Description of the Source Plant for Ilex pubescens Extract: Distribution and Growth Environment

Ilex pubescens (common name: hairy winterberry) is a well-known shrub belonging to the Aquifoliaceae family. Here are detailed insights about the source plant for Ilex pubescens extract, including its description, distribution, and growth environment:

  1. Plant Characteristics:
    Ilex pubescens is an evergreen shrub, typically growing 1-3 meters tall, sometimes reaching up to 5 meters. Its leaves are oval or elongated, leathery, dark green on the upper side, and densely hairy on the underside, hence the name "hairy winterberry." Its flowers are small, white or pale yellow, blooming in spring. The fruit is a red berry containing 1-4 seeds each.
  2. Distribution Range:
    Ilex pubescens is mainly found in various provinces of China, including Jiangsu, Zhejiang, Anhui, Jiangxi, Fujian, Hunan, Guangdong, Guangxi, Sichuan, Guizhou, and Yunnan, as well as regions in Vietnam and Myanmar. It grows across a wide elevation range, found in the edges of forests, hillsides, and open areas from low to mid-elevation zones.
  3. Growth Environment:
    Ilex pubescens is highly adaptable, thriving in moist conditions. It typically grows in mountainous or forest margins, valleys, creek sides, roadsides, and open scrubland. It prefers acidic or neutral soils and is not very particular about soil quality, but it does not thrive in poorly drained soils. In southern China, it is commonly found in evergreen broadleaf forests.
  4. Reproductive Methods:
    Ilex pubescens reproduces mostly through seeds and cuttings. Seed reproduction is its primary method, as seeds have some resistance and can germinate and grow given suitable environmental conditions. Cutting propagation involves using plant tissues such as stems, branches, or leaves during the vigorous growth period for artificial reproduction.

As a common shrub in nature, Ilex pubescens holds significant ecological and economic value. Its hairy leaves, red berries, and unique growing environment make it an integral part of mountain and forest edge vegetation. The berries also have medicinal and edible value, widely utilized in traditional Chinese medicine and as food additives.

Processing and Storage of Ilex pubescens Extract

The processing of Ilex pubescens extract primarily involves the following steps: First, fresh leaves, branches, or fruits of Ilex pubescens are harvested, washed, and treated to remove impurities and unwanted parts. Next, extraction methods are employed, commonly including water extraction, ethanol extraction, or supercritical fluid extraction. After extraction, the liquid undergoes concentration, filtration, and purification to yield Ilex pubescens extract. Finally, depending on requirements, the extract may be dried or frozen for stability and quality preservation.

Regarding storage, Ilex pubescens extract should be kept in a cool, dry, well-ventilated environment, away from direct sunlight and heat. The extract should be placed in a sealed container to prevent contamination from air, moisture, or foreign materials. Regular checks on the extract's appearance and properties should be performed during storage to ensure no abnormalities occur. If any irregularities are detected, prompt action must be taken. Typically, properly stored Ilex pubescens extract can maintain stability and activity for an extended period.
