The aim of the present study was to investigate phytochemical and antibacterial potential of Calendula officinals L. and Catharanthus roseus L. G. Don leaves. The leaves of both plants were screened for physico-chemical analysis. Phytochemical screening was carried out to find phytoconstituents and subsequent antibacterial studies of extracts were carried out against the pathogenic bacterial strains Bacillus cereus, Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Salmonella typhi using Kirby bauer method. The extract with maximum antibacterial activity was further processed for TLC studies. The results of the present investigation revealed superiority of C. roseus over C. officinalis in terms of ash value. Both plants showed the presence of alkaloids, saponnins, tannins, phenolic compounds, flavonoids and carbohydrates. The antibacterial studies revealed that the petroleum ether extract of C. officinalis has been active against all strains, whereas the same extract of C. roseus showed activity against S. typhi, S. aureus and B. subtilis. Chloroform extract of C. officinalis was active against only two strains i.e. E. coli and B. subtilis. Methanolic and aqueous extracts of both plants were also found to be active against all strains. Studies of TLC analysis revealed that petroleum ether extract of C. officinalis and methanolic extract of C. roseus showed distinct RF values. Further studies are required to separate characterize and screen these components for therapeutic purposes.

‘Preliminary phytochemical analysis of successive extracts, fluorescence analysis and HPTLC of C. macleodiileaves has been planned in the current study.’ The extracts of the dried coarse powdered of C. macleodii leaves obtained using different polarities solventsin succession were tested for the presence of various active phytoconstituents. Fluorescence analysis was investigated andunsaponifiable fraction of petroleum ether extract was also observed forchromatographic evaluations. The outcome suggest that the existence of various dynamic phytoconstituents having particular solubility in selected solvents of different polarities used in succession. The fluorescent analysis under the visible and UV light by treatment of diverse chemical reagents showed diverse colours. HPTLC profile of unsaponifiable fraction showed 10 and 3 spots at 254 nm and 366 nm radiation respectively. After spraying with diluted H2SO4, it showed 5 and 6 spots at 254 nm and 366 nm radiations respectively. The presence of active constituents in different polarities solvent, which were used in progression suggesting the significance of the solvent as a conclusive factor. Further the data suggests that, the successive extractions using Petroleum ether, chloroform, methanol and water solvents of different polarities would maximize the exploitation of the diverse bioactive compounds. Study concluded that it would be help to isolate and characterize the different pharmacologically dynamic principles of the C. macleodii such as mouth sores, treating jaundice, hepatoprotective and also as an aphrodisiac.

AbstractThe phytochemical and antimicrobial activity of the petroleum ether and crude methanol extracts, chloroform and ethyl acetate fractions of the leaves of Lannea kerstingii were investigated. Phytochemical screening revealed the presence of steroids and triterpenes in the petroleum ether extract, steroid, triterpene, flavonoids and tannins in both crude methanol extract and chloroform fraction while the ethyl acetate fraction contained only flavonoids and tannins. The extracts exhibited antimicrobial activities with zones of inhibition ranging from 17.00 to 21.03, 20.10 to 25.24, 25.32 to 34.02 and 22.28 to 27.20 mm for petroleum ether extract, methanol extract, chloroform and ethyl acetate fractions respectively. The minimum inhibitory concentration was between 5 and 10mg/ml, 5mg/ml for the petroleum ether and methanol extract respectively, and between 2.5 and 5 mg/ml, 5mg/ml for the acetate fractions. The minimum bactericidal concentration for all the extracts was 40mg/ml respectively except for chloroform fraction which ranged from 20 to 40mg/ml. The minimum fungicidal concentration for all the extracts was found to be 40mg/ml respectively. This result indicates the broad spectrum antimicrobial potential of L. Kerstingii and justifies the use of this plant in traditional medicine.
