In our work the effectiveness of supercritical carbon dioxide extraction was studied on volatile and nonvolatile components of Lamiaceae herbs. The aim of our investigations was to determine the optimal extraction parameters yielding high amount of volatiles and nonvolatiles in a desirable composition. As plant materials, dried and powdered cude drugs of Satureja hortensis, Ocimum basilicum and Melissa officinalis were chosen. Pressure (8-50 MPa), temperature (35-60 °C), time (5-60 min) and the ratio of modifier (5-50% methanol) of extraction were regulated. Results obtained by supercritical fluid extraction (SFE) were compared to that of the conventional extraction procedure, hydrodistillation (HD). In the case of Satureja hortensis, Ocimum basilicum and Melissa officinalis extract yield of SFE was comparable to the essential oil amount obtained by hydrodistillation from the same drug. Essential oil rich extracts were analysed by GC-FID, while extracts rich in nonvolatile compounds were analysed by HPLC. We have found that yield and quality of SFE extracts highly depend on the conditions of extraction.

A field trial was conducted to assess the effect of organic inputs and bioagents on growth, yield, and quality of okra. Thirteen treatments in the experiment were laid out in Randomized Block Design with three replications. The results revealed that the yield parameters were best in conjoint application of organic and inorganic fertilizer whereas the physical and quality parameters showed a maximum in integrated application of organic amendments and bioagents. On the basis of the findings it may be concluded that FYM @ 20 t/ha + VAM + Pseudomonas + Trichoderma + Azotobacter resulted the highest B: C ratio (2.66) and can be recommended as substitute for the inorganic combination of FYM @ 10 t/ha + 50:50:50 kg NPK/ha for higher quality yield with remunerative return.

Leafy shoots of sweet basil (Ocimum basilicum Linn.) were exposed to the vapor of either dilute acetic acid (AA) or of upland rice vinegar (URV) – both solutions were diluted to contain 4% of acetic acid – for 10 min and stored at 12°C. The sweet basil exposure to AA had a 16% increase in shelf life and those exposures to URV 35% increase compare to the control. There were no significant differences in fresh weight loss during storage between the AA and URV but both had significantly lower fresh weight losses than the control. The chlorophyll content of both AA and URV were significantly higher than the control. The radical scavenging was significantly higher in the URV than in the AA and the control. The electrolyte leakage was both significantly lower in the URV than in the AA and the control. The occurrence of lipid peroxidation was similar in both the AA and URV, and both were significantly lower than in the control. These results indicate URV has potential as an effective way of raising quality and extending postharvest storage of sweet basil shoots.
