Abstract

In recent years, the information about carcinogenic substances contained in Ocimum basilicum L., such as Safrole and Eugenol, has been rapidly spread through the Internet, causing panic among the general public and consequently reducing the industrial applicability of Ocimum basilicum L. To verify the truthfulness of that information, this study extracted substance from the stems and leaves of the commercially available Ocimum basilicum L. using sealed solvents. After that, the substance was analyzed to identify if there were any carcinogenic substances contained in Ocimum basilicum L., such as Safrole and Eugenol. The commercially available Ocimum basilicum L. was acquired, cut into pieces, sealed with 99.5% ethanol at 70℃, and extracted using ultrasonic atomizer. Then, two extracted supernatants were appraised using Gas Chromatograph / Mass Spectrometer (GC/ MS) to verify their ingredients. According to the results, 30 chemical constituents were found from the stems and leaves of Ocimum basilicum L. The main components of the top three are the p-allylanisole, the β-cadinene and the β-elemene, and there is no the carcinogenic ingredients of the safrole and the eugenol were found.
