Item Investigation of different enzyme activities from Pergularia tomentosa L. and Ecballium elaterium L.(2016-01-01) Imen L.; Yotova L.Plant enzymes are derived from a variety of plants and are effective within a broad pH range. They have a greater activity and a higher stability than those of similar animal or microbial based enzymes. They are breaking down more proteins, fats, and carbohydrates in the broadest range of conditions than other sources. Many enzymes like proteinases, beta-amylase, lipoxygenase, L-asparaginase, polyphenol oxidase, tyrosinase, lipase are synthesized in plants. The present study is undertaken to assess the presence of the enzymes pointed above and their quantities in aqueous/ethanol extracts and in latex of two plants applied in medicine. The results obtained reveal presence of ß-amylase, proteolytic, pepsinogene, lipoxygenase, L-asparaginase, polyphenol oxidase, tyrosinase and lipase in aqueous extracts. The latex shows no presence of lipoxygenase but a good milk clotting activity is observed in case of Pergularia tomentosa L. However, Ecballium elaterium L. shows the same activities at a low concentration but no milk clotting activity.
