NATURAL OCCURRENCE OF MYCOFLORA AND DETERIORATION OF TOTAL ALKALOIDS AND GLYCOSIDES AMOUNTS IN STEREOSPERMUM CHELONOIDES DC. ROOTS UNDER STORAGE

In the present study, total 15 fungal species isolated from roots of drug Stereospermum chelonoides DC. such as: Fusarium solani, F. lateritum, F. semitectum, F. oxysporum, Aspergillus ochraceus, A. niger, A. terreus, Theilavia terricola, Papulaspora immerse, Scytallidium thermophilum, Didymostilbe sp., Cunningamella elegans, Aphanomyces sp., Sordaria fimicola and Mucor praini. Species of Fusarium showed maximum percentage incidence. The root samples stored at different relative humidities 30, 50, 75, 96 and 100% RH. Quantitative estimation of alkaloids and glycosides in association with isolated fungi was done. Percentage incidence of storage fungi and the rate of deterioration of chemical constituents in the samples were noted at above 75% RH. Analysis of variance also showed the effect of relative humidity and incubation days on biodeterioration of these chemical constituents were significant at 5% level of significance.
