“…Mahlke, Zanetti, Machado, Manfron, and Athayde () investigated that the leaf of Buddleja thyrsoides and Mangifera indica had anomocytic type stomata and trichomes in abaxial face. Similarly, Gupta, Sharma, and Rao () and Okhale et al () worked on stem of Callicarpa macrophylla , Careya arborea ; Scoparia dulcis , and Stachytarphet jamaicensis ) reported similar findings. Pharmacognostic evaluation gives valuable information regarding the morphology, microscopical, and physical characteristics of the crude drugs (Rakholiya & Chanda, ).…”

The present study was conducted on characterization of morpho-anatomical, phytochemical, and bio-elemental analysis of root, stem, and leaf of Verbascum thapsus. Morphologically Verbascum is a biennial plant that flowers for a month and a half in mid-to late summer. Various organoleptic features of root, leaf, and stem were recorded. Anatomically the T. S of the root, stem, and leaf showed a typical dicot histological differentiation. Leaf possessed anomocytic stomata, crescent shape vascular bundles, and covered with long and stellate type trichomes while, stem contained collateral type of vascular bundles and a well-developed pith to store phytochemicals responsible for various pharmacological activities. The powder drug study through scanning electron microscopy revealed the presence of various types of tissues. Branched, tree like and stellate trichomes in root and leaf help in absorption and reduce loss of water. These anatomical features are responsible for the survival of the plant as biennial. Four macro elements (Na, K, Ca, and Mg) and seven microelements (Cr, Cu, Fe, Mn, Ni, Zn, and Cd) and their concentrations in ppm were also studied using Atomic Absorption Spectroscopy. Phytochemical screening of methanolic extract showed existence of various secondary metabolites, while mucilage and anthraquinones was not detected. The present study helps to understand the taxonomic identification of the plant based on morpho-anatomical features and throws the attention of the researchers to carry out the work for developing its various formulations, which can ultimately be beneficial for the human beings as well as animals.

“…The standardization is a very important step in establishing the correct identity, purity, safety and quality of crude drug and it should be established before the inclusion of crude drug in herbal pharmacopoeia (Gupta et al, 2012). Recently, there has been an emphasis in standardization of medicinal plants of therapeutic potential.…”

Background: Melaleuca alternifolia (Myrtaceae) is a well-known, commonly used, tall shrub plant in Ayurvedic medicine. Traditionally, it is used for its antimicrobial potential to treat cutaneous infections. No attempts have been made regarding pharmacognostic investigation of the plant till date. So, the present study was aimed to establish standards with the help of different pharmacognostic parameters. Methods: Various pharmacognostic parameters (morphological, microscopic, physicochemical evaluations and preliminary phytochemical screening) were studied along with fluorescent and thin layer chromatographic analysis of the extract. Result: Morphologically Melaleuca alternifolia is a shrub having height of 7 m with layered and papery bark. Leaves have an arranged pattern, petiole is 1 mm in length; linear-acute with dimensions of 10-35 mm x 1 mm. Organoleptic features shows that leaves have characteristic odour and astringent taste. The transverse section of the leaf reveals the existence of epidermal layers, mesophyll tissues, vascular bundles and secretory cavities. The stomata are anomocytic and leaf constants such as stomatal number is 180-200-225, stomatal index is 3.8-4.4-5.9, vein islet number is 18.68 (average), veinlet termination number 20.3 (average) and palisade ratio is 5.5-6.4-6.9. The results of phytochemical screening showed the occurrence of different phytoconstituents (flavonoids, phenolic tannins, phytosterol and terpenoids). Conclusion:The present study evaluated various pharmacognostic parameters which will help in quality control (standardization) of Melaleuca alternifolia leaves in crude form, in herbal formulation and also aid in the preparation of an herbal monograph for the species.

Piper species are reported to have great medicinal value in Indian medicine. Fruits of Piper nigrum Linn is commonly known as "Kalimiri" belongs to the family of Piperaceae and widely used as a pungent condiment. Traditionally it is used as antipyretic, diuretic, aphrodisiac, immune-stimulant, antioxidant, hepatoprotective, digestive, rubefacient, counter irritant, antiseptic, antispasmodic agent. Present work is related to standardization of Piper nigrum by using Pharmacognostic (Macroscopy, Cytomorphology, Physical constants) and Photochemical study of fruit. All parameters were studied according to the WHO and Pharmacopoeial guidelines to standardize the Piper nigrum.
