Wateris the biological milieu—the substance that makes life possible—and almost all the molecular components of living cells, whether they be found in animals, plants, or microorganisms, are soluble in water. Molecules such as proteins, nucleic acids, and carbohydrates have anaffinityfor water an...
as well as some of the new substances that are formed through oxidation of phenolic units, are toxic to different degrees. They can therefore serve as carbon sources only for special species of microorganisms. Besides the organic residue derived from higher animals and plants, many substances synth...
Results showed that 63 components were identified in essential oils. Phenylethyl alcohol (77.978%), α-terpineol (31.810%) and docosane (21.644%) were the most abundent constituents of flower oil, leaf oil and fruit oil, respectively. Based on bioactivity-guided fractionation, three active ...
