It is a herbaceous plant that belongs to the Asteraceae family. People of South Africa have predominantly used it throughout history as a medicinal tea, for cleansing or purifying the blood, treating boils, headaches,

Fruits were analyzed for total soluble solids (TSS) or °Brix, titratable acidity (TA) and juice pH. Chemical properties evaluated were; total phenols, anthocyanin, antioxidant, organic sugars and acids. Results of the study revealed significant variations in all measured parameters attributed to location. Total soluble solids content varied from 16.0 – 17.3 (°Brix), pH values from 2.7 – 3.0, titratable acid content varied from 1.3 – 1.7 and maturity index from 9.7 – 13.4. Anthocyanins, total phenols and antioxidants were 772 – 1134 mg/100ml; 1611 – 1834 mg/100ml and 12.57 – 14.84 mg/100ml, respectively. Organic acids (citric and malic) and organic sugar (fructose, glucose and sucrose) had significant differences, while no differences were shown in Acetic acid across the production areas. Location and cultivar therefore pl...
