| titleOfInvention | Preparation method of Chinese herbal medicine active ingredient nano material |
| abstract | The invention relates to a preparation method of a Chinese herbal medicine active ingredient nano material, which comprises the following steps: (1) pulverizing herba Houttuyniae and flos Lonicerae, mixing, adding appropriate amount of ammonia water, soaking for 0.5-1 hr, adding 50-70% ethanol solution, reflux extracting for 6-8 hr, cooling to room temperature, filtering, and concentrating the filtrate under reduced pressure to obtain crude extract; (2) adding an ethanol solution with the volume fraction of 95% into the crude extract obtained in the step (1), adding dilute hydrochloric acid while stirring, adjusting the pH to 2.0-5.0, stirring for 15-30min, adding tetraethoxysilane, heating to 70-80 ℃ after precipitation, continuing stirring for 6-8h, filtering, precipitating until the water content is neutral, and drying to obtain a solid, namely the Chinese herbal medicine active ingredient nano material. |
