This review deals with the literatures on Syzygium species (family: Myrtaceae). It was mentioned as a source of traditional
medicine to treat diabetes mellitus. However, due to the lacking information on Syzygium cumini, its potential benefit is still
unknown among the local. This plant, commonly known as black plum, is a plant native to India. Studies from abroad showed
that S. cumini is rich in anthocyanins, which could contribute to its pharmacological properties. Various extracts from different
parts of S. cumini were reported for its antidiabetic, antimicrobial, antibacterial, antivirus, antifungal, antiinflammatory and
antidiarrheal activities. In this research, organic solvent extractions are performed on the local S. cumini. The methodologies
also include thin layer chromatography and phytochemical screening, in identifying the phytochemicals. In summary, it is
expected that alkaloids are the component of the leaves extract.
