Production Process of Woodruff Extract

The production process of Woodruff extract typically involves the following main steps:

  1. Raw Material Preparation: Fresh, clean Woodruff plants are selected as raw materials. Ensuring quality and purity is crucial for the final product's quality.
  2. Grinding and Crushing: The harvested Woodruff plants are ground and crushed to enhance extraction efficiency. This is usually done by adding the plants to a grinder or pulverizer until they reach a powdered or finely crushed state.
  3. Extraction Process: Appropriate extraction methods are selected, commonly including water extraction, ethanol extraction, and supercritical fluid extraction. During this process, the crushed Woodruff is mixed with an extracting solvent (such as water or ethanol) and subjected to heating and stirring to promote the dissolution and extraction of active components.
  4. Concentration and Separation: After extraction, the solution needs to be concentrated and separated to eliminate moisture and impurities, yielding pure Woodruff extract. This is typically performed through evaporation, concentration, or freeze-drying methods.
  5. Filtration and Purification: The concentrated extract is filtered and purified to remove any remaining solid particles and impurities, ensuring the purity and quality of the extract.
  6. Quality Testing: The extract undergoes quality testing, including active ingredient content and checks for harmful substances like microorganisms and heavy metals to ensure compliance with relevant standards and regulations.
  7. Packaging and Storage: Finally, the extract is packaged and sealed to protect it from oxygen, light, and moisture that could affect its quality. It should be stored in a cool, dry environment, avoiding high temperatures and direct sunlight to extend its shelf life and stability.

Following these processes, high-quality, pure Woodruff extract can be produced to meet the diverse needs of various industries.

Introduction to the Plant Source of Woodruff Extract: Distribution and Growth Environment

Woodruff (scientific name: Houttuynia cordata Thunb.) is a perennial herb belonging to the family Saururaceae, characterized as an evergreen or semi-evergreen herb. Its extract is widely utilized in medicinal, food, and cosmetic applications. Here’s an overview of the plant source of Woodruff extract, its distribution, and growth environment:

  1. Plant Description:
    Woodruff is a terrestrial plant, generally growing 10-30 cm tall, with heart-shaped leaves that have irregular serrated edges and long petioles. The flowering period is typically from spring to summer, with flowers usually white or light yellow, having heart-shaped petals and a subtle fragrance.
  2. Distribution:
    Originally found in southern China, Woodruff is primarily distributed in regions along the Yangtze River, Pearl River, and southern China, including provinces such as Guangdong, Guangxi, Fujian, Hunan, and Jiangxi. It is also present in Japan, Vietnam, and Korea.
  3. Growth Environment:
    Woodruff thrives in moist environments, commonly found in valleys, stream banks, wetlands, and damp forest areas. It is not picky about soil requirements, able to grow in acidic, neutral, and alkaline soils. The ideal temperature range for Woodruff growth is generally between 15 to 25 degrees Celsius.
  4. Growth Habits:
    Woodruff is a resilient plant with strong vitality, growing rapidly and capable of quick reproduction, often forming dense vegetation in suitable environments. Because of its preference for moist conditions, it proliferates in wet areas and may even become dominant in certain wetlands and marshes.

In summary, Woodruff is a common herb with a wide growth environment and distribution, thriving in moist conditions, making it relatively easy to locate and collect raw materials for Woodruff extract.

Processing and Storage of Woodruff Extract

The processing of Woodruff extract typically involves the following steps: First, fresh Woodruff plants are collected and undergo initial cleaning and treatment to remove impurities. Next, the cleaned Woodruff is crushed or chopped to enhance extraction efficiency. Then, effective extraction methods, such as water or ethanol extraction, are used to extract active components from the Woodruff. After filtering, concentrating, and drying, the final Woodruff extract is obtained. To ensure its quality and stability, Woodruff extract should be stored in a cool, dry, ventilated environment, avoiding direct sunlight and moisture while protecting against oxygen, light, and microbial contamination, thus prolonging its shelf life and maintaining the stability of its active ingredients.
