| dc.description.abstract | ABSTRACT
Phytochemical analysis, toxicity test, the antioxidant activity and secondary metabolites of
bee pollen a hive products Trigona spp. has been investigated. Bee pollen samples
extracted with ethanol by masseration method with using a rotary evaporator. Ethanol
obtained crude extract was fractionated by ethanol and ethyl acetate. Secondary
metabolites of bee pollen with phytochemical analysis showed that the ethanol extract
contains alkaloids and phenolic rough. The ethanol extract fraction containing alkaloids.
Ethyl acetate extract fractions contain alkaloids and phenolic. In a test toxicity of an
increase in mortality of larvae shrimp (Artemia salina L.) and then processed using SAS
Probit Analysis to determine the lethal concentration 50% (Lc50). The results were
obtained data shows that the most active fractions is extract ethanol with value is 249.6079
ppm. Test results of antioxidant activity by DPPH method using spectrophotometry
showed that 50% inhibitory concentration (Ic50) is obtained in the crude extract was
104.84 ppm Ethanol, ethanol fraction value is 172.67 ppm, 75.99 ppm of ethyl acetate
fraction and vitamin C is 10.79 ppm, this suggests that the most active fraction is ethyl
acetate with Ic50 is 75.99 ppm. | en_US |
