STANDARDISASI PARAMETER NON SPESIFIK DAN SPESIFIK EKSTRAK ETANOL DAUN JAMBLANG (Syzygium cumini (L.) Skeels)

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.
