The amount of antioxidants was obtained by grinding 3 rosella petals have dried, approximately 1.5 grams. Having given 200 ml water, then inserted into the spectrophotometer. Tools that analyze the chemical content based on the entire length of the refracted wave solution.
In the presence of antioxidants, free radical cells that damage the cell nucleus can be removed. That's why rosella have anticancer effects. Ingredients that were most responsible is the plant pigment anthocyanin or a responsible avoids cell damage caused by excessive exposure to ultraviolet light.
In New Zealand, John McIntosh, a researcher from the Institute of Food Nutrition and Human Health, Massey University, rosella extract with drying petals at a temperature of 50 degrees Celsius for 36 hours. Three grams of dried rosella diluted in 300 ml of water. The solution was put into a tube spectrophotometer. The result rosela contain 51 percent anthocyanins, antioxidant 24 percent.
Findings that are then used Yun-Ching Chang of the Institute of Biochemistry and Biotechnology, Chung Shan Medical University, Taiwan. Researchers then tested the effectiveness of the anthocyanins rosela to inhibit blood cancer or leukemia cells. Natural pigments oseile rouge - as rosella in France - not only inhibits the growth of cancer cells, but also turn it off. The dosage was only 0-4 mg / ml rosella. Affecting anthocyanin delphinidin 3-named sambubioside.
Some new research and preclinical research in the laboratory. There has been no direct proof of their effect on humans.

Efficacy zuring petals, rosella designation in Dutch, for hypertension also demonstrated Abd al-Aziz Sharaf of Sudan Research Unit, Institute of African and Asian Studies. As quoted Planta Medical Journal, rosella petals are hypotensive (antihypertensive) and anticonvulsants. Antihypertensive properties was tested clinically by M. Haji Faraji and A.H. Haji Shaheed Beheshti Tarkhani from the University of Medical Sciences and Health Services, Tehran, Iran. As much as
54 patients of high blood pressure on Tehran's Shariati Hospital and sistoliknya diastolic pressure was calculated 15 days before and after testing.
Patients were given a cup of tea steeping 3 rosella flowers. After 12 days, the patient's systolic average fell 11.2 percent, down 10.7 percent diastolic pressure. When consumption rosela discontinued 3 days, increased 7.9 percent systolic pressure, diastolic 5.6 percent. That proves efficacious rosela indeed lowers high blood pressure.
Rosella flowers grow from seeds / seedlings reach a height of one meter over and issued a flower almost all year round.
