A Comprehensive Pharmacognostical Evaluation and Phytochemical Profile of Upodika (Basella rubra Linn.)

Abstract

Background: Basella rubra L. (Basellaceae), commonly known as Indian or Malabar spinach belongs to family Basellaceae, is an herbaceous annual or biennial climbing herb found in tropical and sub-tropical areas. Upodika (Basella rubra Linn.) is known for its health-promoting properties, including antioxidant, antimicrobial, antiproliferative, and anti-inflammatory activities. Objective: The present study carried out phytochemical screening and pharmacognostic studies on different parts of Upodika (Basella rubra Linn.) to establish diagnostic features and identify bioactive compounds. Methodology: Pharmacognostical investigation of the leaf and stem involved macroscopic and microscopic examinations, including transverse sections and powder microscopy. Physicochemical parameters measured were total ash, acid-insoluble ash, water and alcohol-soluble extractives, and moisture content. Phytochemical screening of aqueous extracts used qualitative chemical tests to identify secondary metabolites. Results:  Microscopic examination of the leaf and stem reveals a distinct epidermis without trichomes and midrib contains collenchyma, parenchyma with 50–60 µm crystals, and central vascular bundles. Powder microscopy of the leaf identified polygonal epidermal cells, isocytic stomata, vascular tissues with pitted, scalariform, parenchyma, mucilage cells, and scattered prismatic and rosette calcium oxalate crystals are also present. Physicochemical evaluation confirmed all parameters met QSIMP prescribed limits, indicating good quality and purity. Phytochemical screening of the aqueous extract detected carbohydrates, proteins, amino acids, glycosides, saponins, phenolic compounds, and tannins, with the absence of alkaloids. Conclusion: Upodika (Basella rubra Linn.) shows distinct microscopic features and meets physicochemical quality standards. Phytochemical screening confirms the presence of key bioactive compounds, supporting its medicinal potential and aiding in standardization.
