Quantification of Farnesol From Red and Green Leaves of Syzygium campanulatum

S. campanulatum, also known as “kelat paya” can grow young leaves with various colors. Due to this characteristic, S. campanulatum is commonly used in landscaping. S. campanulatum under family of Myrtaceae and genus of Syzygium which is rich in secondary metabolites among which is farnesol. Farnesol...
