Abstract

A physico-chemical and phytochemical characterisation of the oil of two rich sources of polyunsaturated fatty acids, tocopherols and phytosterols is presented for two close species of Plukenetia, endemic to the Amazon Region of Peru. Plukenetia huayllabambana presented approximately 9% more oil yield than Plukenetia volubilis. Fatty acid profiles were pretty similar for both species but P. huayllabambana presented a significantly higher content of α-linolenic acid than P. volubilis (51.3 and 45.6 g/100 g oil, respectively). Important contents of γ- and δ-tocopherol were evidenced in both oils (127.6 and 84.0 and, 93.3 and 47.5 mg/100 g oil, for P. volubilis and P. huayllabambana, respectively). β-Sitosterol was the most important and representative phytosterol in both oils (∼127 mg/100 g oil). The results of this study indicate P. huayllabambana as an important dietary source of health promoting phytochemicals.
