Regular consumption of fruit and vegetables is associated with a lower risk of some chronic diseasesincluding various forms of cancer and cardiovascular diseases. The health-promoting potential ofthese foods may be due, in part, to the phytochemical bioactive compounds present in the plants.Fruit of Euphoria longana Lam. (longan) are consumed throughout Asia and are a major crop inThailand. In the present study phytochemicals were extracted with 70% methanol from peel, pulp,and seed tissues of longan fruit, and the major components were identified as gallic acid, corilagin(an ellagitannin), and ellagic acid. A high-through-put reversed phase HPLC method was developedto determine the content of these three compounds in different parts of the longan fruit and amongdifferent cultivars. The analyses showed that there was a large variation in the contents of gallicacid, corilagin, and ellagic acid in different plant tissues and cultivars. Seed contained the highestlevels of the three phenolics, and pulp contained the lowest. Among commercial cultivars, Biewkiewand Edor contained the highest levels of gallic and ellagic acid while Srichompoo contained the highestcontent of corilagin. These three cultivars may be used in directed breeding and cultivation programsand to develop concentrated longan seed extracts to promote good health. Utilization of this byproductmaterial will support the use of thousands of tons of waste longan seeds after the production ofcanned longan pulp.
