Phytochemistry, Ethnopharmacological Uses, Biological Activities, and Therapeutic Applications of Cassia obtusifolia L.: A Comprehensive Review

Cassia obtusifolia L., of the Leguminosae family, is used as a diuretic, laxative, tonic, purgative, and natural remedy for treating headache, dizziness, constipation, tophobia, and lacrimation and for improving eyesight. It is commonly used in tea in Korea. Various anthraquinone derivatives make up its main chemical constituents: emodin, chrysophanol, physcion, obtusifolin, obtusin, au rantio-obtusin, chryso-obtusin, alaternin, questin, aloe-emodin, gluco-aurantio-obtusin, gluco-obtusifolin, naphthopyrone glycosides, toralactone-9-β-gentiobioside, toralactone gentiobioside, and cassiaside. C. obtusifolia L. possesses a wide range of pharmacological properties (e.g., antidiabetic, antimicrobial, anti-inflammatory, hepatoprotective, and neuroprotective properties) and may be used to treat Alzheimer’s disease, Parkinson’s disease, and cancer. In addition, C. obtusifolia L. contributes to histamine release and antiplatelet aggregation. This review summarizes the botanical, phytochemical, and pharmacological features of C. obtusifolia and its therapeutic uses.

Anti-inflammatory and Matrix Metallopeptidase-1-Inhibitory Effects of the Cassia obtusifolia L. Seed Extract on Particulate Matter-induced Skin

Purpose: This study aimed to investigate the effects of the Cassia obtusifolia L. seed extract (CSE) on particulate matter (PM)-induced skin.Methods: The effects of CSE on cell viability were evaluated using a skin cell line. To determine the anti-inflammatory effects and matrix metallopeptidase-1 (MMP-1)-inhibitory effects of CSE on PM-induced skin, NO and MMP-1 expressions were measured using an enzyme-linked immunosorbent assay (ELISA) kit. Also, the effects of CSE was investigated the induction of IL-8 and TNF-α treated PM on reconstructed human full thickness skin models.Results: It was observed that CSE decreased NO production in PM-induced RAW 264.7 cells without cytotoxicity. In addition, CSE decreased the expression of MMP-1 in PM-induced cells in a dose-dependent manner. CSE decreased IL-8 and TNF-α production in a PM-reconstructed human skin model.Conclusion: These results indicate that CSE could be used as a cosmetic material to induce anti-inflammation and inhibition of MMP-1 in PM-induced skin.

IN VIVO AND IN VITRO INVESTIGATIONS OF PHARMACOLOGICAL POTENTIALS OF CASSIA OBTUSIFOLIA PLANT

Objectives: Cassia obtusifolia L. belonging to the Family Caesalpiniaceae, proposed to have abundant pharmacological potential and widely consumed as laxative, diuretic, and stomachic. The aim of the present research was to study the anti-inflammatory, analgesic, antipyretic, and antioxidant potentials of C. obtusifolia plant. Methods: Various acute and chronic animal models such as Carrageenan-induced paw edema, tail immersion method, acetic acid-induced writhing, and in vitro methods were used to study the profound pharmacological and antioxidant potentials. Results: The results for pharmacological study were statistically analyzed by one-way ANOVA followed by Dunnett’s multiple comparisons using INTA software. Conclusion: The present study reveals that C. obtusifolia possesses comparable anti-inflammatory, analgesic, antipyretic, and antioxidant potential.
