Abstract : The paper focused on the composition of the phytochemistry, the nutrient, and the mineral, and antioxidant activities of Morinda L. grown in three provinces (the central and the south area) in Vietnam. Phytochemistry (flavonoid, triterpenoid, alkaloid, and tannins), nutrient (protein, fat, carbohydrate, and fiber), minerals (Ca2+, Mg2+, Fe3+, Zn2+, Na+, Cu2+), and antioxidant activities (total, reducing power, and DPPH free radical scavenging) of species Morinda L. grown in Binh Phuoc, Khanh Hoa, and Ca Mau province in Vietnam were evaluated and compared. The results showed that the difference in the nutrient, the minerals, and antioxidant activities between species Morinda L. grown in three provinces occurred (p<0.05). The different species and habitats caused different nutrient, minerals, and antioxidant activities. Different phytochemistry appeared in all Noni samples. Antioxidant activities of species Morinda tomentosa grown in Khanh Hoa province was higher than Morinda citrifolia in Binh Phuoc and Ca Mau province. Minerals content decreased in order Binh Phuoc, Khanh Hoa, and Ca Mau. Nutrient content basing on protein content, Morinda L. grown Ca Mau province was evaluated higher than Binh Phuoc and Khanh Hoa.
