Abstract. The aim of this study was to determine the nutritional content of Chenopodium album young
shoots and mature plant-leaves locally consumed in the Eastern Cape Province of South Africa. Young
shoots and mature plant-leaves of C. album were analysed for proximate, vitamins and mineral composition
according to AOAC standard analytical procedures. The mean values for carbohydrates, protein and fibre in
the young shoots were 4.0, 32.2 and 37.0 (g/100g) while those for the mature plants were 7.0, 29.2 and 36.5
(g/100g) respectively. The calcium, potassium and magnesium content of young shoots was 12991, 45799
and 7982 (mg/1000g) while those for the mature plants were 18213.2, 49028.6 and 13821.5 (mg/1000g)
respectively. Sodium was 48.8 and 68.0 (mg/100g) in young shoots and mature plants respectively. The
microelements of Fe, Zn, Cu in the young shoots were 218.1, 26.2 and 14.0 (mg/1000g) while for the mature
plant, they were 120.4, 23.0 and 9.1 (mg/1000g) respectively. Arsenic was 1.8mg/1000g, Sb and Sn
measured <0.05mg/1000g and Cr measured 0.9mg/L in both young shoots and mature plants. The
measurements for vitamin C were 5.6 and 5.2(mg/100g) while β-carotene measured 46 and 68 (μg/100g) in
young shoots and mature plants respectively. Generally, the nutrient content of young shoots and mature
plant-leaves were similar (P>0.05). These results indicate that C. album young shoots and mature plants
could serve as potential sources of important dietary nutrients for the alleviation of problems associated with
malnutrition in South Africa.

1. Introduction
The young shoots and leaves of Chenopodium album are consumed as vegetable in the rural areas of the
Eastern Cape Province and other parts of South Africa [1]. The plant is commonly found along roadside
paths, bushes and gardens where it grows as an erect annual herb producing angular stems, ribbed with
longitudinal dark green or red streaks [2]. It is usually harvested by villagers and local dwellers and prepared
with maize as porridge. It is referred to as lamb’s quarters in English and Imbikicane in isiXhosa. It belongs
to the family Chenopodiaceae [3].
Studies carried out in different parts of the world indicate that C. album is a rich source of nutrients,
antioxidants and important dietary elements [1] and [4]. However, many indigenous leafy vegetables
including C. album are neglected and despised in the urban areas of South Africa, despite their nutritional
richness and potential to contribute to healthier diets in the country. This is a methodological deficiency
given the high rate of vitamin A deficiency in South Africa, especially among children under 10 years of age
[5].
C. album is known to be resistant to pests, diseases and thrives well in minimally nutritive soils [6]. The
plant may therefore constitute a good source of genes for genetic improvement of other crop varieties.
