TINGKAT KEKUATAN ANTIOKSIDAN DAN KESUKAAN MASYARAKAT TERHADAP TEH DAUN GAHARU (AQUILARIA MALACCENSIS LAMK) BERDASARKAN POHON INDUKSI DAN NON-INDUKSI
ABSTRACT: During the long
enough harvesting cycle, aloes leaves can be used as medicine and poured drink
that has a role as antioxidants. This research was to study the societies
predilection level to aloes tea and the strength of aloes leaves antioxidant
activity based on the induction and non-induction tree. This research used
1,1-diphenyl-2-picrylhydrazil (DPPH) method with the observation parameter are
the percentage of free radicals submerged at the 60th minute with different
concentration (40 ppm, 60, ppm, 80 ppm and 100 ppm) and the value of IC50
(Inhibitory Concentration) was analyzed by regression similarity. The result of
antioxidant activity observation by using the UV-Visible light
Spectrophotometer at the swell length of 516 nm showed that the result of aloes
leaves simplicia ethanol extract (EESDG) induction and non-induction had IC50
value of 99.42 ppm and 70.40 ppm. The result of EESDG had a significantly
antioxidant activity. The hedonic test results showed that the stroge of aloes
leaves for 0 month were the most predilection in the society due to the taste
at induction treatment with the taste score 3.83 but due to the aroma and
colour, had the same value 3.10 and 3.83. Aloes leaves tea at the 2 month
storage which the most predilection in society was at the non-induction
treatment, by the score of taste, aroma and colour were 3.30, 2.80 and 3.80.
