[0019] Experimental Study on the Technical Conditions of Extracting the Volatile Oil of Houttuynia cordata

[0020] ①Inspection of water absorption

[0021] Herbal medicinal materials have varying degrees of ability to absorb solvents, and the amount of solvent absorbed will affect the extraction effect. Therefore, the water absorption rate of fresh Houttuynia cordata was investigated.

[0022] Take Houttuynia cordata 1000g, add 2 times the amount of water, and soak for 1 hour. Filter, weigh medicinal materials, weigh 1150g, then the water absorption rate is:

[0023] 1150 - 1000 1000 × 100 % = 15 %

[0024] Houttuynia cordata is a fresh medicinal material, and its water absorption rate is low and negligible.

[0025] ②Influence of the amount of water added on the amount of volatile oil collected

[0026] There are three grou...

Abstract

The present invention provides a medicine composition for curing upper respiratory tract infection. It is a preparation made up by using houttuynia volatile oil as active component, adding proper auxiliary components through a certain preparation process. In the houttuynia volative oil the methyl-n-nonylketone is contained. Said preparation can be made into various dosage forms, including injection and oral preparation.

Description

technical field [0001] The invention relates to a pharmaceutical composition for treating upper respiratory tract infection, in particular, a pharmaceutical composition prepared by taking the volatile oil of traditional Chinese medicine Houttuynia cordata as an active ingredient. Background technique [0002] Houttuynia cordata Thunb. is a perennial herb that can be used as medicine and food. The main active ingredient is houttuyninum in volatile oil. Has strong antibacterial and antiviral effects. More reports are made on the chemical constituents of Houttuynia cordata at present, such as: the chemical constituents of Houttuynia cordata volatile oil, Journal of Plant Resources and Environment, 2003, 12 (3), reported the method (water Steam distillation method, organic solvent extraction method, supercritical CO2 extraction, the contents of the index components measured by various methods are different, and the methods of evaluating the quality are also different. Recent re...
