●What is purple cabbage anthocyanin ?
Purple cabbage (Brassica oleracea var. capitata f. rubra), also known as purple cabbage, is known as the "king of anthocyanins" because of its deep purple leaves. Studies have shown that every 100 grams of purple cabbage contains 90.5~322 mg of anthocyanins, far more than blueberries (about 163 mg/100 grams), and the content of the outer leaves is significantly higher than that of the inner leaves. Its core active ingredient is mainly cyanidin-3-O-glucoside (Cy-3-glu), accounting for more than 60%, supplemented by 5 types of compounds such as peony pigment derivatives, among which the structure of sinapinic acid peony pigment is unique to purple cabbage.
Green extraction process: Supercritical CO₂ extraction technology (purity above 98%) replaces traditional solvent method to avoid organic residues;
UV-C physical activation: Research by the Chinese Academy of Agricultural Sciences found that short-wave ultraviolet treatment can induce the expression of purple cabbage anthocyanin synthesis genes (MYB114, PAP1), increasing the content by more than 20% and extending the shelf life;
Microbial fermentation method: Using engineered strains to convert glycosides into active aglycones, the bioavailability is increased by 50%
●What are the benefits of the purple cabbage anthocyanin?
1. Breakthrough In Anti-Cancer Mechanism:
Triple negative breast cancer (TNBC):
Cy-3-glu specifically binds to TNBC cell membrane receptor ERα36, inhibits EGFR/AKT signaling pathway, and promotes cancer cell apoptosis. Clinical trials have shown that 75% of 32 TNBC patients have high expression of ERα36, and the tumor inhibition rate of mice fed with purple cabbage extract exceeds 50%.
Melanoma:
By blocking RAD51-mediated DNA repair, cancer cells are arrested in the G2/M phase and apoptosis is induced.
2. Cardiovascular And Metabolic Protection
Antioxidant core: The efficiency of purple cabbage anthocyanins in scavenging free radicals is 4 times that of vitamin E and 2.8 times that of vitamin C, significantly reducing the level of inflammatory factor TNF-α;
Vascular protection: Daily intake of 100 grams of purple cabbage anthocyanin can reduce bad cholesterol (LDL) levels and reduce the formation of atherosclerotic plaques59;
Blood sugar regulation: Flavonoids (such as quercetin) inhibit intestinal glucose absorption channels and improve insulin sensitivity.
3. Intestinal Health And Systemic Anti-Inflammation
The dietary fiber content is 2.6 times that of cabbage. After fermentation, it produces butyrate (a source of energy for colon cells), which increases the diversity of intestinal flora by 28% and reduces the risk of recurrence of ulcerative colitis;
Glucosinolates are converted into isothiocyanates, activating liver detoxification enzymes and removing carcinogens (such as tobacco metabolites).
●What Are The Applications Of purple cabbage anthocyanin ?
1. Medicine And Precision Medicine
Ant-cancer drug development: Cy-3-glu nano-targeted preparations have entered preclinical research for the treatment of ERα36/EGFR co-positive TNBC;
Diagnostic reagents: Based on the anthocyanin-Al³⁺ colorimetric reaction, low-cost heavy metal detection test strips are developed1.
2. Functional Foods And Health Products
Eye protection formula: Anthocyanins promote rhodopsin synthesis, improve visual fatigue, and are used in eye protection soft candies (daily dose 50mg);
Metabolic management: lipid-lowering capsules compounded with red yeast rice assist in regulating cholesterol.
3. Agriculture And Food Technology
UV-C preservation technology: Fresh-cut purple cabbage is treated with short-wave ultraviolet rays, extending the shelf life by 30% and increasing the purple cabbage anthocyanin content by 20%;
Loss reduction cooking solution: Steaming + lemon juice (pH control) retains 90% anthocyanins, solving the problem of "cooked food turning blue".
4. Beauty And Personal Care
Anti-aging skin care products: Add 0.5%-2% anthocyanin extract to inhibit collagenase activity, and clinically measured wrinkle depth is reduced by 40%;
Sunscreen enhancer: Compound zinc oxide increases SPF value and repairs Langerhans cells damaged by ultraviolet rays.
