| dc.description.abstract | Tahongai (Kleinhovia hospita Linn) is a medicinal plant that has various properties. This study aims
to determine standardization parameters the tahongai aqueous extract. The research method was carried
out by macroscopic and microscopic observations on Tahongai powder, then extracted by infusion method.
The aqueous extract was then subjected to organoleptic determination, identification of secondary
metabolites, determination of water soluble content and determination of water content, heavy metal
contamination determination, and microbial contamination test. The result for determination of
standardization parameter were: yield of the infusion was 10.38961%. Organoleptic test showed solid
form, medium characteristic odor, black color and bitter taste. Identification of secondary metabolites
showed a group of secondary metabolites of saponins and triterpenoids. Determination of the water soluble
extract content 11.648% and the water content 10.328%. Heavy metal contamination Hg, Cd, Cr, Ni, Pb
and As respectively were <0.0001; <0.0001; 0.9167; 49.2815; <0.0001 and 44.1774 mg/Kg. Then on
microbial contamination, the result was 8.8 x 103 colonies/g. Based on PERKABPOM No. 12 of 2014,
the water extract of tahongai meets the minimum quality requirements for heavy metal content and
microbial contamination. | en_US |
