Full textRheum ribes L. (rhubarb) is one of the most important Mediterranean medicinal plants. Preparing its rhizomes’ aqueous decoctions has become common among patients suffering from various diseases. Instant Controlled Pressure Drop (DIC) is a High-Temperature Short-Time treatment (HTST) followed by an abrupt pressure drop towards the vacuum (approximately 5 kPa). This technology increases the expansion and reduces the tortuosity of the treated matrix to ensure better diffusivity of the extraction solvents and greater availability of the active molecules. On the one hand, our research aimed at the impact of DIC treatment on the rhizomes of a Lebanese species of R. ribes L. The evaluations were based on the contents of total phenolics (TPC) and flavonoids (TFC) as well as the antioxidant capacities of aqueous extracts of the treated rhizomes. The results showed a negative correlation between the saturated steam pressure applied and the values of TPC, TFC, and the antioxidant activities of the samples. However, DIC treatment time had no significant influence on the response variables. In addition to these two DIC operating factors (pressure and treatment time), the effect of the rhizomes water content (W) was also studied. The results showed that the increase of “W” does not lead to better yields of phenolic compounds. On the other hand, this study presents the impact of DIC treatment on the biological activities (antibacterial and antiproliferative effects) of rhizome extracts. The results revealed that the aqueous extracts of DIC-treated rhizomes show weak antibacterial powers on E. coli and S. aureus, with slightly superior results in inhibiting the growth of S. aureus. Regarding the viability test of melanoma cancer cells, the results showed that the DIC treatment positively impacts the antiproliferative power of the treated samples compared with the untreated point (aqueous MP). In particular, two samples among those tested recorded an antiproliferative power of 60%. The HPLC and UHPLC assays revealed the presence of three anthraquinones (emodin, chrysophanol, and physcion) in the rhizome extracts and about twenty compounds from the flavonoid family. However, the amounts of anthraquinones detected are not significantly higher in the extracts treated with DIC than in the untreated ones. Finally, it was found that the total phenolic content of an aqueous sample treated with the optimal DIC parameters is equal to that of an untreated hydroalcoholic sample. Further experiments will be necessary to validate this result
