Products Description
Glycyrrhizin Flavonoids 30% is the core active flavonoid raw material precisely extracted and enriched from the natural roots and stems of licorice. The areas where licorice is grown have large diurnal temperature differences, abundant sunlight, and pollution-free soil, resulting in sufficient accumulation of effective components and high flavonoid content in the licorice. After cleaning, dust removal, and drying of the licorice roots and stems, the low-temperature water circulation extraction technology is used to precisely extract the flavonoid active substances in the raw materials. Then, through multi-stage membrane separation technology, polysaccharides, coarse fibers, and impurities such as ash are filtered out to complete the purification of the components. The appearance of the finished Licorice Flavonoids 30% is a uniform and fine brownish-yellow powder state, with a clean and transparent appearance.When swallowed, it has a slight licorice aftertaste. The water solubility of licorice flavonoids is very good, and they can quickly dissolve in warm water and normal temperature water. After dissolution, the solution is clear and transparent. It also has certain alcohol solubility, suitable for most water-based and weak alcohol-based formulation systems, with stable dissolution performance.

Function
Glycyrrhizin Flavonoids 30% can block the pathways of melanin transportation and deposition, inhibit tyrosinase activity, and reduce melanin production at its source. Unlike quick-acting whitening ingredients, it focuses on gentle brightening, gradually fading dullness, yellowish tones, and superficial pigmentation, evenly distributing the overall skin tone, and improving uneven skin tones caused by lack of sleep and ultraviolet radiation.
Glycyrrhizin Flavonoids 30% can effectively inhibit the activation of inflammatory factors within the skin, quickly alleviating problems such as redness, dryness, sensitivity and discomfort on the skin. They have a very good repairing effect on skin damage caused by seasonal sensitivity, hormone-induced redness, and external stimuli. It can also strengthen the skin barrier structure, reduce the loss of moisture and nutrients, lower the sensitivity of the skin to external stimuli, and fundamentally improve the fragile skin condition.
Glycyrrhizin Flavonoids 30% are classic liver-protecting active ingredients. They can reduce the metabolic burden on the liver, alleviate chemical and alcoholic liver damage, inhibit inflammatory responses in liver cells, promote the metabolism and self-repair of liver toxins, and effectively improve the fatigue state of the liver.
Glycyrrhizin Flavonoids 30% have excellent free radical scavenging ability, which can effectively neutralize the excessive reactive oxygen in the human body and the skin, reducing oxidative damage. Internally, it can slow down the aging of internal organs' functions, and externally, it can inhibit the darkening and fine lines of the skin caused by oxidation, improve the roughness and sagging of the skin, and solve aging problems such as roughness and relaxation, maintaining the skin in a delicate and transparent state.
Glycyrrhizin Flavonoids 30% can moderately regulate the human immune function, improve the chronic low-level inflammatory state of the body, and balance the metabolic cycle of the body. They also have the effects of relieving cough and soothing the throat, and alleviating respiratory tract discomfort, which can help the body maintain a healthy and stable state.
Application
In the skincare industry, Glycyrrhizin flavonoids is widely added to products such as serums, creams, toners, masks, body lotions and repair creams.
In the field of functional foods, Glycyrrhizin flavonoids can be used to produce products such as liver-protecting tablets, liver-nourishing capsules, antioxidant dietary powder, throat-soothing lozenges, and health-preserving tea beverages.
In the field of medicine, Glycyrrhizin flavonoids can be used as a pharmaceutical intermediate and excipient, and is applied in various preparations for regulating chronic inflammation and assisting in liver protection.
In the field of oral care, Glycyrrhizin flavonoids can be applied to oral care products such as toothpaste and mouthwash, and can alleviate oral mucosal inflammation and soothe gum sensitivity issues.

Our company

Shaanxi Lvke Chunyuan Biotechnology Co., Ltd. relies on the abundant medicinal plant resources of the Qinling Mountain region and its pristine natural ecological environment. The company specializes in the research, development, production, and sales of plant extracts, health food ingredients, chemicals, cosmetic raw materials, food additives, and peptides, as well as the self-operated import and export of related products. We provide innovative products and services to customers in the pharmaceutical, nutraceutical, and other related industries.
Our extraction workflow balances natural raw material characteristics with modern manufacturing controls. Rather than over-processing, we use gentle separation technology to isolate target active constituents while minimizing damage to the natural matrix.
Starting from raw material incoming inspection, each lot is screened for contaminants before entering production. After extraction, liquid undergoes continuous filtration and chromatographic purification to enrich target ingredients. The concentrated liquid is then converted into uniform powder via controlled drying.
Before release, every finished batch goes through comprehensive laboratory testing: HPLC assay for active content, heavy metal analysis, microbial examination and residual solvent testing.
We supply raw materials for functional health food and skincare brands across global markets. Our team provides technical support for formulation development and helps clients meet regional compliance requirements.
