Factors affecting bioactive substance content and antioxidant capacity of young rice leaves

Abstract

Rice is a crop that has numerous food utilities and different benefits in both cultivars and kinds of usability, such as whole kernels, germinated rice and young rice leaves. The purposes of this research were to study the rice morphology, factors (age of young rice leaves, cultivars, and planting conditions), affects biological properties and antioxidant capacities in four cultivars which are wheat, rice berry, Homdokphayom, and Jamookdam. The research results showed that after growing for a period between 8 to 11 days, the young Rice berry grass had the highest of total phenolic compound and antioxidant capacity, which were 540.01 mg/g fresh weight and 86.36%, respectively.  Although, planting materials which were rice husk ash, earthworm manure and earthworm manure mixed with chemical fertilizer have insignificant impacts on the total phenolic compound and antioxidant capacities. However, earthworm manure mixed with chemical fertilizer has nomentous effect on rice growing (p≤0.05).
