description | The study evaluated the chemical and antioxidant properties of Alternanthera brasiliana
leaves and Hibiscus sabdariffa calyces used in iron and zinc fortification of maizebambara
groundnut malt and maize-cowpea malt complementary foods. A. brasiliana
leaves and H. sabdariffa calyces were freshly harvested, dried at 50oC for 48 hours and
analyzed for the relevant chemical components and antioxidant activities. The vitamin A
content was 6996 and 745.6 μgRE/kg while the vitamin C was 238.26 and 294.78 mg/kg
respectively. The aqueous extracts of A. brasiliana and H. sabdariffa calyces contained
509.5 mg/kg and 5234.72 mg/kg of alkaloids, 1545 mg/kg and 384 mg/kg of anthocyanins,
767.3 and 235.83 mg/kg of carotenoids, 14,702.8 and 26,428.3 mg/kg of phenols, 1043.5
and 897.63 mg/kg steroids and 462.0 mg/kg and 1006.5 mg/kg of flavonoids respectively.
A. brasiliana and H. sabdariffa extracts had concentration-dependent DPPH activity with
IC50 of 1.76 mg/ml and 5.745 mg/ml, nitric oxide scavenging activity with IC50 of 0.675
mg/ml and 3.976 mg/ml while the ferric reducing power had an absorbance range of 0.5 –
0.982 and 0.959 – 0.986 respectively. The study revealed that A.brasiliana leaves and H.
sabdariffa calyces contain components that will impact positively on the health of the
infants when used to formulate complementary foods. |
