Ecology:
Near sea level to 900 m. Usually grows in open forest but occasionally found in monsoon forest and also in or on the margins of lowland rain forest.
Chemical and Pharmacology:
The moisture, ash, Crude lipids, crude protein and carbohydrates analysis were determined. Anti-nutritional factors like phytate, oxalate, cyanogenic glycosides and saponins were also determined. Results of the analysis indicate the moisture content to be 18.58, 15.40 and 28.38% for samples A, B and C, respectively. Ash content of the peels was found to be 4.13, 9.60 and 5.13% for samples A, B and C, respectively. Lipids content of the samples was found to be 3.80, 2.85 and 1.10% for A, B and C, respectively. The amount of fibre in sample A, B and C was found to be 2.06, 2.07 and 1.10%, respectively while 0.21, 00.07 and 00.18% was obtained as the protein content of the peels, respectively. The result of carbohydrates was found to be 71.20, 69.35 and 62.94 for the three samples, respectively. Results of anti-nutrition indicate the levels of Cyanogenic glycoside to be high (45.00, 43.00 and 44.00 mg kg-1). Saponin content of the peels was found to be 35.00, 31.50 and 34.50 mg kg-1. Phytate in the sample to range between 28.50-29.50 mg kg-1, while Haemogglutinin and oxalate were found to be 20.00-23.00, 16.50, 19.00 and 15.50 mg kg-1 for samples A, B and C, respectively. Tacca leontopetaloides peels though has high content of carbohydrates, it is not suitable for consumption because of the high anti-nutritional factors.
Cultivation:
Uses:
Edible Plant Parts (Edible Stems)
Food (Fruit & Vegetable : The tubers are edible after proper cooking, and are a good source of starch.)
[Others]: The plant is cultivated as an ornamental shrub for its leaves and attractive flowering shoot. The stems are used to manufacture hats as they make good braiding material.
