ABSTRACT
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.
