Immunomodulatory activity and phytochemical analysis of Hibiscus sabdariffa L. flower fractions

Hibiscus sabdariffa L. - a phytochemical and pharmacological review.

Hibiscus sabdariffa L. (Hs, roselle; Malvaceae) has been used traditionally as a food, in herbal drinks, in hot and cold beverages, as a flavouring agent in the food industry and as a herbal medicine. In vitro and in vivo studies as well as some clinical trials provide some evidence mostly for phytochemically poorly characterised Hs extracts. Extracts showed antibacterial, anti-oxidant, nephro-...

Toxicity and immunomodulatory activity of fractions of Hibiscus sabdariffa Linn (family Malvaceae) in animal models.

This study evaluated immunomodulatory properties and the sub-acute toxicity profile of two fractions of the aqueous alcoholic extract of the dried calyx of Hibiscus sabdariffa in experimental animals. Immunomodulatory activity was evaluated using red blood cell-induced immunostimulation. The fractions were not found to be toxic after 7-day administration, though there was severe weight loss wit...

In Nigeria the plant is used to make a popular beverage known as Zobo drink. Investigations revealed that the plant is highly rich in vital minerals and nutrients such as Iron, copper, calcium, magnesium, manganese required for healthy growth in humans. The phy...

Dietary fiber content and associated antioxidant compounds in Roselle flower (Hibiscus sabdariffa L.) beverage.

The beverage of Hibiscus sabdariffa flowers is widely consumed in Mexico. Polyphenols contained in plant foods are frequently associated with dietary fiber. The aim of this work is to quantify the dietary fiber, associated polyphenols, and antioxidant capacity of the Roselle flower and the beverage traditionally prepared from it and its contribution to the Mexican diet. Roselle flower contained...
