CHAPTER 4 RESULTS AND DISCUSSION 4.1 Percentage yield Fresh leaves of C. nardus with 1 kg portion yielded about 22.57g of aqueous crude extract‚ which was approximately about 2.26% of yield. The result showed that fresh leaves had a higher percentage yield compared to the air-dried leaves‚ it was only 1.3% yield which conducted by Koba et al. (2009) with the similar extraction technique.
