Therapeutic potential of Leea indica (Vitaceae)

Background Leea indica (Burm. f.) Merr. (fam. Vitaceae), commonly known as ‘bandicoot berry’, is a Thai medicinal plant, and distributed widely in the far-east and south-east Asian countries, and in some parts of northern Australia. In Thailand, this plant has traditionally been used for the treatment of diarrhoea, pain, gastric ulcer, viral infections and some forms of cancers. Aims To review published findings on medicinal properties of L. indica and to critically appraise its therapeutic potential. Methods A comprehensive literature search was performed utilizing several databases, notably, Web of Science, PubMed and Google Scholar, and other relevant published materials. The keywords used in the search, individually as well as in combinations, were Leea indica, Vitaceae and traditional medicine. Results In vitro assays and in vivo animal studies displayed efficacy of the extracts and fractions of L. indica as an analgesic, antidiabetic, anti-inflammatory, antimicrobial, antioxidant and antiproliferative agent and indicated their therapeutic potential. Phytochemical studies revealed the presence of alkaloids, flavonoids, polyphenolics and terpenoids as major bioactive components in L. indica. Conclusion Preliminary bioactivity studies on L. indica provided some scientific basis for its traditional therapeutic applications. The presence of certain bioactive compounds in this plant could further support its therapeutic potential and traditional medicinal uses
