Abstract
ABSTRACT
The content of active compounds and the quality of extracts cannot be guaranteed to always be in a
constant amount, so it is necessary to standardize. This study aims to prove the ethanol extract of
jamblang leaves (Syzygium cumini (l.) Skeels) fulfill the standardization of non-specific and specific
parameters as a natural medicine. The ethanol extract of jamblang leaves was extracted by extracting
using ultrasonic methods The extract was tested for non-specific parameters including: determination
of water content, total ash content, acid insoluble ash content, drying losses and heavy metal
contamination. Whereas the specific parameter tests include: identity, organoleptic extract,
compounds dissolved in water and ethanol, and chemical content. Test results were analyzed
descriptively and compared to standard parameters. The results of non-specific parameters showed a
moisture content of 8.04 ± 2.83%, a total ash content of 3.81 ± 1.95%, an acid insoluble ash content of
0.54 ± 0.73%, a drying loss of 9.08 ± 3.01, metal contamination Pb <3.692 mg / kg, As <0.277 mg /
kg, Hg <0.018 mg / kg. While the results of specific parameters indicate the identity of the name jamblang (Syzygium cumini (l.) Skeels), organoleptic extracts thick, blackish brown color, bitter taste
and distinctive odor, with a content of water-soluble compounds 9.67% ± 3.05 and content the
compound dissolves in ethanol 14.33% ± 5.03 and contains flavonoid compounds, saponins and
phenols. Based on these results jamblang leaf extract meets the standard non-specific parameters and
specifics.
