Abstract:

Physalis angulata is widely distributed in the agricultural farms and fruit orchards in the Philippines and commercially grown in other countries like Brazil. Commonly known as wild gooseberries, it is popularly used in traditional medicine as anticoagulant, anti-leucemic, anti-spasmodic, anti-inflammatory and as food. The plant was studied to determine if Physalis angulata can be an herbal oral ProVac for infectious diseases caused by food-borne pathogens. The phytochemical profile of the plant extract was determined using the method of Samy et. al (2008). Antimicrobial assay using the Tube Dilution and Filter Paper Disc Assay methods were done after Gel Permeation Chromatography (GPS) and Solid Phase Extraction (SPE) clean-up and concentration procedures. Fractionated extracts from Physalis angulata showed that the alkaloids, terpenoids, cardiac glycosides and sterols present inhibited the growth of Listeria monocytogenes, Salmonella typhimurium and Escherichia coli. Results of Ames test showed that the combined fractionated extracts exhibited no mutagenic effect against Salmonella typhimurium TA 98. Testing of partially purified herbal extract of Physalis angulata confirmed its antimicrobial activity against all food pathogens tested. In vitro and in vivo studies have to be undertaken to elaborate its medicinal properties prior to development of Physalis angulata for drug and vaccine.
