Our Co2 Supercritical Gromwell Root Extract
Lithospermum erythrorhizon root commonly known as Red Gromwell root is usually conical with twisted branches, 7-14cm long and 1-2cm in diameter. The appearance is purplish-red or purple-black, and the skin is rough and thin, easy to peel off. Gromwell root is easy to break, and the section is dark purple. Gromwell root co2 extract contains various active ingredients and has a wide range of applications in pharmaceuticals, dietary supplements, and cosmetics. We use advanced CO2 supercritical technology to obtain the extract powder. This Gromwell Root Powder contains approximately 30% total naphthoquinones, a group of compounds that cause the extract powder's dark red appearance. These natural ingredients include Shikonin, Acetylshikonin, Deoxyshikonin, Isovalerylshikonin, beta-dimethyl acryl shikonin, beta-hydroxyl-isovalerylshikonin, beta-acetoxy-isovaleryshikonin, and Isobutyrylshikonin. These naphthoquinones compounds are highly lipid-soluble.

Identification Method
Take 0.5g of the Gromwell Root Extract, add 5 ml of ethanol, soak for 1h and filter. Wash the residue with 2ml of ethanol, add the washing solution to the filtrate, and concentrate to 1mL as the test solution.
Take shikonin ethanol solution as the contrast solution, absorb the test solution, and contrast solution separately, spot on the same silica gel G-CMC thin-layer plate, develop with toluene: ethyl acetate: formic acid (5:1:0.1), take out, and dry in the air.
In the chromatogram of the test solution, there are the same purple-red spots at the position corresponding to the chromatogram of the contrast solution. According to the 1995 edition of the Pharmacopoeia of the People's Republic of China, the result is calculated as L-shikonin.
Pharmacological Properties
Shikonin and its naphthoquinone derivatives have been shown to be active ingredients with an array of wound-healing, antifungal, anti-HIV, antioxidant, and anti-fertility properties in Gromwell Root Powder. It has been employed for thousands of years in helping with rashes, measles, smallpox, eczema, carbuncles, and burns. One study showed that shikonin greatly inhibited the transcriptional activity of the GM-CSF promoter by blocking the binding of the TFIID protein complex to the TATA box. Furthermore, shikonin potently inhibits the promoter/transcriptional activity of the pro-inflammatory cytokine TNF-α. Shikonin can further exert dramatic and acute effects on human monocytes at the genomic and proteomic levels. Another study showed that shikonin substantially inhibited the early expression (within 0.5 hours) of about 50 genes, particularly the cytokines TNF-α, IL-1β, and IL-4, the chemokines CCL4 and CCL8, and the regulation of inflammation agents NFATC3 and PTGS2. Several studies by others have shown that shikonin has various pharmacological properties, such as antioxidant, antiplatelet, and antiatherosclerotic properties. Shikonin is also considered a latent drug for treating allergic diseases, inhibiting PMA + cAMP-induced IL-4 and IL-5 expression by downregulating the expression of GATA-3 and Maf.
