Oleuropein (OE), the main polyphenol in olive leaf extract, is likely to decompose into hydroxytyrosol (HT) and elenolic acid under the action of light, acid, base, high temperature. In the enzymatic process, the content of OE in olive leaf extract and enzyme are key factors that affect the yield of HT. A selective enzyme was screened from among 10 enzymes with a high OE degradation rate. A sin...

experiments were carried out in a commercial orchard during 1994, 1995 and 1996 to determine the influence of chemical thinning on characterisics of fruit and alternate bearing of native olive (olea europea l) cvs. dezfoul and fishomi at early fruitlet stage. in 1994, branch sprays of naphthalene acetic acid (100, 150 and 200 mg/l), naphthalene acetamide (200 and 300 mg/l) and urea (0.6 and 1.2...

Olea europaea L. is used in traditional medicine in the Mediterranean areas. Its natural products are used in the treatment of different disorders, like fighting fever and some infectious diseases such as malaria, the treatment of arrhythmia, and relief of intestinal spasms. The aim of the current study is to investigate the possible anti-inflammatory and anatinociceptive effects of methanol an...

BACKGROUND Medicinal plants are possible sources for future novel antioxidant compounds in food and pharmaceutical formulations. Recent attention on medicinal plants emanates from their long historical utilisation in folk medicine as well as their prophylactic properties. However, there is a dearth of scientific data on the efficacy and stability of the bioactive chemical constituents in medici...
