Abstract

Plasma activated water (PAW) recently received much attention as an alternative food preservation method. However, its effects on food quality are still scarce. This study evaluates the effect of PAW processing time on bioactive compounds of rocket-salad leaves including: 18 phenolic compounds, vitamin C, riboflavin, nicotinic acid, and nicotinamide. Moreover, the impact of PAW on both antioxidant (DPPH) and peroxidase (POD) activities was also investigated. This was performed using HPLC-DAD, HPLC-MS/MS, and spectrophotometric analysis. All treatments induced non-significant increases in total phenolic contents. However, depending on processing time, significant increases or decreases of individual phenolic compounds were observed. PAW-10 and -20 increased the ascorbic acid content to 382.76 and 363.14 mg/100 g, respectively, compared to control (337.73 mg/100 g). Riboflavin and nicotinic acid contents were increased significantly in PAW-20 (0.53 and 1.26 mg/100), compared to control (0.32 and 0.61 mg/100 g, respectively). However, nicotinamide showed non-significant increase in all treatments. Antioxidant activity improved significantly only in PAW-20, while peroxidase activity was reduced up to 36% in the longest treatment. In conclusion, PAW treatment could be an effective technique for rocket decontamination since it positively influenced the quality of rocket, improving the retention of polyphenols and vitamins.

Abstract

Tanacetum sinaicum (Asteraceae) is a rare perennial herb growing wild in the mountains of Southern Sinai (Egypt). It is a medicinal and endangered plant. So, this work aimed to develop an in vitro propagation method for the conservation of this highly threatened plant. Sterile seedlings were used as a source of explants which were cultivated on Murashige and Skoog (M&S) media supplemented with different combinations of growth regulators for callus formation and induction of shoots and roots. M&S media with 1 mg/L kinetin (Kn) showed direct shoot induction. For root induction, excised shoots were transferred to M&S medium supplemented with 1 mg/L naphthalene acetic acid (NAA). Moreover, n-hexane extracts of wild and in vitro propagated plants were analyzed for their volatile constituents by gas chromatography-mass spectrometry (GC-MS) which resulted in the identification of 38 and 27 constituents, accounting for 87.75 and 75.51 % of their total composition; respectively.
