Abstract

The invention provides a method for extracting hydroxytyrosol from syringa oblata. By means of hydrolytic in-situ extraction, ester bonds in oleuropein can be hydrolyzed totally and transformed into free hydroxytyrosol, so that content of hydroxytyrosol in extract liquor is increased, wherein OH-ion exchange resin serves as a catalyst to promote hydrolysis of oleuropein, and a chlorinated solventserves as an extracting agent to extract free hydroxytyrosol. Therefore, in the hydrolytic in-situ extraction process, hydrolysis of oleuropein and extraction of free hydroxytyrosol are completed simultaneously. Meanwhile, with adoption of the hydrolytic in-situ extraction, complicated two steps of operation for hydrolysis and extraction are avoided effectively, operation procedures and solvent dosage are reduced, production cost is low, and yield of hydroxytyrosol is high.

Description

technical field

[0001] The invention relates to the technical field of compound extraction, in particular to a method for extracting hydroxytyrosol from lilac. Background technique

[0002] Lilac is a deciduous shrub or small tree, often planted as an ornamental plant, with a wide geographical distribution, from Inner Mongolia in the north, to Yunnan in the south, to Heilongjiang in the east, to Sichuan and Tibet in the west, and has been widely distributed in China. It has been cultivated for many years and is also a commonly used medicinal material among the people. Lilac stems contain several antioxidant active compounds such as: syringin, oleuropein, and hydroxytyrosol.

[0003] Hydroxytyrosol is a natural polyphenolic compound with a variety of biological and pharmacological activities, such as: it has a good effect on the treatment of cancer, cardiovascular disease, neurodegenerative disease, diabetes, inflammatory infection and anti-oxidation , especially its antiox...
