Syzygium leuhmannii (F. Muell.) L.A.S. Johnson (commonly known as riberry). Syzygium is a large genus of evergreen flowering plants of the family Myrtaceae which consists of approximately 500 species.11 Plants of this genus are widespread, occurring in tropical and subtropical regions of South-East Asia, Australia and Africa. Many Syzygium species produce edible fruits and berries. S. leuhmannii is used to treat respiratory ailments, tuberculosis, gastrointestinal disorders, diarrhoea and dysentery.12 Recent reports have also highlighted the Australian Syzygium S. leuhmannii and Syzygium australe (Bush Cherry) extracts as having exceptionally high antioxidant contents.13 Antioxidants have been associated with the prevention of cancer, cardiovascular disease and neurological degenerative disorders.14-16 They are also linked with anti-diabetic bioactivities and have been associated with the reduction of obesity. Antioxidants can directly scavenge free radicals, protecting cells against oxidative stress related damage to proteins, lipids and nucleic acids.17 Thus, Syzygium spp. have potential in the treatment of a significant number of diseases and medical conditions related to cellular redox state. Many other Syzygium species internationally also have documented uses in traditional medicine.11 In the commercially most important species Syzygium aromaticum (clove), the unopened flower bud is used as a spice. This plant also has uses in traditional medicine due to its anaesthetic properties.18 The antibacterial activity of S. aromaticum is also well known. Numerous studies have reported on the antibacterial18 and antifungal19 activities of oils and extracts from this plant. Other Syzygium species from South East Asia (Syzygium jambos)20 and India (Syzygium lineare and Syzygium cumini)21 have also been shown to have antimicrobial activity. Recent studies have also reported the antibacterial activity of Syzygium cordatum leaf extracts. Of particular interest was the potent growth inhibitory of the extracts against the bacterial triggers of rheumatoid arthritis22 and ankylosing spondylitis.23
