Penelitian ini bertujuan untuk mengetahui perbandingan konsentrasi efektif serta pengaruh peningkatan konsentrasi cinnamaldehyde dengan senyawa turunan hidrazida sinamat hasil reaksi basa Schiff terhadap aktivitas antibakteri dan antioksidan. Aktivitas antibakteri diketahui dengan melihat pengaruh sampel terhadap daya hambat pertumbuhan bakteri Escherichia coli dan Staphylococcus aureus sedangkan aktitivitas antioksidan diuji menggunakan DPPH kemudian menghitung nilai IC50. Sintesis ester dari cinnamaldehyde dilakukan dengan bantuan DIB ((diacetoxyiodo)benzene) dan iodin. Hasil esterifikasi kemudian direaksikan dengan hidrazin hidrat untuk membentuk senyawa hidrazida sinamat. Kemudian dilakukan reaksi basa Schiff dengan 4-hidroksi benzaldehida. Sehingga terbentuk senyawa turunan hidrazida sinamat. Senyawa hasil ini dikarakterisasi dengan instrumentasi MS (Mass Spectrometry) dan spektrofotometer FTIR. Pengujian aktivitas antibakteri menggunakan metode difusi agar (difusi Kirby dan Bauer), menunjukkan bahwa konsentrasi efektif cinnamaldehyde untuk menghambat bakteri Staphylococcus aureus dan Escherichia coli adalah pada konsentrasi 5000 ppm dan 10000 ppm, sedangkan konsentrasi efektif senyawa turunan hidrazida sinamat untuk menghambat bakteri Staphylococcus aureus adalah pada konsentrasi 10000 ppm dan negatif untuk menghambat bakteri Escherichia coli. Cinnamaldehyde dan senyawa turunan hidrazida sinamat diuji aktivitas antioksidan menggunakan DPPH. Nilai IC50 dari senyawa turunan hidrazida sinamat (IC50 = 88,95 ppm) lebih rendah dibandingkan dengan IC50 dari cinnamaldehyde (IC50 = 1372,96 ppm).

NADES digunakan sebagai alternatif pelarut hijau alami yang memiliki potensi untuk menggantikan pelarut organik konvensional yang berbahaya bagi lingkungan karena NADES bersifat biodegradable. Kulit kayu manis (Cinnamomum burmannii Blume) adalah sumber tanaman yang mengandung trans-cinnamaldehyde dan coumarin yang memiliki efek farmakologis. Dalam penelitian ini, ekstraksi dilakukan dengan metode refluks menggunakan etanol 96% dan metode Ekstraksi Berbantuan Ultrasonik menggunakan Natural Deep Eutectic Solvents (NADES), untuk mendapatkan kadar trans-sinamaldehyde dan kumarin yang optimal dari kulit kayu manis. Optimasi dilakukan pada dua variabel, yaitu persen kenaikan air dalam NADES berbasis kolin klorida dan waktu ekstraksi. Penentuan kadar trans-cinamaldehyde dan kumarin dilakukan dengan menggunakan Kromatografi Cair Kinerja Tinggi (HPLC) dengan fase gerak 0,04% larutan asam asetat glasial-asetonitril (40:60 v/v) dan dideteksi pada panjang gelombang 280 nm. Kondisi optimal diperoleh pada saat ekstraksi 40 menit dengan penambahan air 50% persen ke NADES. Penambahan air dan waktu ekstraksi memiliki pengaruh terhadap hasil ekstraksi. Dalam ekstraksi metode UEA menggunakan tingkat NADES trans-cinamaldehyde dan kumarin masing-masing diperoleh pada 9,87 dan 11,09 mg/g simplisia. Sementara itu, ekstraksi metode refluks menggunakan pelarut etanol 96% diperoleh tingkat trans-sinamaldehida dan kumarin masing-masing adalah 1,47 dan 3,92 mg/g simplisia. Hasil ini menunjukkan bahwa NADES mampu menarik lebih banyak senyawa trans-cinamaldehyde dan kumarin dibandingkan dengan 96% etanol.

