Abstract: Mango sudden death syndrome (MSDS) commonly known as Quick Decline Disease has been a threat to Mango production in the world. The present phytochemical study aimed to investigate the sugars in bark of healthy, adjacent to disease and diseased Mangifera indica (Mango) variety Langra. Ion exchange chromatographic technique showed presence of xylose, fructose, arabinose, glucose, lactose and an unidentified sugar in barks’ extracts. The non-uniform distribution of these sugars was supported by the quantitative analysis of sugar content in the samples. The results revealed the difference in total sugar content in healthy, adjacent to disease and diseased samples. Reducing sugars showed an interesting decrease in adjacent to disease samples while having a slight elevation in the diseased plant’s samples. The non-reducing sugars showed a steady decrease from healthy to diseased plant’s samples. Consequently, the present research showed sugars as markers in Mango Plant variety Langra in relation to Quick Decline.
