| Abstract: | Hydroxytyrosol was extracted from 5 breeds of olive leaves from different tree ages by ultrasonic extraction using 90 % MeOH-H2O and analyzed by HPLC method.Simultaneously,the conversion trend of oleuropein into hydroxytyrosol was investigated from 10 breeds of olive leaves stored over 3 years.Results showed that:content of hydroxytyrosol in a growing year has one high peak period namely May and Jun.,and one low trough period,namely Nov.and Dec..Huge differences existed among different breeds.The content of... |
