Abstract
Tridex procumbens L. (Asteraceae) is a procumbent herb found throughout India. This plant is commonly known as ‘coat button’ in English and ‘Jayantiveda’ in Sanskrit. This plant is often treated as weed, and its pharmaceutical potential has been neglected. So, in the present investigation, exomorphic, anatomical, pharmacognostic, physico-chemical and chromatographic (fingerprinting) standards had been evolved for T. procumbens L. for quality control. This plant has useful pharmaceutical properties viz. anti-diabetic, antioxidant, anti-inflammatory, wound healing, analgesic, hepato-protective, anticance, and immune-modulatory. T. procumbens L. has ethnomedicinal importance. It is widely used in the formulations that cure wounds. T. procumbens is a rich source of phytochemicals such as alkaloids, flavonoids, saponins, carotenoids, B-sitosterols, fumaric acid, luteolin, and tannins. Anatomical parameters and quantitative microscopy provide a valuable key for the identification of this plant. The leaves of this plant have a thick cover of both glandular and eglandular trichomes. The presence of anomocytic stomata on both the surfaces of the leaf is a characteristic feature of T. procumbens leaf. The physico-chemical parameters viz. total ash, water soluble ash, and acid insoluble ash values were recorded as 12.60, 10.24, and 2.30% w/w respectively for leaf powder. The extractive values of leaf powder with ethanol, chloroform, acetone, water, and methanol yielded 8.80%, 4.10%, 7.20%, 8.60%, and 9.5% w/w respectively. The fluorescence studies of leaf showed a distinctive pattern. The characteristic TLC pattern of leaf extracts with Chloroform: Methanol (93:7) solvent system serves as the fingerprint for T. procumbens L.
