Syzygium polycephalum, locally known as lipote, is an indigenous Philippine tree. It was reported to lower high blood pressure and high cholesterol level and it exhibits antioxidant activity [1]. A recent study reported that a decoction of the bark is used for the treatment of dysentery [2]. There is no reported study on the chemical constituents of S. polycephalum. Syzygium cumini, locally known as duhat, is native to the Philippines and other Southeast Asian countries. It is marketed for its fruit, which is known for its hypoglycemic property. S. cumini possesses chemopreventive, radioprotective, and antineoplastic properties and is used in the treatment of diabetes mellitus, inflammation, ulcers, and diarrhea [3]. S. cumini extract was reported to exhibit antitumor and antioxidative potential against chemically induced stomach carcinogenesis [3]. Recently, a review of its food and medicinal uses was presented [4]. Syzygium samarangense, locally known as macopa, is native to the...
