Abstract

Basil leaf (O. basilicum L) could be developed as a herbal supplement  due to its phenolic compounds which have antioxidant activity. Extract of this plant would be more effective as a natural antioxidant if it is coated with nanochitosan. Nanochitosan was prepared from the parrot fish (scarus sp) scale and chitosan of crab’s shell by gelatin ionic method. The purpose of this study was to determine  the effects of the nanochitosan coating on phenolic content of basil leaves. The parameters tested were phenolic content of  the basil leaf extracts and nanochitosan coated basil leaf extracts. The results show that the  size’s average of nanochitosan  from fish scales were in 657,4 nm. Phenolic compound was not detected in both the fishscale and crab’s shell derived chitosan. In the other hand, phenolic compound of the basil leaf extract  showed the presence of phenol content of 34.38 mg/kg. In basil leaf extracts coated with nanochitosan from fish scales and nanochitosan of crab’s shell showed a phenolic content of 39.28 mg / kg and 57.44 mg/kg respectively. This suggests that synthesis of phenolic compound was induced when the extract of basil leaves was coated by nanochitosan.Keywords: basil leaves, chitosan, nanoparticles, phenolic compounds

Abstract

An increasing production of avocado in Indonesia  has resulted in abundant seeds as wastes. Avocado’s seeds contain potential antioxidant compound, such as phenolic compound, which could be exploited for human consumption. Utilization of seeds as functional food could be more efficient by coating with a certain substance. Chitosan is a bio-compatible and non-toxic compound, and could be used as coating agent in the form of nanochitosan. The purpose of this study was to evaluate the content of  phenolic-compound in extract of avocado’s seed with and without coated by nanochitosan. In this study, the extract of avocado’s seed was coated with  Parrot fish scale (Scarus sp) derived nanochitosan, compared with nanochitosan from crab’s shell. Nanochitosan was prepared from chitosan by gelation ionic method. The results show that avocado’s seed extract has 44.89 mg/Kg of phenolic content,  much lower than the content in the extract coated with nanochitosan of fish and crab shell, which were 84.08  and 113,67 mg/Kg, respectively.   Therefore, coating with nanochitosan was proven increasing the phenolic compound in the extract of avocado’s seed.  Keywords: avocado, nanochitosan, phenol
