Abstract

The leaves of Altingia excelsa were found to strongly inhibit SP-C1 human tongue cancer cell lines. This study was focused on identifying the antiproliferative compound found in A. excelsa leaves and assessing its mechanism of action. The active compound was isolated using column chromatography and identified by the spectroscopic method and was also tested for its anti-proliferative properties and the cell cycle analysis in SP-C1 cells by flowcytometry analysis. This work resulted in the isolation of a flavonoid, which was identified to be kaempferol and quercetin. The compounds inhibited SP-C1 cell proliferation in a time- and dose-dependent manner with IC50 values of 0.72 µg/mL and 0. 70 µg/mL for the 24 hours treatments, respectively. Furthermore, the flowcytometry analysis suggested that the compounds exerted its anticancer activities by inhibiting cell cycle. These results suggested that compounds found in A. excelsa providies a basis for its potential use in cancer disease management.

Abstract

Violet Batissa (Batissa violacea) is an important economic organism on the west-south coast of Aceh, because it is relatively high consumed by the community. However, gold mining activities carried out around the watershed are estimated to pollute the river and cause B. violacea to also be affected. The purpose of this study was to determine the level of mercury (Hg) and Lead (Pb) contamination in clam meat in Teunom, Aceh Jaya Regency. The research was conducted from June to September 2021. Sampling of clam was done by purposive sampling method. Hg and Pb were analyzed in clam meat using the Atomic Absorption Spectrophotometer (AAS) method. The results of the analysis showed that the Hg content in clam meat was between 0.12-0.63 mg/kg (mean 0.350.26 mg/kg), water 0.0026-0.0103 mg/kg (mean 0.00520.004 mg/kg), and sediment 1.3224-3.8767 mg/kg (mean 2.23241.427 mg/kg). Furthermore, the results of the analysis showed that the Pb content in clam meat, water and sediment had the same value at 3 stations with values 0.00020 mg/kg, 0.00030 mg/kg, and 0.00020 mg/kg, respectively. The conclusion of this study is that the Hg content in water and sediment has exceeded the threshold, while the clam meat is still in good quality standards. The Pb content in clam meat, water and sediment were also in good quality standards. Based on our study, B. violacea is still safe for consumption, while the water has been polluted and is recommended not to be utilized for human consumption.Keywords:Heavy metalRiverWaterSedimentBatissa violacea
