“…General experimental procedure FT-IR spectra (Fouirer Transform Infrared spectroscopy) were determined on Tracer-100 spectrophotometer (Shimadzu) and the spectra showed in cm -1 . 1 H NMR, 13 C NMR (Nuclear Magnetic Resonance) and 2D NMR (HSQC, HMBC and COSY) were recorded on BRUKER 600 Hz using Tetramethylsilane (TMS). Chemical shifts of carbon and proton NMR were given in δ (ppm).…”

Syzygium genus in Myrtaceae family is a rich source of phytochemical constituents that possess various bioactivities. One of well-known species of this genus, Syzygium aqueum, has been already utilized as traditional medicine. This plant is cultivated in countries of tropical regions of the world such as Malaysia and Indonesia. The aim of this study was intended to isolate phytochemical constituents from the stem bark of S. aqueum. To date, there have been no reports of chemical substances isolated from the stem bark of this plant. The powder of the stem bark was extracted followed by partitioned in order to obtain n-hexane extract which then was separated using silica gel column chromatographic several times until the pure compounds were resulted. The isolated compounds were identified by spectroscopie method including Fouirer Transform Infrared (FTIR) and nuclear magnetic resonance (NMR) and were known as 2,4-Di-tert-butylphenol & butyrospermol 3-β-O-palmitate, respectively. The spectoscopie data of those compounds were compared with references.

This comprises medicinal plants not only important for the treatment of diseases but also as potential material for maintaining good health and conditions. Better cultural acceptability, better compatibility and adaptability with the human body, and lesser side effects of plants made many countries in the world to depend on herbal medicine for their primary health care (Bari et al., 2021;CHOWDHURY et al., 2021;Hoque et al., 2021). For centuries, plants are being widely used for their natural resources isolated from various parts of a plant and have been used in the treatment of human diseases. Moreover, some of these plants produce edible fruits, while others simply produce dazzling flowers, which are so attractive and important economically as well.The knowledge of traditional medicine supports all other systems of medicine such as Ayurveda, Siddha, Unani, and even modern

AIM : The aim of this study was to determine the antibacterial compound of Altingia excelsa leaves to inhibit the growth of Entrococcus faecalis. METHODS : The study was true experimental laboratory design. Separating the ethyl acetate extract via their compounds using various chromatographic techniques. Four extracts from A. excelsa leaves was obtained by the maceration method. The highest inhibitory effect was then continued to be isolated until one compound was obtained. Therefore, additional assay to determine chemical structure of compounds was done using UV spectra, infrared (IR), core magnetic resonance (NMR), and comparison with spectra data from the literature. The data were analyzed by ANACOVA assay. RESULTS : The highest inhibitory effect was the ethyl acetate extract. The chemical structure of compound 1 was identified as an acidic compound 3,4,5 -trihydroxy benzoate, namely as the gallic acid which had inhibitory effect against Enterococcus faecalis. Antibacterial test against Enterococcus faecalis was done to determine inhibitory effect by its compound and MIC values showed of 12.25 µg/mL. CONCLUSION : Gallic acid as the compound of Altingia excelsa leaves had a strong inhibitory effect to Enterococcus faecalis.
