The active substances were in most cases antibacterial and only 3 possessed antifungal activity.
Thirty-three species were inhibitory to gram-positive bacteria alone, 9 exclusively against gram-negative bacteria and 15 to both.
The results showed that in vitro treatment of fungi by the essential oil led to hyphae disruptions and changes in the fungal spore shapes.
The studies on the antimicrobial activity showed high growth inhibition for when challenged with concentrated oil extract.

Evaluation of the anti-nociceptive potential of ethanolic extract of leaves of Bryophyllum pinnatum in experimental animals. MATERIALS AND METHODS Sample collection: Healthy seeds of C. Preparation of seed extracts: Each plant seed sample was washed and air dried at ambient temperature (25°C). Approximately 0.5 m L of the previously prepared inoculum of the dilute cultures was aseptically inoculated onto the surface of sterile Petridishes containing sterile solid nutrient agar. These results were consistent withthose reported by other researchers Figure 3 shows that the zone of inhibition for the hexane and ethanol extracts of J. However, the lowest zone of inhibition (0.60±0.012 mm) was shown with the water extract against B. Generally, the different seed extracts revealed a concentration-dependent inhibition effect on the bacteria tested. Cytotoxicity, mutagenicity and antimicrobial activity of forty Jordanian medicinal plants. The plants were extracted in water, methanol, 70% ethanol, acetone and ether and assayed against 3 gram-positive, I acid-fast and 5 gram-negative bacteria and 3 fungal plant pathogens.Sixty-seven ferns and 6 fern allies, representing 64% of the samples examined, were antibiotic ally active.The sample was then ground into a powder using a mortar and pestle and kept in dark, airtight bottles for the extraction process. The same quantities of the powdered seed material were again percolated with ethanol and hexane, following the same method, in order to obtain three extracts per sample, namely, water, ethanolic and hexane extracts. Discs (6 mm diameter) impregnated with the seed extracts (water, ethanol andhexane) were aseptically placed onto the agar surface and thereafter incubated at 37°C for 24 h. aureus showed the same zone of inhibition (ZI) (1.0±0.0) against hexane extracts (50%) (Fig. Interestingly, the ethanol and hexane solvent extracts (50 and 30%) showed against E coli (5.9±0.10 mm). The lowest zone of inhibition (ZI) was found with the water extract (50%) against S. curcas was significantly higher (1.8±0.02 and 1.3±0.02 mm) against E. Based on the results obtained, both ethanol and hexane extracts showed different rates of inhibitory effect on both gram-positive and gram-negative bacteria. All the extractions were conducted by following the methods of Okorondu et al. Approximately 10, 30 and 50 g of the powdered Carthamus, Moringa and Jatropha seeds were percolated into 100 m L water and kept for 24 h. The inhibition zone was observed and then recorded in millimeters using a transparent meter ruler. Statistical analysis: The experiments were performed in a completely randomized design. In the same manner, the hexane extract inhibited E. It is hoped that these results will lead to the identification of compounds that could help to establish antibacterial drugs from natural products.

Five other species of Dryopteris showed remarkable antibacterial activity.The ferns of “Adiantum group” were found to be particularly active against gram-positive bacteria.
