Preparation method of andrographis paniculata freeze-dried preparation

Abstract

The invention provides a preparation method of an andrographis paniculata freeze-dried preparation, which comprises the following steps: carrying out reflux extraction on the andrographis paniculata medicinal material respectively with 20-times, 18-times and 18-times 60% ethanol for three times, 90 minutes per time; mixing the extracting solutions; recovering ethanol to prepare fluid extract; adding ethanol to enable the ethanol content to reach 80%; standing over night; filtering; adding 1% of active carbon into the filtrate; stirring for 30 minutes; filtering with a sterilized G4 filter element under aseptic conditions; recovering ethanol from the filtrate, and carrying out vacuum concentration until the crude drug content is about 3g / ml; adding a right amount of solubilizing agent and uniformly mixing; adding water for injection for metering volume until the crude drug content is 2g / ml; sub-packaging; freeze-drying; covering; labeling; and packaging to obtain the andrographis paniculata freeze-dried preparation. The freeze-dried preparation can be preserved in a vacuum state, so that the stability of effective components can be obviously increased and the shelf life of the product can be prolonged.

Problems solved by technology

However, due to the complex composition of traditional Chinese medicine injections and the presence of active ingredients in the liquid, polymerization reactions between different components will occur after long-term storage, which will affect the clarity, or cause other adverse reactions. In order to solve this problem, we invented a Chuanxinlian lyophilized preparation
