mL of 2 M HCl, stirred and cooled at room temperature. After that, 0.5 g of NaCl was added to the already cool sample then stirred and filtered. The filtrate obtained was added with drops of 2 M HCl, then separated into 4 parts (A, B, C, D). Filtrate A was used as blank, filtrate B was added to Mayer's reagent, filtrate C was to be added to Wagner reagent, while filtrate D was used for the confirmation test. Precipitate would be formed on the addition of Mayer and Wagner reagents, when identification indicates the presence of alkaloid. Confirmation test was carried out by adding 25% ammonia to filtrate D until PH changed to 8-9. Then chloroform was added, and evaporated in water bath. Then 2M HCl was added, stirred and filtered. The filtrate was divided into 3 parts. Filtrate A was used as blank, filtrate B was tested with Mayer's reagent, while filtrate C was tested with Dragendorff's reagent. The formation of a precipitate indicated the presence of alkaloid.Tannin test: 2 grams of sample was put into a mL boiling flask, then added 350 mL of distilled water and refluxed for 3 hours. The sample was cooled and transferred into 500 ml volumetric flask, then filtered and 2 ml of the filtrate was put into a 100 ml volumetric flask. 2 ml of Folin Denis reagent and 5 ml of saturated Na 2 CO 3 were added and allowed to stand for 40 minutes then the absorbance was measured at wavelength of 725 nm.