NADES is used as an alternative to natural green solvents which has the potential to replace conventional organic solvents which are harmful to the environment because NADES is biodegradable. Cinnamon bark (Cinnamomum burmannii Blume) is a source of plants containing trans-cinnamaldehyde and coumarin which has pharmacological effects. In this study, extraction was carried out by reflux method using 96% ethanol and Ultrasound-Assisted Extraction method using Natural Deep Eutectic Solvents (NADES), to obtain optimum levels of trans-sinamaldehyde and coumarin from cinnamon bark. Optimization is carried out on two variables, namely the percent increase of water in the choline chloride-based NADES and the extraction time. Determination of trans-cinamaldehyde and coumarin levels was carried out using High Performance Liquid Chromatography (HPLC) with a mobile phase of 0.04% solution of glacial-acetonitrile acetic acid (40:60 v/v) and detected at a wavelength of 280 nm. The optimum conditions were obtained at the time of extraction of 40 minutes with 50% percent water addition to NADES. The addition of water and extraction time has an influence on the extraction yield. In the extraction of the UAE method using NADES levels of trans-cinamaldehyde and coumarin were obtained at 9.87 and 11.09 mg/g simplicia, respectively. Meanwhile, the extraction of the reflux method using 96% ethanol solvent obtained levels of trans-sinamaldehyde and coumarin were 1.47 and 3.92 mg/g simplicia, respectively. These results indicate that NADES is able to attract more trans-cinamaldehyde and coumarin compounds compared to 96% ethanol.

Organic solvents have several effects such as toxicity to humans, difficult to decompose and can cause environmental pollution. Natural deep eutectic solvent (NADES), has been proposed as an alternative to green extraction. In this study, choline chloride-based NADES with 3 acid pairs (lactic acid, malic acid and citric acid) were evaluated for their ability as a solvent to extract trans-cinamaldehyde and coumarin from the bark of Cinnamomum burmannii. Optimization of extraction conditions is done by determining the percent of water addition and extraction time. Extraction was carried out using ultrasonic methods with NADES solvents and maceration methods using 96% ethanol solvents. Determination of trans-cinamaldehyde and coumarin levels was evaluated using High Performance Liquid Chromatography (HPLC). The results showed that choline chloride-lactic acid (1: 2) with the addition of 40% water and 30 minutes extraction time produced the highest levels of trans-sinamaldehyde which was 9.24 mg / g and the highest coumarin content was and 11.60 mg / g. Extraction results using NADES solvents produce higher levels of compounds compared to maceration methods using 96% ethanol solvent. Based on this research, it can be concluded that NADES choline chloride-lactic acid can attract trans-cinnamaldehyde and coumarin compounds from cinnamon bark.

The present study was conducted to evaluate the antibacterial activity of aqueous and ethanol extracts of Cinnamomum zeylanicum on different types of dental plaque microorganisms. Screening study was performed to detect the potential antibacterial activity agains S. aureus, E. coli, S. mutans, L. casei, B. fragilis, A. actinomycetemcomitans and dental plaque pool samples. From the screening test, values of Minimum Inhibitory Concentration (MIC) were determined. The lowest MIC value was 25 mg/ml of aqueous and 12.5 mg/ml of ethanol extract for S. aureus. The highest MIC values were seen in A. actinomycetemcomitans and dental plaque anaerobic pool samples with 300 mg/ml of aqueous extract and 150 mg/ml of ethanol extract. The MIC values for aqueous extracts ranged from 25 to 300 mg/ml whereas for ethanol extract it ranged from 12.5 to 150 mg/ml. The high concentration of ethanol extract, 100 mg/ml in the fixed plant concentration test, showed the strongest inhibition effect for all the organism tested. Generally, the ethanol extract of Cinnamomum zeylanicum demonstrated a stronger antibacterial activity compared to the aqueous extract. This study also compared the antibacterial activity of chlorhexidine with that of the plant extracts. Chlorhexidine showed a higher antibacterial effect on the microorganisms, with almost all organisms inhibited.
