Phytochemical screening of extracts from Zingiber officinale (Ginger) and Curcuma longa (turmeric) Overview. Phytochemical screening is identification of different classes of phytoconstituents present in various parts of a plant. Phytochemicals are the chemicals that are present naturally in plants.

Qualitative phytochemical screening plays a crucial role in identifying various biochemical compounds produced by plants. The quantification of those metabolites may assist in the extraction, purification, and identification of the bioactive compounds for human use [ 83 ].

The phytochemical screening reveals the presence of phenolic compounds. • Acetone and diethyl ether extracts demonstrate strong antibacterial activity against both gram-positive and gram-negative bacteria. • The acetone extract exhibits antifungal activity against Fusarium culmorum. •

In this study, we evaluated the phytochemical constituents of extracts of stem wood of P. marsupium, and we determined the antioxidant, antimicrobial, anti-inflammatory, antidiabetic, and analgesic activities of these extracts. In addition, we also studied the toxicity of the extracts.

Phytochemical Screening. The confirmatory qualitative phytochemical screening of plant extracts was performed to identify the main classes of compounds (tannins, saponins, flavonoids, alkaloids, phenols, glycosides, steroids, and terpenoids) present in the extracts following standard protocols. 26–28. Test for Tannins

Phytochemical screening refers to the process of analyzing and identifying the chemical compounds present in plants, particularly the secondary metabolites, using a basic and cost-effective assay. AI generated definition based on: Himalayan Phytochemicals , 2018

Currently, phytochemicals are determined by various modern techniques, but the conventional qualitative tests are still popular for the preliminary phytochemical screening of plants. Phytochemicals (Greek: phyton = plant) are chemical compounds naturally present in the plants attributing to positive or negative health effects [1].
