Background: Oxalis pes-caprae is also called as \“sourgrass\” or soursob. The roots, stems and leaves of Oxalis pes-caprae have high medicinal values and have the function of antiinflammatory and analgesia, clearing heat, removing toxicity. In present study Oxalis pescaprae belonging to family oxalidaceae evaluated for pharmacological activities like cytotoxicity, phtotoxicity, antibacterial and antifungal bioassays. Materials and Methods: Cytotoxic activity was performed by brine shrimp bioassay using methodology of Atta- ur- Rahman et al., 2001. The phytotoxic activity was investigated by applying Lamna minor (as test species) following Atta-ur-Rahman et al., 2001. Anti-bacterial screening was conducted following Rathan (2000). Anti-fungal screening was carried out using agar well diffusion method following Perez et al. (1990) and Atta-ur-Rahman et al. (1991). Results: Its ethanolic extract showed highly significant (100\%) cytotoxicity with LD50 8.98 at 1000 ppm. Lemna minor phytotoxicity assay showed that O. pes-caprae chloroform extract showed 90\% inhibition at 1000 ppm with FI50 0.1048. Antibacterial bioassays showed that all the samples of the plant were significant against Xanthomonas, Clavibacter machengnitis and Bacillus at 1000, 1500 and 2500 ppm doses. Dose dependent antifungal activities against test species (Aspergillus flavus, Penicillium and Fusarium solani) were noticed for all the extracts at 100 and 1000 ppm. Conclusion: Pharmacological potentials showed that this plant can be used in upcoming time for extracting numerous active constituents for their pharmacological preparations.

Background: Euphorbia dracunculoides L is available in market in raw form. It is used by people for the treatment of warts, snake bite and epilepsy. Present study is about Euphorbia dracunculoides L. belonging to the family Euphorbiaceae, comprises pharmacognostic study, physiochemical analysis and their pharmacological efficacy. Materials and Methods: The macroscopic study was carried out through sensory organs like size, shape, texture etc. Physiochemical analysis was carried out through proper procedure from relevant literature, and analgesic activity was done through proper method by following literature. Results: Macroscopic study showed that the plant is an annual herb, stem is branched from the base, yellow green at the bottom and light green at the top, glabrous, smooth, contains white latex, its leaves are sessile, alternate, dark green, simple, stipulated, sub-acute or acute at the apex and entire margin. Root is yellowish in colour, conical in shape, smooth texture, downward in position. Powder drug study which was performed revealed various structures. Phytochemical screening includes both qualitative and quantitative analysis which was carried out indicated the presence of carbohydrates, proteins, saponins, sterols, alkaloids, phenolic compounds, glycosides, flavonoids and tannins. Proximate analysis showed proteins, crude fat, crude fibre, carbohydrates, moisture contents and ash. Elemental analysis revealed the presence of macro and micronutrients i-e Na, Zn, Mg and Fe, Cu, Ag and Au. Analgesic effect was dose dependent. Plant extract showed maximum inhibition of writhing 1.66\±0.32 (96.61\%) at 300 \μg/ml. Conclusion: The pharmacognostic study, physiochemical analysis and their pharmacological efficacy is helpful in the standardization of drug.

Introduction: Eclipta alba Linn. (Asteraceae) is an important ingredient of several Ayurvedic formulations. The monograph on different parts of plant like flowers, leaves, roots are listed in Ayurvedic pharmacopeia of India. The plant is reported to be effective for broad range maladies like inflammation, reproductive problems of females etc. It is also used as a hepatoprotectant, analgesic, antibacterial and antidiabetic agent. Wedelolactone is used as a bioactive marker to establish the quality of the crude drug and its formulations. In the present study, wedelolactone-based standardization of Eclipta alba and its quantitation from marketed herbal and Ayurvedic formulations has been documented using RP-HPLC. Methods: In the current work, an isocratic method has been developed and validated to quantitate wedelolactone from whole plant of Eclipta alba. This method is validated as per ICH guidelines and is used to quantitate the content of wedelolactone in polyherbal formulations like Liv52, Geriforte, Mahabhringaraj oil etc. Results: The LOD is found to be 0.5 \μg/mL and the LOQ is 1 \μg/mL. The linearity range of response is from 5 \μg/mL to 100 \μg/mL. Conclusion: The validated method is found to be simple, sensitive, accurate, rugged and reproducible. This developed method can be recommended for quality assurance and marker-based standardization of polyherbal formulations containing whole plant of Eclipta alba.
