Dihydromyricetin is a natural active flavonoid compound. With its excellent biological activity, it is widely used in health products, food additives, pharmaceutical raw materials and other fields. Its core advantage lies in natural plant extraction, mainly derived from two medicinal and edible plants - Ampelopsis grossedentata and Hovenia dulcis. Dihydromyricetin from different plant sources can be made into various content specifications according to needs to adapt to different application scenarios, which are detailed below.

I. Core Plant Source is Ampelopsis grossedentata

Ampelopsis grossedentata is a woody vine of the genus Ampelopsis in the family Vitaceae, mostly growing in pollution-free natural ecological environments, and is the most important natural source of dihydromyricetin. The stems and leaves of Ampelopsis grossedentata are rich in dihydromyricetin and contain a variety of synergistic nutrients, laying the foundation for its excellent efficacy. We select high-quality Ampelopsis grossedentata raw materials and adopt modern green extraction technology (such as deep eutectic solvent extraction combined with macroporous resin separation technology) to maximize the retention of the natural activity of dihydromyricetin, with higher extraction yield and more controllable purity. The products produced cover three core content specifications, adapting to different high-end and conventional needs.

Specifications and Corresponding Uses of Dihydromyricetin from Ampelopsis grossedentata

98% High Purity Specification: Appearance is pale yellow or off-white fine powder, with extremely low impurity content. The content of heavy metals (lead, arsenic, mercury, etc.) is ≤ 1.0ppm, and all microbial indicators meet the standards. The core uses are pharmaceutical R&D raw materials and core components of high-end health products. It can be used in high-end health products for protecting the liver and relieving hangover, accelerating the decomposition of acetaldehyde (the metabolite of ethanol), and reducing liver cell damage; it can also be used as a high-purity antioxidant raw material in anti-aging cosmetics to scavenge free radicals and delay skin aging.

50% General Specification: Appearance is pale yellow powder with excellent cost performance. While retaining core activity, it is compatible with a small amount of plant-derived synergistic components. The core uses are food antioxidant additives and common health product ingredients. It can be added to oil-based foods and baked goods to inhibit oxidative deterioration and extend shelf life;

30% Water-Soluble Specification: After special processing, it is a flowable powder with significantly improved water solubility. It can be directly dissolved in aqueous systems without additional cosolvents, and has higher bioavailability. The core use is an exclusive raw material for aqueous system products, suitable for functional beverages, liver-protecting oral liquids, toners, essences and other water-based skin care products, as well as functional mouthwashes. It can be quickly absorbed by the human body or skin to exert corresponding effects.

 II. Another important plant source is Hovenia dulcis

Hovenia dulcis, commonly known as "guai zao", is a plant of the genus Hovenia in the family Rhamnaceae, and is also an important natural source of dihydromyricetin. In traditional applications, Hovenia dulcis has been commonly used to relieve discomfort, and the dihydromyricetin extracted from it has the same biological activity as that from Ampelopsis grossedentata. We select high-quality Hovenia dulcis raw materials and adopt targeted extraction technology to make two content specifications of 10% and 20%, which balance efficacy and cost, adapt to basic application scenarios, and form a complement to products from Ampelopsis grossedentata, ensuring the stability of raw material supply and application diversity.

Specifications and Corresponding Uses of Dihydromyricetin from Hovenia dulcis

- 10% Basic Specification: Appearance is light brown powder, rich in Hovenia dulcis-derived plant synergistic components, with significant cost advantages. The core uses are common food additives and feed additives. It can be added to functional teas and solid beverages to endow products with natural and healthy properties; it can also be used in feed formulas to help improve the antioxidant capacity of farmed animals.

- 20% Advanced Specification: Appearance is yellowish-brown powder with moderate purity and stable activity. The core uses are basic health product ingredients and daily chemical product raw materials. It can be made into simple packaged health granules to exert basic liver protection and heat-clearing and fire-reducing effects; it can also be used in daily chemical products such as hand sanitizers and body washes. Taking advantage of its antibacterial properties (inhibitory effect on Staphylococcus aureus, Escherichia coli, etc.), it helps improve cleaning effects.

III. Core Product Advantages and Quality Assurance

Natural and Safe: Select two medicinal and edible raw materials of Ampelopsis grossedentata and Hovenia dulcis, far away from industrial pollution. The green extraction process has no harmful residues, meeting multiple international certification standards such as ISO, HALAL, and HACCP.

Diversified Specifications: Covering a total of five specifications: 98%, 50%, 30% (water-soluble) from Ampelopsis grossedentata and 10%, 20% from Hovenia dulcis, fully covering from high-end R&D to basic applications, adapting to the needs of multiple industries.

Controllable Quality: All specifications are strictly tested by HPLC (High Performance Liquid Chromatography), with precise and controllable purity and strong batch stability. A complete Certificate of Analysis (COA) is provided, and the quality is traceable.

IV. Storage and Packaging

Storage Conditions: Seal and store in a cool and dry place, avoid direct strong light and high-temperature and humid environment, shelf life is 2 years.

The natural plant source of dihydromyricetin determines its safety and core efficacy. The multi-specification products from the two sources of Ampelopsis grossedentata and Hovenia dulcis provide efficient and adaptable natural active raw material solutions for various industries. According to your specific application scenarios, we can provide targeted source and specification recommendations and technical support.
