Anti-Microbial Activities and Phytochemical Screening of The Premna Odorata Blanco (Alagaw) Leaf  Extract

Anti-Microbial Activities and Phytochemical Screening of The Premna Odorata Blanco (Alagaw) Leaf Extract

The researcher focused mainly to determine the antimicrobial properties and phytochemical screening of the Alagaw leaf extract. Specifically, this study was conducted to determine the percent yield, antimicrobial activities and the secondary metabolites of Alagaw leaf extract which was analyzed and it include alkaloid, anthraquinone, saponins and steroid. Findings of the study showed that the Alagaw leaf extract has a percent yield of 11.5 . Anti Microbial Activity was tested by petri disk on a plate Nutrient Agar streaked with the E. coli bacteria, the plates were incubated for 24hrs and 37oC. Results were observed for the presence of zone inhibition clear area around the test disk. Results from this study showed that the antimicrobial activity on E. coli as indicated as negative by the presence of Alagaw leaf extract. Furthermore, the result suggests that the Alagaw leaf extract did not suppress the growth of the E. coli bacteria, hence it indicates that it has no anti microbial effect to the test organism. While the secondary metabolites such as alkaloid, anthraquinone, saponins and steroid is found negative. It is therefore recommended that further study of the chemical properties of alagaw leaf extract, barks and roots should be conducted Bernadette C. Mollejon | Charito V.

Phytochemical Screening of Justina Gendarussa Burm F. (Panhauli) Leaf Extract

Phytochemical Screening of Justina Gendarussa Burm F. (Panhauli) Leaf Extract

This study was conducted to determine the secondary metabolites present in the leaf extract of Justina gendarussa Burm. F. locally known as Panhauli. These metabolites include alkaloids, anthraquinones, leucoanthocyanin, phenolic compound, saponin, steroid, tannin, and terpenoids. Results of the study showed that there was a 30 of extract yielded for every 100 grams of plant leaf. Physical properties of the extract of Panhauli leaves showed that it has a 103. 3oC boiling point, brown color and a pleasant odor, its density was 1.02g mL and a neutral pH. Further physical test showed it is miscible in methanol and water, and immiscible in chloroform and dichloromethane which signifies that the Panhauli leaves extracts has a polar components. Finally phytochemical tests of the Panhauli extract showed the confirmed positive results in alkaloid and saponin only, other secondary metabolites mentioned here in this study were deemed negative.
