Embodiment 1

[0023] Cornus officinalis coarse powder is extracted with n-propanol aqueous solution with a volume ratio concentration of 70%, filtered, and the extract is concentrated under reduced pressure below 60°C until the alcohol content is 15% by volume; take HP- 20 macroporous adsorption resin column, then put the concentrated solution on the macroporous adsorption resin column, the flow rate of sample loading is 0.5BV / h; successively use 10BV deionized water, 30% n-propanol and volume ratio Concentration is that the n-propanol of 70% carries out gradient elution, and collects each eluate respectively, and the flow velocity of eluent is 0.5BV / h; The liquid was removed and concentrated under reduced pressure until alcohol-free, and the concentrated solution was spray-dried to obtain a hypoglycemic extract (yield 2.5%) and a liver-protecting extract (yield 0.8%), respectively.

Embodiment 2

[0026] Cornus officinalis coarse powder is extracted with ethanol aqueous solution with a volume ratio concentration of 85%, filtered, and the extract is concentrated under reduced pressure at a temperature lower than 60°C until the alcohol content is 20% by volume; Pore ​​adsorption resin column packing, then the concentrated solution on the macroporous adsorption resin column, the sample loading flow rate is 3BV / h; successively use 5BV deionized water, ethanol with a volume ratio concentration of 45%, and ethanol with a volume ratio concentration of 85%. Carry out gradient elution with ethanol, and collect each eluent separately, the flow rate of eluent is 3BV / h; Concentrate under reduced pressure respectively the 45% ethanol eluate, the 85% ethanol eluate, the concentrated solution adopts heating airflow Dry to obtain hypoglycemic extract (yield 2.7%) and hepatoprotective extract (yield 0.6%) respectively; deionized water eluted part is added back to cornus officinalis coars...

Embodiment 3

[0028] Cornus officinalis coarse powder is extracted with anhydrous methanol, filtered, and the extract is concentrated under reduced pressure at a temperature lower than 60°C until the alcohol content is 25% by volume; NAK-9 macroporous adsorption resin with 10 times the weight of cornus officinalis coarse powder is packed into a column, Then put the concentrated solution on the macroporous adsorption resin column, and the sample loading flow rate is 5BV / h; sequentially use 1BV of deionized water, methanol with a volume ratio concentration of 60%, and anhydrous methanol for gradient elution, and collect the eluted samples respectively. liquid; the flow rate of the eluent is 5BV / h; 60% methanol eluent and anhydrous methanol eluent are concentrated under reduced pressure respectively, and dried, and the concentrated solution is freeze-dried to obtain the hypoglycemic extract respectively (yield 2.3 %) and hepatoprotective extract (yield 0.7%); the deionized water eluate was adde...

Abstract

The invention discloses a method for preparing health-care foods with different activities by comprehensively using dogwoods. The invention relates to the comprehensive utilization technology of the dogwoods, relates to two dogberry extracts having hypoglycemic activities and liver protective effects and a dogberry jam having immunological enhancement effects and discloses a process for manufacturing the two dogberry extracts and the dogberry jam. The process comprises the following steps of: subjecting the dogwoods to extraction by lower alcohol; concentrating the extract; absorbing the extract by using a medium-polar or non-polar macroporous resin; eluting the absorbed product by using de-ionized water and lower alcohol at different concentrations; concentrating and drying the part of the absorbed product eluted by using the lower alcohol respectively to obtain a hypoglycemic extract and a liver protecting extract; and adding the part of the absorbed product eluted by using the de-ionized water into residues of dogberry medicinal materials to prepare the jam. The method can make full use of all parts of the dogwoods, and meanwhile, the customers have high pertinence on selection of the dogwood products.

Description

technical field [0001] The invention relates to the fields of substance extraction and traditional Chinese medicine health food, in particular to a method for comprehensively utilizing Cornus officinalis to prepare health food with different activities. Background technique [0002] Fructus Corni (Fructus Corni), a traditional Chinese medicine, is the dried pulp of Cornus officinalis Sieb.et Zucc., a plant of the Cornaceae family. Cornus officinalis is an important bulk Chinese herbal medicine, and has been included in the list of "both food and medicine" by the Ministry of Agriculture. In recent years, scholars at home and abroad have isolated a number of iridoid glycosides and triterpene acids from Cornus officinalis, mainly including loganin, morroniside, sweroside, Compounds such as ursonic acid and oleanolic acid have significant pharmacological effects and physiological activities. However, different parts of the compounds in Cornus officinalis have different pharmac...
