Nutritional Analysis of Morchella conica and its Role on Rural Livelihood

The study on nutritional value of locally preferred fodder trees in the farmland of middle hills of Nepal was conducted in Hemja VDC of Kaski district. Primary information on distribution and frequency of fodder trees was obtained through key informants survey, group discussion and observation of the study area. The preference ranking of ten most abundant fodder trees was done on the basis of palatability, propagation easiness, growth rate and competition with agricultural crops. The nutritional value of fodder species was analyzed and compared with the farmers' preference ranking to examine association among them. The analysis correspond farmers' preference of fodder tree species to their nutritional values. The study revealed that Ficus subinisa was the dominant fodder tree however, the Artocarpus lakoocha was highly preferred trees for its palatability and nourishing values. Nutritional analysis of ten preferred fodder species with respect to moisture, ash, crude protein, crude fat, crude fiber and carbohydrate was carried out. The crude protein varied from 15-29%, in which, A. lakoocha to contained the highest amount of crude protein. Similarly, F. lacor contained highest crude fiber (42.07%), and Machilus odoratissima yielded highest amount of carbohydrate (21.92%).

27The current research work is focused on screening of antimicrobial, antioxidant, total phenolic, 28 total flavonoid, metal estimation and proximate potential of four parts (fruits, leaves, stem bark 29 and root bark) of S. xanthocarpum. Antimicrobial potential of dried crude extracts of S. 30 xanthocarpum were evaluated against two gram positive bacteria (S. aureus, P. vulgaris), three 31 gram negative bacteria (P. aeruginosa, K. pneumonia, E. coli), three fungi (A. flavus, F. solani, 32 R. stolonifer) and two yeasts (S. cerevisiae, C. albicans) by using disc diffusion assay. Five 33 organic solvents ranging from non-polar to highly polar were used for extraction of active 34 metabolites. Amongst all the parts of S. xanthocarpum tested, antimicrobial activity of methanol 35 extract of fruits (14.67±0.33) against P. aeruginosa, ethanolic extract of leaves against P. 36 vulgaris (14±0.58), stem bark methanolic extract against S. aureus (13±0.58) and stem bark 37 methanolic extract against P. vulgaris (17.67±0.33) were found to be more significant. All other 38 extracts also showed promising antimicrobial activity against bacterial pathogens. Among fungal 39 pathogens, R. stolonifer and S. cerevisiae were found to be more sensitive to extracts of S. 40 xanthocarpum. Gram negative bacteria exhibited more resistance than gram positive bacteria. 41However, fungi were found to be more resistant than bacteria. All the extracts showed 42 antioxidant activity. However, methanol extract of stem bark of S. xanthocarpum with IC 50 value 43 of 0.323102 mg mL -1 showed maximum antioxidant potential. Total phenolic contents ranged 44 from 12.3541±1.73 to 23.2942±1.33 Pmol GA/ug. However, highest flavonoid content was 45 found in the stem bark extract (17.8480±1.75 ugRutin/ug) and lowest in leaves extract of S.46 xanthocarpum (2.4806±0.59 ugRutin/ug). Total metal contamination in four parts of Solanum 47 xanthocarpum (fruits, leaves, stem bark and root bark) was estimated by atomic absorption 48 spectroscopy and results showed Cadmium contamination in its stem bark and root bark, 3 49 Chromium contamination in leaves, stem bark and root bark, Copper and Magnesium 50 contamination in all parts of S. xanthocarpum and Maganese contamination in leaves critically 51 above the standard permissible limits. The proximate analysis of the Solanum xanthocarpum 52revealed that stem bark is a poor source of lipid (3.42%) and high carbohydrate (50.07%) and ash 53 (16.50%) contents. Whereas, root bark has highest wet moisture content (65%), dry moisture 54 content (20%) and lowest fiber (13%). Highest energy (285.455%), protein (8.32%), fat (9.79%) 55 and lowest amount of ash (13%) was found in fruits. This composition shows that the Solanum 56 xanthocarpum could be considered as a good source of carbohydrate, moisture and energy. 57 These results revealed that over all, methanolic extract of the S. xanthocarpum is richest in 58 phenolic, flavonoid and nutritional contents as well as most potent against bacterial and fungal 59 path...

In Nepal morel mushroom is one of the most important wild edible fungi, which is exported, in larger quantities.They have been collected, consumed and traded for more than two decades. The morel mushroom trade is worth a multi-billion dollar industry worldwide. This study was carried out to elucidate the current harvest and trade of morel mushrooms, the prospects for commercial morel industry development and the resource management in Nepal. Wild morels are harvested commercially and exported extensively from west Nepal especially from Karnali and Far West Province which share 58% and 29% of total national output respectively. Most commonly found and traded species are Morchella conica and M. esculenta. In most cases, the collectors sell morels in fresh form to the local dealers or in the local markets from where they are exported to different parts of the world. A bulk of morel mushrooms is traded via Nepalgunj and Mahendranagar routes. The local collectors get nominal benefits as prices are very low in the local area as compared to international markets. The price of M. conica is always higher than other morel species. There is neither processing nor any kind of value addition works currently being done in Nepal except drying, grading and packaging. The present study reveals that Nepal has a huge potential to become a major global producer of high quality morels. There is no serious concern about the overexploitation of the resource at the moment. However, a reliable local monitoring system and a scientific intervention for the artificial cultivation are inevitable for the sustainable management.
