摘要

摘要对从印度瓜廖尔市各零售商随机采集的44份储藏干果样品进行了真菌污染水平分析。真菌学检查结果显示,97.77%的样品被不同种类的真菌污染。从三种水果样品中共分离到12种不同的真菌。获得的优势菌群分布在曲霉属、青霉属、互交菌属、根霉属和合头菌属5个属。其中曲霉属(71.95%)为最优势属,其次为青霉属(15.44%)、根霉属(9.51%)、杂交霉属(1.67%)和Syncephalastrum属(1.41%)。据报道,大多数已鉴定的真菌种类,如曲霉、青霉和交替菌,都能产生黄曲霉毒素、赭曲霉毒素、黄嘌呤和交替菌毒素等真菌毒素。储藏真菌的广泛存在表明,该霉菌可能在采收和采收后的加工过程中,即主要在干燥、储存、运输和加工过程中感染粗药材。根据目前的调查,可以得出的结论是,原材料的污染是惊人的,因为这些原材料需要彻底

Fungal Contamination Of few Common Stored herbal Fruit Samples
Abstract The levels of fungal contamination were analyzed in 44 stored dried fruit samples of Emblica officinalis (Alma), Terminalia bellirica (Baheda) and Treminalia chebula (Haritiki), randomly collected from various retailers from Gwalior city (India). As a result of mycological examination, 97.77% of the total samples examined, found to be contaminated with different fungi. A total of 12 different fungal species were isolated from all the three types of fruit samples of Emblica officinalis, Terminalia bellirica and Terminalia chebula . The predominant mycoflora obtained was distributed in five different genera comprised of Aspergillus, Penicillium, Alternaria, Rhizopus and Syncephalastrum. The Aspergillus (71.95%) was observed as the most dominant genera recovered followed by Penicillium (15.44%), Rhizopus (9.51%) , Alternaria (1.67%) and Syncephalastrum(1.41%). Most of the identified fungal species like Aspergillus, Penicillium and Alternaria are reported to have ability to produce mycotoxins like aflatoxins, ochratoxins, citrinine and alternaria toxins. The presence of a wide range of storage fungi indicates that the mould probably infects the crude herbal drugs during harvesting and post harvesting processing i.e. mainly during drying, storing, transportation and processing. On the basis of present investigations, it may be concluded that the contamination of raw materials is alarming, as these raw materials needs thorough
