Evaluation of total antioxidant and phytochemical from different maturity of jackfruit leaves using ultrasonic-assisted extraction

Jackfruit or Artocarpus heterophyllus is a tropical fruit that having high medicinal value to human health. Through the previous results of pharmacological studies, it proves that jackfruit leaves provide benefits in medicine such as have some properties of antioxidants, antidiabetics, anticancer, a...
