Abstract:

This study aimed to analyze the nutritional composition, active constituents and heavy metal contents of Moringa
oleifera leaves from different regions in Yunnan province. Samples were selected from six representative regions of Yunnan
province. The results showed that the leaves of Moringa oleifera from Dehong contained the highest protein content of
28.4%. Moringa oleifera leaves from six regions contained up to 9.27% essential amino acids and the total amount of amino
acids in the samples from Dehong was 20.54% which contained 150.00 mg of vitamin C/100 g. Among the six regions,
Moringa oleifera leaves from Pu’er contained the highest contents of soluble polysaccharide and crude fiber, which were
13.27% and 34.47%, respectively. Calcium content in Moringa oleifera leaves from Dali was 2.78%. In addition, Moringa
oleifera leaves also contained abundant lysine and other essential amino acids as well as polyphenols with less heavy metal
pollution and were green, non-pollution and highly safe to consume.

Key words: Moringa oleifera, different habitats, component, analysis and research
