ZULKA SAVIRA. Standardization of Purple Passion Fruit Peel
Extract (Passiflora edulis var. edulis) (Supervised by Abd. Malik and
Aktsar Roskiana Ahmad)
The peel of purple passion fruit (Passiflora edulis var, edulis)
represents a valuable agricultural product with rich in bioactive
compounds, such as flavonoids and polyphenols. The bioactive
compounds exhibit significant antioxidant, antidiabetic, and
antihypertensive properties. This study aimed to standardize the extract by
determining both specific parameters (extract identity) and non-specific
parameters (extract safety). The extract was obtained through maceration
using 96% ethanol, followed by standardization process. Specific
parameter revealed a viscous, dark brown-to-black extract with distinctive
organoleptic properties (characteristic aroma and bitter taste), containing
16.31% water-soluble and 20.04% ethanol-soluble compounds. The
phytochemical analysis confirmed the presence of alkaloids, flavonoids,
tannins, saponins, and triterpenoids. Meanwhile, the non-specific
parameters were as follows: drying loss of 1.5035%, specific gravity of
0.8099 g/mL, moisture content of 6.9271%, total ash content of 4.5542%,
acid-insoluble ash of 0.5475%, total plate count (TPC) of 2.6 x 105 CFU/g,
total yeast and mold count (TYMC) of 1.0 x 102 CFU/g, cadmium (Cd)
content <0.00003 μg/g, and lead (Pb) content of 0.9768 μg/g.
