Content of total phenolic compounds and antioxidant capacity (FRAP) were investigated in the leaves of three sea buckthorn (Hippophaë rhamnoides L.) cultivars: ‘Otradnaja’, ‘Gibrid Pertjika’ and ‘Ljubitelskaja’, at different dates. In addition, major phenolic compounds (catechin, kaempferol, quercetin, epigallocatechin, kaempferol-3-O-glucoside, quercetin-3-O-galactoside, isorhamnetin-3-O-glucoside, rutin, gallic acid, procyanidin monomer glycoside, procyanidin dimer aglycone and hydrolyzable tannins I–III) were determined in ‘Ljubitelskaja’. Antioxidant capacity and the content of total phenolic compounds fluctuated during April, May and June, and then increased until the end of July, when the highest values were observed. Total phenolic compounds were strongly correlated with FRAP. Levels were generally higher in ‘Ljubitelskaja’ than in ‘Otradnaja’ and ‘Gibrid Pertjika’. In ‘Ljubitelskaja’, hydrolyzable tannins I–III occurred in higher amounts than did any of the other studied phenolic compounds. The developmental stage of the leaves (harvesting date) had a strong influence on content of phenolic compounds and should be carefully considered when harvesting sea buckthorn leaves for different purposes.

Ozonation Process

The aim of this research was to show the effect of the ozonation process on the quality of sea buckthorn (Hippophae rhamnoides L.). The quality of the ozonated berries of sea buckthorn was assessed. Prior to and after the ozone treatment, a number of parameters, including the mechanical properties, moisture content, microbial load, content of bioactive compounds, and composition of volatile compounds, were determined. The influence of the ozonation process on the composition of volatile compounds and mechanical properties was demonstrated. The ozonation had negligible impact on the weight and moisture of the samples immediately following the treatment. Significant differences in water content were recorded after 7 days of storage. It was shown that the highest dose of ozone (concentration and process time) amounting to 100 ppm for 30 min significantly reduced the water loss. The microbiological analyses showed the effect of ozone on the total count of aerobic bacteria, yeast, and mold. The applied process conditions resulted in the reduction of the number of aerobic bacteria colonies by 3 log cfu g−1 compared to the control (non-ozonated) sample, whereas the number of yeast and mold colonies decreased by 1 log cfu g−1 after the application of 100 ppm ozone gas for 30 min. As a consequence, ozone treatment enhanced the plant quality and extended plant’s storage life.
