Objective: This study aimed to comprehensively evaluate the chemico-pharmacological properties of methanolic extractives derived from Cyanometra ramiflora leaves, encompassing a spectrum of activities including cytotoxic, thrombolytic, membrane-stabilizing, antioxidant, antidiarrheal, hypoglycemic, and analgesic effects. Methods: Phytomolecules were identified using Gas Chromatography-Mass Spectrometry (GC-MS), while antioxidant activity was assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and total phenolic content tests. Cytotoxicity was determined through the brine shrimp bioassay, while thrombolytic activity was evaluated via clot lysis assays, and membrane-stabilizing effects were investigated for potential anti-inflammatory properties. In-vivo experiments using mice were conducted solely with the methanolic extract to assess central and peripheral analgesic, hypoglycemic, and antidiarrheal properties. Results: The presence of 47 compounds in the methanolic extract, with tetratriacontyl pentafluoropropionate (9.25%), pentatriacontane (8.75%), and 2-methylhexacosane (5.9%) being predominant. The dichloromethane-soluble fraction exhibited the highest cytotoxicity, with a 50% lethal concentration (LC50) of 11.05 µg/mL. Both petroleum-ether and methanol-soluble fractions demonstrated more than 50% lysis in thrombolytic activity assays. Under hypotonic and heat-induced conditions, the ethyl acetate and dichloromethane-soluble fractions of C. ramiflora significantly reduced erythrocyte hemolysis. Notably, the methanol-soluble fraction exhibited significant antioxidant potential with 50% inhibitory concentration (IC50) of 17.71 μg/mL compared to the standard EDTA (IC50 = 75.94 μg/mL). The hypoglycemic investigation revealed a 63.73% reduction at 90 min with a 600 mg/kg dose, while mild antidiarrheal activity was observed with a 37.5% reduction in diarrhea at 4 h intervals. Significant analgesic effects were demonstrated in both central and peripheral tests, with a 68.53% reduction in writhing during the peripheral test and an average tail immersion time of 5.38 s at 90 min. Conclusion: C. ramiflora leaves show promise as natural sources for various pharmacological activities, including cytotoxicity, thrombosis, inflammation, antioxidant, hypoglycemic, and analgesic effects. However, further comprehensive research is recommended to elucidate the precise mechanisms of action and analyze the phytochemical composition of C. ramiflora plants.

Introduction:Colocasia affinis Schott (Family: Araceae), found in the Asian region, is a traditional root vegetable consumed by the locals and well-known as Dwarf Elephant Ear.Methods: For the pharmacological exploration of this root vegetable, four kupchan fractions (i.e. HSF, DCMSF, EASF, and AQSF) from ethanolic extract of C. affinis were employed to in vitro i.e. antioxidant, cytotoxicity, and antimicrobial and in vivo i.e. antidiarrheal and analgesic assays, followed by phytochemical screening and GC-MS protocol.Result and Discussion: In the antioxidant assay, the AQSF showed promising potential with an IC50 value of 29.4 μg/mL and additionally, it exhibited the greatest overall phenolic content, measuring 57.23 mg GAE/gm. of extract among other fractions. The AQSF also revealed promising cytotoxic activity in brine shrimp lethality assay with an LC50 value of 1.36 μg/mL. Both AQSF and EASF exhibited substantial antimicrobial efficacy against both gram-positive and gram-negative bacteria as well as various fungus species with a remarkable zone of inhibitions compared to standards. Whereas, during both the castor oil-induced antidiarrheal and acetic acid-induced writhing assay, the DCMSF at 400 mg/kg dose exhibited the highest 51.16% reduction of diarrhea and 52.33% reduction of writhing. Phytochemical screening revealed several chemical groups while GC-MS study of different fractions of dwarf elephant ear ethanolic extract revealed 48 different bioactive phytochemicals in total. Several targets such as KAS, DHFR for anti-microbial activities, GLR, URO for antioxidant activities, EGFR, BCL-2 for cytotoxicity, KOR, DOR for antidiarrheal activities and COX-2, TNF-α for analgesic activities are considered for molecular docking against identified phytocompounds and standards along with ADME/T studies to ascertain their safety, efficacy and drug likeliness profiles.Conclusion: To recapitulate, our study revealed that vegetables such as dwarf elephant ear can be considered as a prospective source of therapeutics and drug development besides their nutritive food values.

Achillea cucullata is a perennial herbaceous plant that has a long history of medical use in many cultures. The present research focuses on the biological activity and therapeutic potential of A. cucullata, namely its antibacterial and anticancer properties. While previous studies have shed light on the cytotoxic and antibacterial capabilities of Achillea cucullata aerial parts, there is still a considerable gap in knowledge concerning the anticancer potential of leaf and flower extracts. A. cucullata’s leaves and flowers were extracted using methanol. The total phenolic and flavonoid contents were evaluated. The antioxidant, cytotoxic, and antibacterial properties were evaluated against both Gram-positive and Gram-negative bacteria. The Gas Chromatography–Mass Spectrometry (GC–MS) analysis of A. cucullata leaf and flower extracts showed numerous amounts of bioactive components, including carvacrol, a TBDMS derivative; 2-Myristynoyl-glycinamide, acetylaminobenzothiazol-2-yl)-2-(adamantan-1-yl); Isolongifolol; (3E,10Z)-Oxacyclotrideca-3,10-diene-2,7-dione; and 3-Heptanone, 5-hydroxy-1,7-diphenyl. The extract has a high level of phenols and flavonoids. Cytotoxicity studies found that A. cucullata leaves and flowers had dose-dependent toxicity against MCF-7 and HepG2 cancer cell lines, with flowers being more effective. Apoptotic genes (caspase-3, 8, 9, and Bax) were upregulated in treated MCF-7 and HepG2 cells, whereas anti-apoptotic genes (Bcl-xL and Bcl-2) were reduced. Antibacterial screening revealed significant activity against both Gram-positive and Gram-negative pathogens. Overall, the research highlights the varied therapeutic potentials of A. cucullata, adding to the knowledge of plant-derived extracts in lowering disease risks. Future research should concentrate on in vivo studies to assess the effectiveness and safety of these substances.
