Fresh purple sweet potato (PSP) contains moisture 66.40%, crude protein 1.26%, crude fat 0.08%, ash 1.08%, crude fibre 1.10%, and total carbohydrate 30.08%. The biologically active compounds present in PSP sample (phytochemicals) are found in the screening test as; carbohydrate, glycoside, phenolic compound, anthocyanin, amino acid, saponin, flavonoid, reducing sugar and starch except alkaloid, tannin, steroid, terpenoid and cyanogenic glycoside which were totally absent in it.This paper mainly deals with the collection of PSP, the extraction of active compounds from the dried PSP powder, and qualitative analysis of phytochemicals in screening tests,as part of the research work of PSP wine production. The experimental data demonstrates that PSP present in Myanmar is one of the potential plant(tuber) for therapeutic use and provide health benefits for human.
