Abstract
- OBJECTIVES: The aim of the current study was to assay the content of vitamin E in stinging nettle (Urtica simensis) METHODS: Urtica simensis type of stinging nettle is an indigenous wild plant which is widely growing in different parts of Ethiopia. Samples of leaves were collected from Chacha, one of the central highlands in Ethiopia and portioned into sun dried, shade dried and lyophilized groups. For comparison, samples of leaves were also taken from spinach. Vitamin E family such as tocopherols ((α, β, γ, and λ) and tocotrienols (α, β, γ, and λ) were determined using high performance liquid chromatography (HPLC) at department of Food Biofunctionality, University of Hohenheim, Stuttgart, Germany. RESULTS: The results showed that the total tocols of stinging nettle in sun-dried, shade dried, and lyophilized groups were 14.1 ± 1.1 mg, 13.8 ± 1.1 mg and 16.9 ± 1.2 mg per 100 g, respectively. In spinach, this value was 3.04 ± 0.7 mg/100 g. Of all vitamin E family, α- tocopherol was the maximum and identified in shade dried group (16.5 ± 1.2 mg/100 g). As compared to stinging nettle, spinach contained very small amount of α- tocopherol (1.7 ± 0.5 mg/100 g). CONCLUSIONS: In conclusion, Urtica simensis type of stinging nettle contains considerable amount of tocols and can serve as potential resource of vitamin E. Further research is warranted on the nutritional and medicinal values of Urtica simensis stinging nettle. FUNDING SOURCES: None.
