Chemical composition and bioactive compounds from leaves and mucilage of moroheiya (Corchorus Olitorius L.) (Thai)

Abstract

The study aimed to determine chemical compositions and bioactive compounds as well as mucilage
content from leaves of moroheiya or jute mallow (Corchorus olitorius L.). The results indicated that the levels
of ash, crude fiber, fat, protein and carbohydrate were 7.08, 3.54, 1.53, 3.23, and 3.56 % wet weight,
respectively. The concentrations of bioactive compounds and vitamins including b-carotene, a-tocopherol,
ascorbic acid, and total phenolic compounds were 35.374, 71.311, 130.533, and 550.20 mg/100g
whereas the concentrations of thiamin, niacin, pyridoxine, riboflavin, and folic acid were 0.018, 0.081,
0.066, 0.013, and 0.66 mg/100 g dried weight, respectively. The amount of mucilage from leaves of
moroheiya extracted using 2-propanol was 13.95%. The chemical compositions of mucilage including carbo-
hydrate, protein, fat, fiber, and ash were 58.89, 28.92, 1.11, 0.46, and 10.62% dry weight respectively.
The major sugars, xylose, glucose, and arabinose contained in the mucilage were 8.43, 8.39, and 6.34 %,
respectively.
