This study was carried out in order to determine some biochemical characteristics, phenolic compounds and antioxidant activity in fruits of cherry laurel genotypes (Laurocerasus officinalis R.) grown in Sakarya province of Turkey. In this study, previously selected fifteen promising genotypes were examined. The cluster weight was changed between 21.60–109.27 g and fruit numbers of per cluster 19.00–27.00. The average fruit weight ranged from 1.08 to 5.33 g, fruit length ranged from 12.09 to 20.95 mm and fruit width ranged from 10.58 mm to 21.94 mm among the studied genotypes, respectively. Fruit dry matter contents were changed between 16.62–25–49%, titratable acid content (TAc) 0.22–0.49%; fruit juice pH value 4.43–4.93; nitrogen content 0.11–0.37%, crude protein content 0.67–2.31%, soluble solid contents (SSC) 15.53–31.36%, refractive index 1.356–1.385 and ash contents 0.237–0.720%, respectively. Total phenolic content was found between 11.97–47.41 mg GAE/g dry weight basis and antioxidant activity 3.36–25.10% among the genotypes. The results obtained suggest that genotypes searched have promising potential both for production and human health.
