Abstract:

Abelmoschus manihot is cultivated in Guangdong, and the contents of amino acids, mineral elements, flavonoids, total phenols and polysaccharides were tested using the flowers and tender pods, and the antioxidant capacity was also evaluated. Sixteen amino acids (including 7 essential amino acids) were detected in the flowers and tender pods, and the total amino acids were accounted for 13.01% and 12.56% of the dry weight respectively. The ratio coefficient of amino acids (SRC) was 70.49 and 67.83, respectively. The contents of total flavonoids, total phenols, iron and potassium in flowers were significantly higher than those in tender pods, while the contents of polysaccharides, calcium and magnesium in tender pods were significantly higher than those in flowers. The scavenging experiments of DPPH and ABTS free radicals showed that the antioxidant ability of flowers was better than that of tender pods. Generally, the flowers and tender pods of A. manihot have edible and medicinal value, and are suitable for cultivating in Guangdong.

Key words: Abelmoschus manihot, amino acids, nutrients, mineral elements, antioxidant activity
