PENETAPAN KADAR TOTAL ALKALOID DAN FLAVONOID PADA BINTANGUR (CALOPHYLLUM SOULLATTRI BURM.F.) MENGGUNAKAN FTIR DAN SPEKTROFOTOMETRI UV-VIS

Abstract

This research aims to determine the total levels of alkaloids and
flavonoids in Bintangur plants (Calophyllum soullattri burm.f.)
using the FTIR method and UV-Vis spectrophotometry. The
Bintangur plant is known to have various medicinal properties,
such as antioxidant and anti-inflammatory. The extraction
methods used include maceration, soxhletation, and reflux. The
samples used were Bintangur leaves and bark, which were
obtained from Tanjung Batu, Sorong City. The results showed that
alkaloid and flavonoid levels could be detected well, providing a
significant indication of the potential use of this plant in medicine.
FTIR analysis was used to identify functional groups, while UV-Vis
spectrophotometry was used to determine alkaloid and flavonoid
concentrations. It is hoped that this research can contribute to the
standardization of Bintangur extract in the pharmaceutical
industry, as well as increasing understanding of the benefits of
local medicinal plants in Indonesia. These findings are an
important step in the development of safe and effective herbal
products.
