Origin and geographic distribution
Cyclanthera pedata is a native of Andean South America, but now only known in cultivation or as an escape. It is cultivated from Mexico to Peru and Ecuador and also in the Old World tropics. In Africa cultivation is restricted to highlands of East Africa.
Young fruits are eaten raw or pickled. Older fruits are eaten after removal of the seeds and boiling. The taste is similar to that of cucumber. Young shoots and leaves are eaten as greens. Cyclanthera pedata has the reputation of being anti-inflammatory, hypocholesterolaemic and hypoglycaemic. An extract of the fruit is marketed under the name Cycladol.
The fruit contains per 100 g: water 94 g, protein 0.6 g, fat 0.1 g, carbohydrate 4 g, fibre 0.7 g, Ca 14 mg, P 14 mg, Fe 0.8 mg, thiamin 0.04 mg, riboflavin 0.04 mg, niacin 0.3 mg, ascorbic acid 14 mg (Rubatzky & Yamaguchi, 1997).
Investigations into the chemical constituents of Cyclanthera pedata seeds and fruits have revealed the presence of 6 flavon glycosides, 9 triterpenoid saponins and 6 cucurbitacin glycosides.
Annual, monoecious vigorous vine; stem up to 5 m long, glabrous; tendrils bifid. Leaves alternate, palmately 3–5-foliolate or simple but very deeply lobed; stipules absent; petiole 1–8 cm long; leaflets or lobes elliptical, sinuate-serrate. Flowers unisexual, regular, 5-merous; male flowers in axillary, 10–20 cm long panicles; female flowers solitary, with inferior, 1-celled ovary. Fruit an indehiscent, obliquely ovoid berry up to 16 cm long, tapering, flattened, white-green, sometimes with soft spines, many-seeded. Seeds c. 1.5 cm in diameter, black.
Cyclanthera is placed in Cyclanthereae, an entirely New World tribe. Cyclanthera brachystachya (Ser.) Cogn. (synonym: Cyclanthera explodens Naudin, called ‘fat baby’) is cultivated locally in Cameroon at altitudes of 1500–2000 m as a fruit vegetable. It differs notably from Cyclanthera pedata in its explosively dehiscent, small fruits (2–4 cm long).
Cyclanthera pedata is fairly tolerant of cold and cultivated in the tropics at altitudes of 2000–3000 m.
Propagation is by seed. Plants are spaced at 90 cm × 90 cm. They have to be staked. Fruits are harvested from about 3 months after planting. Plants usually remain productive with abundant fruiting for several months. Harvesting is preferably done when the fruits are full-sized but still immature.
Genetic resources and breeding
Interest in Cyclanthera pedata is mainly in the Americas and India, where commercial cultivars are marketed.
In highland areas in tropical Africa Cyclanthera pedata certainly has a future as a vegetable crop. Products based on a fruit extract are marketed in the United States and western Europe as a herbal medicine against high cholesterol levels, and demand might well increase.
