Abstract

People have been using wild mushrooms in their diet and also as sources of income, but most of them do not have the proper knowledge to distinguish edible mushrooms from poisonous ones. The main objective of this research is to determine and document toxicity of some selected wild mushrooms of Nepal. Samples were collected based on their use practices by the local communities, representing different ecological belts. The tests were carried out following the protocol described in ‘Test Guideline no. 425: Acute Oral Toxicity: Up-and-Down Procedure’. Mice (Mus musculus) were administered with aqueous solution of each sample in a single dose by gavage using a stomach tube on the basis of their body weight and were observed for the signs of toxicity. The tested samples of Boletellus emodensis, Caloboletus calopus, Daedalea quercina, Lactifluus volemus, Lyophyllum decastes, Macrolepiota albuminosa, Phellodon niger, Phylloporus bellus, Russula delica, R. emetica, R. senecis, Strobilomyces strobilaceus, Termitomyces eurrhizus, T. le-testui, T. mammiformis, T. robustus, T. striatus f. brunneus, T. straitus f. pileatus, Trametes vernicipes and Trichaptum biforme revealed LD50 value > 2000 mg.kg-1 body weight indicating that they may be harmful if swallowed . However, in case of Hapalopilus rutilans, LD50 value of 1212 mg.kg-1 body weight was observed confirming that it is harmful when swallowed.
尼泊尔几种野生蘑菇的毒性试验
人们一直在饮食中使用野生蘑菇,也将其作为收入来源,但大多数人没有适当的知识来区分食用蘑菇和有毒的蘑菇。本研究的主要目的是确定和记录尼泊尔一些选定的野生蘑菇的毒性。代表不同生态带的当地社区根据其使用实践收集样本。试验按照“试验指南no. 5”中描述的方案进行。425:急性口服毒性:上下程序。小鼠(小家鼠)按体重用胃管灌胃给药,每次给药一次,观察毒性体征。检测样品中大黄带孢霉、大黄带孢霉、大黄带孢霉、白垩带孢霉、黑黄柏、bellloporus、Russula delica、吐乳霉、senecus、Strobilomyces strobilces、eurrhizomyces、le-testui、乳状霉、robustus、brunneus纹状霉、pileatus纹状霉、tremetes vernicipes和Trichaptum biformme的LD50值均> 2000 mg。体重1公斤,说明吞食后可能有害。然而,对于芦丁,LD50值为1212mg。经观察,体重为Kg-1,证实吞食有害。
