Chemical profile of the leaves of phymatodes scolopendria (giant polypody). – V. N.Osabor, F. I. Bassey and C. A. Edem
The leaves of phymatodes scolopendria was analysed for proximate, mineral, toxicant and phytochemical compositions. The proximate analysis showed that these leaves contained 20.40± 0.34% moisture, 14.00 ± 0.12% ash, 4.60 ± 46% crude lipid, 8.80 ± 0.10% crude fibre, 12.60 ± 0.20% crude protein, 68.80 ± 0.32% available carbohydrate and energy value of 366.8 ± 0.12 kcal/100g. Mineral composition revealed that some of the essential metals, such as zinc (23.34 ± 0.14mg/100g) and manganese (55.36 ± 0.54mg/100g) were high in concentrations and, the non-essential and toxic metals such as lead and cobalt were in trace amounts while; mercury (0.003 ± 0.11mg/100g) was very low. The toxicant composition of the leaves of phymatdoes scolopendria were relatively low especially phytic (1.34 ± 0.21mg/100g), and hydrocyanic acids (1.40 ± 0.12mg/100g). The results obtained from the phytochemical analysis revealed the presence of cardiac glycosides, tannins, flavonoids, polyphenols and reducing sugars in both water and petroleum ether extracts. The results obtained in this study have provided information on the nutritive value and its potential in ethno medicine applications.
