Characteristics, Isolation Methods, and Biological Properties of Aucubin.

Aucubin is an iridoid glycoside widely spread in the families , , , , , , , and . This review is intended to provide data on the physicochemical characteristics, isolation methods, and biological activities of aucubin and its producing plants. Aucubin is unstable and can be deglycosylated into its aglycone, aucubigenin.

A green extraction design for enhancing flavonoid compounds from flowers using a deep eutectic solvent.

In this study, an environmentally friendly extraction method for flavonoid compound from , as a new raw material candidate for herbal medicine and cosmetics, was developed. The objectives of the present work were to provide recommendations for the optimal extraction conditions and to investigate the effects of any extraction parameters on flavonoid yields from the flower. The extraction process was performed using deep eutectic solvent (DES) (choline chloride and propylene glycol at molar ratio of 1 : 1) and the ultrasound-assisted extraction method.
