Embodiment 1

[0017] Black pepper extract was prepared by carbon dioxide supercritical fluid extraction.

[0018] Take 100g of black pepper, crush it appropriately, pass through a 60-mesh sieve, put it into an extraction kettle, and under appropriate extraction conditions (extraction pressure 30MPa, temperature 60°C, entrainer is 95% ethanol, entrainer dosage 1:0.5 w / v ) was continuously extracted for 2 hours, and the effluent in the separation tank was dried under reduced pressure to obtain black pepper extract. The yield calculated by weighing is 7.7%. Through HPLC assay, the content of piperine in this black pepper extract is 68.9%, see attached figure 1 . (For HPLC content determination conditions, see the 2010 edition of "Chinese Pharmacopoeia", P227)

Embodiment 2

[0020] White pepper extract was prepared by ethanol reflux extraction.

[0021] Take 100g of white pepper, crush it properly, pass through a 60-mesh sieve, put it into a 2000ml round bottom flask, add 1000ml of 75% ethanol to it, and extract 3 times, each time for 1 hour. The extracts were combined, concentrated under reduced pressure, and dried to obtain the white pepper extract. The calculated yield by weighing is 18.3%. Through HPLC assay, the content of piperine in this white pepper extract is 22.9%, see attached figure 1 . (For HPLC content determination conditions, see the 2010 edition of "Chinese Pharmacopoeia", P227)

Embodiment 3

[0023] Effect of black pepper extract on sleep duration induced by sodium pentobarbital in mice.

[0024] Experimental materials: Kunming mice, ♂, weighing 21±3 grams (provided by the Experimental Animal Center of Shenyang Pharmaceutical University).

[0025] Drugs: Polysorbate-80 (Shanghai Dazhong Pharmaceutical Factory); Pentobarbital Sodium (Beijing Second Pharmaceutical Factory). Black pepper extract (33.2% piperine content as determined by HPLC) was prepared as a suspension using 2% polysorbate-80.

[0026] Test method: Mice were divided into 4 groups, 10 in each group, and 2% polysorbate-80, black pepper extract 1.0, 2.0 and 4.0 mg·kg were administered orally, respectively. -1 1.0 hours later, intraperitoneal injection of pentobarbital sodium 45mg·kg -1 , observed the disappearance and recovery time of righting reflex in mice, and calculated the duration of sleep. The results showed that black pepper extract could significantly prolong the sleep time of mice induced by...

Abstract

The invention belongs to the technical field of medicines and discloses novel application of pepper extractives in sedative-hypnotic. The pepper extractives use fruits or seeds of pepper plants as raw materials, and by means of a method of carbon dioxide supercritical fluid extraction or water extraction or ethanol extraction, the pepper extractives are obtained. By means of analysis and experimental verification of righting reflex experiments of mice and sleep time phase of rabbits, the pepper extractives have a good function of sedative-hypnotic, can be used in the development of sedative hypnotic Chinese medicines and natural medicines, and can also be used in the development of the health foods with effects of promoting sleep.

Description

technical field [0001] The invention relates to the application of pepper extract in the preparation of sedative and hypnotic drugs and health food with the effect of promoting sleep, and belongs to the field of traditional Chinese medicine and health food. Background technique [0002] Pepper is a plant belonging to the family Piperaceae, Pepper ( Piper nigrum L.) fruit. The fruits and seeds of pepper can be processed in different ways to obtain black pepper, white pepper, green pepper and red pepper. When the fruit at the base of the ear starts to turn red, cut off the ear, and after drying or drying, it becomes dark brown, and the fruit is removed, commonly known as black pepper. If all the fruits have turned red, they are harvested, soaked in water for several days, wiped off the exocarp, and dried in the sun, the surface will be grayish white, commonly known as white pepper. 80%~85% of the total pepper consumption in the world is black pepper, 15%~20% is white peppe...
