Chios mastic, is the resinous secretion obtained from the wounds of the trunk and branches of Pistacia lentiscus L. var. Chia, which is endemic to the Greek island of Chios. Traditional usage of mastic dates back to more than 2500 years for gastrointestinal disorders [1]. More recently, mastic showed promising results in active Crohn's disease patients [2] as well as lipid- and glucose-lowering properties [3], antioxidant and anti-inflammatory properties [4]. In this work, 17 healthy volunteers were participated receiving per os a single dose of Chios mastic. Blood samples were collected at specific time intervals (e.g. 0, 1, 2, 4, 6 and 24 hours). After pretreatment plasma samples were analyzed by UHPLC-tQ-MS and the main constituents namely isomasticadienonic acid (IMNA) and masticadienonic acid (MNA) were directly quantified. MNA and IMNA are the most characteristic triterpenic acids of Chios mastic resin. Both compounds are not commercially available and have been isolated by an SFC-MS based method newly developed in house. MNA and IMNA were detected and Cmax plasma values were ranging from 29 to 768 ng/mL for IMNA and from 52 to 1390 ng/mL for MNA. Maximum concentration times were different depending on the subjects between 2 and 4 hours after intake. Moreover, oxidative stress markers in a postprandial phase were evaluated. Serum resistance time to oxidation increased after intake while the same trend was observed regarding the % change in oxLDL. This study offers for the first time information on the availability of bioactive components following ingestion of Chios mastic in humans together with evidence of its potency for oxidative stress reduction.
