Compounds
Arum palaestinum serves as a significant subject for phytochemical investigation due to its diverse chemical composition. Detailed studies of this plant have successfully led to the isolation of specific flavone C-glucosides. Specifically, the plant contains the compound isoorientin, which is identified as luteolin 6-C-glucoside. Additionally, researchers have confirmed that Arum palaestinum contains vitexin, known as apigenin 8-C glucoside. These findings highlight the complex biochemical profile present within the species.
Conditions
Arum palaestinum demonstrates significant medicinal potential, including efficacy against SARS-CoV-2 in studies regarding COVID-19. This plant also possesses anti-tumorigenic properties that suggest a role in treating various types of cancer. Its leaves are utilized as traditional anti-diabetic agents due to their antioxidant activity, which aids in the management of diabetes. Furthermore, the lipophilic fractions of the plant show a strong inhibitory effect against porcine pancreatic $\alpha$-amylase. Finally, the isolated compound isoorientin from the plant has been shown to inhibit the contractions of the uterine smooth muscle of guinea pigs.
Preparations
Arum palaestinum is prepared as lipophilic fractions to evaluate its potential hypoglycemic effects. These specific fractions are sequentially separated from the plant leaves using a nonpolar solvent such as hexane. In the study's testing, this lipophilic preparation demonstrated a significant inhibitory effect on the porcine pancreatic α-amylase enzyme. The effectiveness of the Arum palaestinum lipophilic fraction was recorded with an IC50 value of 25.3 µg/mL. This result indicates that the prepared lipophilic components of the plant possess notable anti-diabetic properties.
Parts used
Arum palaestinum possesses leaves that serve as a significant component in the study of Jordanian medicinal plants. In recent research evaluating antioxidant capacities, the leaves of this species were specifically analyzed for their chemical properties. This particular plant part was categorized among those exhibiting moderate antioxidant activity based on DPPH-TEAC measurements. Such findings highlight the importance of utilizing various plant organs, including leaves, to understand their traditional medicinal roles.
