Abstract

The objective of this research was to determine the characteristic of gardenia leaves herbal tea based on different of leaf positions and drying times. The research was conducted at the Laboratory of Agricultural Chemistry, Agricultural Faculty, Sriwijaya University, Indralaya from January to September 2015. The research used a Factorial Randomized Block Design with two factors and each treatment had three replications. The first factor was leaves position (positions 1 and 2, positions 3 and 4, and positions 5 and 6) and the second factor was the drying times (3, 4, and 5 hours). The measured parameters were yield, color (lightness, redness, yellowness), water content, ash content, IC50, total phenol, sensory characteristics of dried herbal tea (aroma and color) and sensory characteristics of brewed herbal tea (aroma, color and flavor). The results showed that leave positions had significant effect on yield, water content, total phenol, and IC50. Drying time had significant effect on yield, water content, and ash content. Furthermore, interaction of the two factors showed significant effect water content. The results showed that sensory analysis of different leave positions and drying times had significant effect on the dried herbal tea (color) and brewed herbal tea (aroma, color, and flavor). In conclusion, the A2B1 treatment (leave positions 3 and 4, drying time 3 hours) was found to be the best treatment with characteristics as follows water content of 4.89 %, ash content of 5.32 %, yield of 38.51 %, total phenol of 78.44 mg/L, IC50 of 0,048 μg/mL, dried herbal teas (aroma of 2.88 and color of 2.88) and brewed herbal tea (aroma of 2.60, color of 2.64 and flavor of 2.60).
