Embodiment 1

[0021] Embodiment 1--the preparation method of Ligustrum lucidum glucoside enrichment

[0022] like figure 1 As shown, 3kg of Ligustrum lucidum plus 12 times the volume concentration of 70% ethanol, reflux extraction for 1.5h, filtered, plus 8 times the volume concentration of 70% ethanol for the dregs, reflux extraction for 1.5h, filtered, Combine the two filtrates, recover the solvent to 3L, add ethyl acetate to extract twice, 3L each time, discard the ethyl acetate layer, add water-saturated n-butanol to extract 3 times, each time 3L, combine the water-saturated n-butanol layer , concentrated, and vacuum-dried to obtain the glucoside enrichment of Ligustrum lucidum, which is used for subsequent test examples.

Embodiment 2

[0023] Embodiment 2--other preparations of Ligustrum lucidum glycoside enrichment

[0024] The values ​​of the three factors of ethanol concentration, volume, and reflux time in Example 1 were adjusted and combined (as shown in Table 1 below), and other preparation methods were kept unchanged to obtain Ligustrum lucidum glycoside enrichment A-H.

Abstract

The invention discloses a ligustrum lucidum glucoside concentrate and an application thereof. A preparation method of the ligustrum lucidum glucoside concentrate has the following steps: adding 10-14times amount of ethanol having a volume concentration of 50-80% into ligustrum lucidum, performing reflux extraction for 1-3 h, filtering, adding 8 times amount of the ethanol having a volume concentration of 50-80% into medicine residues, performing reflux extraction for 1-3 h, filtering, combining two filtrates, recovering solvents, adding appropriate amount of ethyl acetate for extraction, discharging an ethyl acetate layer, adding water-saturated n-butanol into a water layer for extraction, combining a water-saturated n-butanol layer, condensing, and performing vacuum drying to prepare theligustrum lucidum glucoside concentrate. The invention also discloses an application of the ligustrum lucidum glucoside concentrate in preparation of medicine for treating hypoparathyroidism.

Description

technical field [0001] The present invention relates to a glycoside-enriched product of Ligustrum lucidum, and furthermore, the invention also relates to the medical application of the above-mentioned glycoside-enriched product of Ligustrum lucidum. Background technique [0002] Hypoparathyroidism (hypoparathyroidism) is abnormal calcium and phosphorus metabolism caused by decreased secretion and / or dysfunction of parathyroid hormone (PTH). Once it occurs, it will seriously affect the quality of life of patients. Parathyroid injury or missection caused by neck surgery is the most common cause of secondary hypoparathyroidism. The larger the extent of thyroidectomy, the higher the incidence of hypoparathyroidism. When parathyroid hypocalcemia occurs, neuromuscular excitability increases, muscle spasms, tetany and convulsions may occur, and severe cases are life-threatening; bone calcium deficiency is manifested as osteomalacia and loosening; the membrane barrier effect on ion...
