Enset (Ensete ventricosum (Welw.) Cheesman) is one of the oldest cultivated food security crops inEthiopia. There are a number of enset landraces used for traditional medicine. These landraces are believed to have better minerals and phytochemical compositions, which are not proved scientifically. The objective of this study was to compare the proximate, mineral and phytochemical compositions of corms of enset landraces used for treating bones illness traditionally, and two other landraces having another use value. Laboratory analysis was made by following standard methods, and the data determined were analyzed using SAS statistical software. Enset landraces, Kibnar and Guarye showed significantly (p < 0.05) higher protein content (4.74 and 4.06%), while Astara and Guarye were superior in phosphorus content (127.41 and 116.38 m g -2 ) respectively. Similarly, the highest zinc and tannin contents (8.52 and 153.94 m g -2 ) were obtained from Astara and Kibnar landraces respectively. On the other hand, Amerat landrace showed significantly (p < 0.05) higher crude fibre content. The three landraces used for traditional medicine showed better performances in protein, phosphorus, zinc and tannin contents than the other two landraces.

Background: Ethnic groups throughout the world have developed their own cultures expressed in the form of customs, taboos and traditional healthcare systems. Traditional medicine system is one of the widespread cultures known throughout the world which is very much tied to cultural practices of the community or ethnic group. Medicinal plant treasure found in Gurage and Silti Zones remained poorly characterized and understood. Therefore, this study was conducted in four ethnic groups: three from Gurage zone (Gurage, Qebena and Mareqo) and one from Silti zone (Silti) which have lived in close proximity and contact for many centuries in the respective Zones. In the present study unique and shared cultural elements in connection to traditional herbal medicine were examined through investigation of the diversity of medicinal plants. Moreover, attempts have been made to determine similarities among the society in the medicinal plants they have used in general and in medicinal plant species considered culturally most important.Methods: In a study that involved 320 randomly sampled informants semi-structured interviews, focus group discussions, participant observation were used and qualitative and quantitative data were collected. Descriptive statistics, rank order priority (ROP), informant consensus factor, jaccard similarity coefficient and clustering were used for data analysis. Results: A total of 244 medicinal plant species and a fungal species used to treat human and/or livestock ailments were documented. The number of plants (80 plants, 33 %) with ROP value greater than 50% is considerably smaller than that of plants with ROP < 50% (164, 67 %). Jaccard similarity index and clustering analysis for all cited plants, among the respective studied districts, indicated that grouping generally followed the existing ethnic origin. On the contrary, clustering based on culturally important medicinal plant species (80 plant species, score ROP ≥ 50%) showed the influence of proximity and geographical orientation rather than ethnic relation. Conclusions: Culturally most important plants (80 spp.) are widely used and best shared with nearby communities and this could imply current (new) knowledge being practiced in the community. This knowledge must be documented and better utilized in a modern way including modernized use of traditional medicinal plants.

Wild edible plants (WEPs) are the natural food source that can help to mitigate food insecurity and improve starvation in low income countries including Ethiopia. Despite the widespread use of WEPs in Ethiopia, studies on the nutritional contents of Ethiopian WEPs are limited. The objective of the current study is to evaluate the nutritional value (proximate, mineral, and vitamin C contents) of the most consumed seven wild edible plants collected from Lasta District, Northeastern Ethiopia. The nutritional parameters including proximate, macro and micronutrients, and also vitamin C contents of the selected seven wild edible plants were evaluated using standard food analysis methods (moisture by dry-oven method, ash by high-temperature incineration in an electric muffle furnace, fat by Soxhlet extraction procedure, protein by Kjeldahl process, minerals by Atomic absorption spectrometer and atomic emission spectrometry and vitamin C by using a spectrophotometer). One-way ANOVA was used to analyze the nutritional content variations of selected WEPs. The proximate composition of the 7 WEPs came in the respective ranges of moisture (6.50–9.77 g/100 g); ash (6.99–26.35 g/100 g); crude protein (13.1–33.63 g/100 g); crude fat (1.08–9.83 g/100 g); crude fiber (6.21–43.77 g/100 g); utilizable carbohydrate (30.11–66.25 g/100 g) and gross energy (213.05–414.80 Kcal/100 g). The mineral composition of WEPs (mg/100 g dry weight) for macronutrients ranged from 25.53–37.99 Na, 56.65–72.79 Mg, 14.40–43.57 K, 44.35–60.14 Ca, and for micronutrients it ranged from 10.51–27.96 Fe, 8.35–23.87 Zn, 14.08–23.20 Cu, and 7.99–19.08 Mn. The vitamin C contents of WEPs (mg/100 g dry weight) ranged from 2.16–70.42 except in Haplocarpha rueppelii leaves in which its vitamin C content is below the detection limit. The outcome of the investigation indicates that the proximate, mineral and vitamin C contents of the WEPs included in the analysis were higher than those of some common crops (sorghum, rice, wheat, barley and maize), indicating their nutritional contribution to the human diet in the studied area. These wild food sources make up a good part of the traditional subsistence system of the people of Lasta District alongside their common food crops and other food sources.
