The Research Of Mainly Biological Activity Effects Of Hibiscus Extract
Roselle (Hibiscus Sabdariffal L.) is called the ruby in plantage, has high nutritional value which is one kind of ideal raw material for nature health care products. Hibiscus Extract is taken from the roselle calyx for the biological activity effects. The roselle calyx’s biological activity effects contain organic acids, anthocyanidins, polyphenols and polysaccharides, which is also the mainly effects in our Hibiscus extract. Our World-Way Hibiscus Extract mainly contains hydroxycitric acid, anthocyanidins, polyphenols. We can customize the detail specification as your requirements.
A. Organic Acids
In organic acids, there are citric acid (12%~20%), hydroxycitric acid, hibiscus acid (13%~24%), malic acid (2%~9%), tartaric acid (0.02%~8%), and some few oxalic acid and ascorbic acid (0.02%~0.05%).
In the dry calyx, the total anthocyanin content is 1.5%. In it, 85% is delphinidin-3-Sambubioside, which is the main source of the antioxidant power of hibiscus extract. In present research. The antioxidant activity of roselle is attributed to its strong clearing effect on active oxygen and free radicals. Therefore, hibiscus extract has a significant antioxidant effect. Also, there is cyanidin-3-sambubioside, delphinidin-3-glucoside and cyanidin-3- glycoside.
We find there is some flavonoids, such as quercetin, protocatechuic acid, gallic acid, Chlorogenic acid Chlorogenic acid isomers,5-hydroxymethylfurfural etc. Because roselle extract contains anthocyanins, protocatechuic acid, and isomers of hydroxycitric acid, it inhibits citrate lyase, thereby inhibiting the biosynthesis of triglyceride and cholesterol. Therefore, roselle extract has the effect of lowering blood lipids.
The monosaccharides in the calyx are mainly arabinose, galactose, glucose, and rhamnose, also contain a small amount of galacturonic acid, glucuronic acid, mannose and xylose. These biological activity effects make the hibiscus extract can not only be antioxidant and lower blood lipids, but also lower the blood pressure, antibacterial and diuretic, which is good for nature medicinal and edible dual-use raw material for food and cosmeceuticals industry.
