This study was undertaken to provide more scientific information about the phytochemical composition of Laggera crispata known for its medicinal uses. Essential oil was isolated by hydro-distillation, analysed using GC-MS, UV-Visible Spectrophotometer and other established biochemical assays were used for the study. The GC-MS analysis of the aerial essential oil of L. crispata showed the presence of 35 medicinal organic compounds making up 84.4\% of the oil. The most abundant component was a phenolic compound called 2-tert-Butyl-1,4-dimethoxybenzene (54.5\%). The other major terpenoids present in the oil were α-humulene (6.9\%) and (+)-sabinene (5.9\%). The TPC, TFC, TAA and TAC values of the aerial essential oil of L. crispata were 172.75{\textpm}0.00 μgmg-1 GAE, 48.69{\textpm}0.00 μgmg-1 QE, 61.85{\textpm}0.00 μgmg-1 AAE and 726.92{\textpm}0.00 μgmg-1 AAE respectively. DPPH IC50 and AAI values of the essential oil were 1.5 μgml-1 and 26.7. The essential oil displayed varying inhibitory activities against Gram-positive and Gram-negative bacteria with zones of inhibition ranging from 08-30 mm. The in vitro pharmacological activities added scientific support to the use of L. crispata in alternative and complementary medicine. The essential oil of L. crispata grown in Nigeria will play beneficial roles in human and animal health and therefore a research on this plant might be of great value in drug industries.

Objective: To elucidate cytotoxic activity of fractions from chloroform and methanol extracts of D. bulbifera organs on T47D breast cancer cells. Method: The vegetative organs of D. bulbifera were extracted gradually using chloroform and methanol. Cytotoxicity tested on T47D cells using MTT Assay. The most toxic extract was fractioned by vacuum liquid chromatography (VLC) followed by thin layer chromatography (TLC). The extract and fractions potential were tested on the Vero cells using the same method as cancer cells. The most toxic fraction was analyzed using TLC followed by the application of various spray reagents for the identification of active compound. Results: The chloroform extract of the D. bulbifera leaves was the highest cytotoxic on T47D cells (IC50 115.63\±86.01 \μg/mL). Moreover, the cytotoxicity test on the combined fractions of leaves chloroform extract showed that fraction 5 (F5) and fraction 6 (F6) were the most toxic fractions compared to those of other fractions. The IC50 of both fractions were 14.55\±8.62 and 7.12\±4.43 \μg/mL respectively. However, Its were very weak compared to those of cancer medicine (Doxorubicin) with the IC50 was 0.04\±0.02 \μg/mL. Potential fractions were not toxic against Vero cells with IS\>10. The active compounds in those fractions were alkaloid and terpenoid. Conclusion: Chloroform extract of the D. bulbifera leaves had the highest cytotoxic effect on T47D cells. Potential fractions were not toxic against Vero cells. The active compounds in those fractions were alkaloid and terpenoid.

Introduction: Endophytic fungi are becoming an important source of new natural bioactive products. Many interesting endophytic fungi have been isolated from traditional medicinal plants. Crocus sativus L. (saffron) is one of the most expensive and rarest spices in the world, used as a dye, aroma and for medicinal purposes. This study reports on the molecular characterization of endophytic fungi isolated from roots of saffron plants growing in Taliouine- Morocco, and the examination of the antibacterial and antioxidant activities of secondary metabolites extracted from these endophytes. Methods and Material: The fungi were isolated from sterilized saffron root fragments and identified using internal transcribed spacer (ITS) rRNA gene sequence analysis. Three endophytes were fermented and extracted with ethyl acetate (EtOAc) and chloroform (CHCl3). The antibacterial activity of fungi extracts was evaluated using the Agar Diffusion Method against six strains, Bacillus sp., Stenotrophomonas sp., Pseudomonas putida, Pantoea sp., Luteibacter sp. and Escherichia coli. The antioxidant activity was tested by using the \α,\α-diphenyl-\β-picrylhydrazyl (DPPH) analysis and \β-Carotene bleaching test (BCBT) methods. Results: Sixty fungal isolates were recovered and purified from saffron roots. ITS rDNA sequences were 99-100\% identical to three different species: Rhizopus oryzae, Aspergillus fumigatiaffinis and Aspergillus niger. Both Rhizopus oryzae extracts had high antibacterial activity against most of the bacteria tested, while Aspergillus niger and Rhizopus oryzae extracts showed an antioxidant capacity using DPPH and BCBT methods, respectively. Conclusion: The fungal endophytes inhabiting saffron roots could be a potential source of natural plant bioactive secondary metabolites especially for antibacterial and antioxidant purposes.
