Problems solved by technology

This methanol crude extract has not been separated and purified, has high impurity content, low active ingredient content, deep color, strong hygroscopicity, difficult preservation, and poor processing adaptability
At the same time, the variety of plum tree used is not clear. When the extract is used in the field of medicine, if the source of the plant is not sure, the three basic requirements of drug effectiveness, safety and stability cannot be guaranteed.

[0082] Preparation method of plum tree extract

[0083] The plum tree extract provided by the present invention can come from the whole plum tree, preferably the non-fruit part thereof. Said non-fruit parts include flowers, branches, stems, roots, or leaves. Plum blossoms are mainly taken from unfruited flowers, which are hand-picked and dried in the sun, fried or dried for later use; plum branches can be pruned vegetative branches in spring, pruned branches in autumn, or the branches of plum trees cut down and dried in the sun. , cut and broken for later use; plum leaves are generally collected in summer and autumn and dried in the sun for later use; plum stems and plum roots come from felled plum trees.

[0084] The plum tree raw material that the present invention adopts can carry out pretreatment, also can not through pretreatment. The preferred raw material is 10-20 mesh chips with a water content below 10%.

[0085] The plum tree extract containing 0.5-50% squalene pr...

Abstract

The invention discloses a plum extract containing 0.5-50wt% of squalene. The plum extract mainly comes from liposoluble effective parts and / or water-soluble effective parts from non-fruit part of plum. The invention also provides the preparation method of the plum extract, Liposoluble effective part is obtained through extracting of super-criticality CO2 fluid or nonpolarity organic solvent; the residue of the super-criticality fluid or nonpolarity solvent extract is extracted by alcohol-water solution to obtain the water-soluble effective part. The invention discloses the composition containing plum extract and also discloses application of the plum extract.

Description

technical field [0001] The present invention relates to the field of plant extracts. More specifically, it relates to effective parts extracted from non-fruit parts (flowers, branches, leaves) of plum trees, their preparation methods and uses. Background technique [0002] Plum is a plant of the genus Prunus in the family Rosaceae (Rosaceae), and its scientific name is Prunus mume Sieb.Et Zucc. In horticultural cultivation, plum is divided into flower plum and fruit plum, and fruit plum is divided into white plum, green plum and red plum. [0003] WO00 / 39249 (PCT / JP99 / 07285) discloses a medicinal plum extract and a composition containing the extract, which discloses the following content: "Using 5 times the volume of methanol, from the stems and leaves of plum The extract is prepared from the nuts and plum blossoms of plum, plum, and has antioxidative effect, gastric mucosal damage inhibitory effect, aldose reductase inhibitory effect, blood sugar level rise inhibitory effe...
