Potential of Cinnamomum iners wood as antimicrobial agent

Abstract

The wood of Cinnamomum iners (Medang Teja) believe in giving multiple beneficial, especially in traditional usage. However, due to the lack of studies regarding this species made this species unable to express its full potential being commercialised by the industry. Thus, this study is prosecuted with the objectives to evaluate the chemical composition and analyse the biological activity of extractive and essential oil derived from Cinnamomum iners (Medang Teja) wood. The samples that evaluated comprises of 100%, 1%, 2%, 3% essential oils and extractive of chemical composition are conducted through Fourier Transform Infrared Spectroscopy (FTIR) and Gas-Chromatography Mass Spectrometry (GCMS) analysis. Meanwhile analysing of its biological activity is made through antifungal and antimicrobial activity. The results found that the functional group presents in all the samples shared one similar functional groups which are aliphatic hydrocarbons. For 100% essential oil, the functional groups are aliphatic propionate ester, aliphatic hydrocarbons and tertiary aliphatic alcohols. 1%, 2%, and 3% essential oil consist of the same functional groups which are olefins, aliphatic hydrocarbons and aliphatic acetate esters. Extractives have aliphatic hydrocarbons and primary aliphatic alcohols. Through GCMS, the major compounds found in the samples are 2(1H)-Naphthalenone, octahydro-, trans-Linalool,. beta. Fenchyl alcohol, Camphor, Benzene, ethyl-(CAS) EB. The similar compound found in all samples are Linalool, terpinene-4-ol, Terpineol, Copaene, Cadinene. From the antifungal analysis, it is proved that all of the samples can hold the antifungal traits, as all the samples show the effects of inhibitory on both brown-rot, Coniophora puteana and white-rot fungi, Pycnoporus sanguineus. The most susceptible organisms are the Coniophora puteana which showed a lower average diameter of inhibition zone for all the sample. Lastly, the samples shown a positive result in being antimicrobial agents for both gram negative, Escherichia coli and gram positive, Staphylococcus aureus.
