 Licorice Root Extraction

Chinese herbal medicine is rich in bioactive components, and the extraction of these compounds is essential for their therapeutic efficacy. CO2 supercritical extraction has gained attention for its effectiveness in this field.

1. Active Components in Traditional Herbs

Many Chinese herbs contain flavonoids, alkaloids, and terpenoids, which contribute to their medicinal properties. Traditional extraction methods often result in low yields and compromised quality.

2. Case Study: Licorice Root Extraction

A study involving licorice root showed that CO2 supercritical extraction achieved an extraction efficiency of 90% for glycyrrhizin at 30 MPa and 55°C. This was significantly higher than the 60% achieved with conventional methods.

3. Data Support

The study revealed that 100 grams of licorice root processed using CO2 extraction yielded 10 grams of glycyrrhizin, whereas traditional methods produced only 4 grams. This illustrates the superiority of CO2 extraction.

4. Implications for Future Research

The application of CO2 supercritical extraction in Chinese herbal medicine holds great promise for enhancing the quality and efficiency of herbal extracts, aligning with the growing trend toward natural health products.
