Pharmacognostical Studies of Bryophyllum pinnatum (Lam.) Kurz.
Context: Bryophyllum pinnatum (Lam.) Kurz. widely used in traditional as well as folk medicinal systems is locally known as Panphuti. Traditionally it is used for the treatment of kidney stones, urinary tract infection, burns and diarrhoea. Aims: In the present study, pharmacognostic studies of root, stem and leaf of Bryophyllum pinnatum (Lam.) Kurz. is carried out in order to standardize the plant for its phytochemical, phyiso-chemical and pharmacognostical. Methods and Material: For standardization of plant material morphological and anatomical characterization was carried out. Physico-chemical parameters viz. ash content, extractive values, heavy metal content was carried out as per Ayurvedic Pharmacopoeia of India. Phytochemical investigations were made to know the presence of various bioactive molecules, amino acid composition. Results: Intrastelar and extrastelar secondary growth with wood and periderm formation along with deposition of starch grains were observed in pith region of root and cortical region of stem. Calcium oxalate crystals were also present in the cortical region of the stem. Leaf lamina showed spongy parenchyma in mesophyll region and anisocytic type of stomata. Anthocyanin pigment was present below epidermal cells in petiole. Physico- chemical results can be serves as quality control data. Quantitatively carbohydrate, protein, flavonoids, phenolic compounds, saponins and pro-antocyanidins were found to be present in root, stem and leaf part of Bryophyllum pinnatum (Lam.) Kurz. Conclusion: The results of the study could be useful in setting some diagnostic indices for the identification and preparation of a monograph of the plant.
Key words: Bryophyllum pinnatum (Lam.) Kurz., Pharmacognosy, Phytochemical, Physico-chemical.
