Abstract

Introduction: Streptococcus mutans has been known to play a major role in dental caries development. This tooth decay is the most common oral disease affecting people in the world. Hence, discovering the new herbal antibacterial agent seems to become more promising yet challenging. One of natural antibacterial source is the peel of Citrus aurantifolia, as it may contain antibacterial active compounds against pathogenic oral microbes. This study was aimed to isolate antibacterial compound from essential oil of Citrus aurantifolia and to analyse its antibacterial activity against oral Streptococcus mutans ATCC 25175. Methods: Type of research was laboratory experimental. The essential oil was isolated from peel of Citrus aurantifolia by hydro-distillation technique and further isolation of antibacterial compounds was conducted by combination column chromatography using organic solvent, and the structure was determined by UV-Vis, infrared (IR), 1D NMR of 1H-, 13C-NMR and DEPT 135° in CDCl3 spectrometers methods. The antibacterial activity was tested against Streptococcus mutans ATCC 25175 using the Kirby-Bauer method. Results: 0.75% yield was obtained from the essential oil of peel Citrus aurantifolia and after purification, an antibacterial compound was identified as β-pinene with the molecular formula C10H16. Furthermore, the β-pinene from peel of Citrus aurantifolia exerted inhibition growth against Streptococcus mutans at concentration of 2000, 1000, and 500 ppm by showing respectively, inhibition values of 13.0, 11.9, and 11.6 mm on paper disk. Conclusion: In the present study, the essential oil of Citrus aurantifolia peel is proven to contain prospective antibacterial compound (β-pinene) that potentially can be used as natural antibacterial alternative choice to manage oral disease associated with Streptococcus mutans infection.

Abstract

Aglaia is the largest genus of the Meliaceae family which contains terpenoid compounds. This type of compounds showed a diverse structures and biological activities that can be found in natural resources. Aglaia elaeagnoidea is a species from Aglaia genus that only has a few previous research. This study was aimed to isolate and determine the chemical structure of terpenoid compounds from the ethyl acetate extract of A. elaeagnoidea stem bark. Ethyl acetate extracts were separated and purified by various chromatographic techniques to obtain compounds 1-5. Compounds 1-5 were identified their chemical structures by spectroscopic methods (IR, MS, and NMR) and comparison with previous reported spectral data. Compounds 1 and 2 were identified as eudesmane-type sesquiterpenoids, 5-epi-eudesm-4(15)-ene-1β,6β-diol (1) and 6α-Hydroxy-eudesm-4(15)-en-1-one (2). Compounds 3-5 were identified as dammarane-type triterpenoids, 20S,24S-epoxy-25-hydroxydammarane-3-one (3), 20S,24S-epoxydammarane-3α,25-diol (4), and 3α-epi-cabraleahydroxy lactone (5). These compounds are first time reported from this plant. Compounds 1-5 were tested for cytotoxicity against HeLa cervical cancer cell and DU145 prostate cancer cell and as a result, compound 4 (20S,24S-epoxydammarane-3α,25-diol) showed the stronger activity compared to other compounds.
