Objective To study the material basis of the anti-diabetic effective fraction in the leaves of Olea europaea. Methods Preparative medium pressure liquid chromatography (PMPLC) was used for the separation and purification of the compounds. Their structures were elucidated by spectral analyses. Results The structures of the compounds were identified by various spectroscopic methods combined with the data from some published literatures. There were five compounds which were extracted from the anti-diabetic effective fraction in the leaves of O. europaea and identified as decaffeoylverbascoside (1), luteolin-7-O-β-D-glucoside(2), 6″-O-β-D-glucopyranosyl oleuropein (3), oleuroside (4), and oleuropein (5). Additionally, decaffeoylverbascoside is isolated from this plant for the first time and the purities of the five compounds were all above 90% by HPLC detection. Conclusion This research provides technological support for the development of new drug based on the leaves of O. europaea. |
