Abstract

Carica papaya is an important fruit crop in the tropics and is cultivated for consumption in fresh or processed form and for use in the pharmaceutical, leather, and textile industries. Unlike the papaya fruits that are useful for the food industry, the shoots, leaves, and seeds were discarded as it was considered a waste product. This study was conducted to determine the Carica papaya plant part that will yield the highest phenolic compound by the Folin-Ciocalteu method and to find out which Carica papaya plant part that exhibits the highest antioxidant activity through DPPH free radical scavenging assay. The investigation of antioxidant activity and the total phenolic content of the unused papaya tree parts is significant as the unused parts of the Carica papaya tree like shoots, leaves, and seeds can become potential raw materials for the manufacturing of medicine and drugs. The extraction procedure involved five different solvents and ratios which are methanol, ethanol, and a mixture of methanol and ethanol at 1:1, 1:2, and 2:1 ratio respectively. The shoots of Carica papaya that are extracted with methanol yield the highest phenolic compound with 11.70±0.62 mg GAE/g. The leaves of Carica papaya that are extracted with methanol exhibit the highest antioxidant activity through DPPH free radical scavenging assay with 86.78±0.49%. The present study shows that methanol should be used as the extraction solvent as it is the most efficient solvent in extracting phenolics compound from the Carica papaya plant's part. Extraction using methanol as the solvent could be used for further studies as it can yield maximum phytochemical compounds from the Carica papaya plant as well as other plant samples.
