Passiflora edulis Sims

Family ► Passifloraceae.

Habitat ► Native of Brazil; cultivated in Tamil Nadu, Kerala and Andhra Pradesh, in North India in Punjab and Himachal Pradesh.

English ► Purple Granadilla, Passion Fruit.

Action ► Juice from purple fruit— a good source of ascorbic acid (contains up to 75 mg/100 g), carotene and sugars.

The juice from the yellow variety (equated with Passiflora edulis f. flavi-carpa) contains lesser amounts of ascorbic acid and sugars.

The purple Passion fruit contains the C-glucoside, beta-ionyl-beta-D-glucopyranoside. A protease inhibitor (PEPI) has been isolated from the juice. PEPI inhibited trypsin and chy-motrypsin activities, but did not inhibit papain activity. The esters and terpenoids form the major part of fruit components. The terpenoids include a number of monoterpenes (including hydroxylated linalool derivatives), and monoterpene glycosides. Norter-penoid aglycones have also been found.

The yellow Passion fruit contains sulfur-containing volatiles, acetates, butanoates and hexanoates of 3-mer-captohexanol. The leaves contain C-glycosylflavonoids.
