Sustainability, Vol. 11, Pages 6590: Effect of Fertilization in Selected Phytometric Features and Contents of Bioactive Compounds in Dry Matter of Two Varieties of Basil (Ocimum basilicum L.) (Sustainability)
 




This study investigated the effects of sustainable, organic and standard mineral fertilization in selected phytometric features and contents of bioactive compounds in dry matter of two varieties of Ocimum basilicum L. The herbal material was first examined for its phytometric characterisation and then subjected to the combined convective pre-drying and vacuum-microwave finish drying method (CPD-VMFD). The energy consumption for the drying process of plant material in the case of CPD-VMFD is lower in comparison to the convection method (CD). The obtained dry material was assessed for determination of the colour parameters. Next, the analysis to identify the total content of polyphenols and the antioxidant properties (ABTS) was done. The dried material was subjected to head space–solid phase microextraction (HS-SPME) to determine volatile compound content. The herbal material obtained from the basil cultivated with an addition of sustainable, organic fertilizer was found to have a significantly higher content of bioactive compounds than the control, especially of polyphenols and volatile compounds like eucalyptol. Presumably, this is an effect of the elicitation process resulting from the fact that extract from common nettle was applied as an organic fertilizer component.
