Abstract :
Biochemical Evaluated of some bio extracts as follows: Chemical composition and Phytochemical screening were determined in Tilia Cordata and Vitex Agnus leaves. The total polyphenols and flavonoids contents of Tilia Cordata leaves have the highest of total polyphenols and flavonoids contents, which were 126.00mgGAE/g and 15.88mgQE/g, followed by Vitex Agnus leaves, which were 119.77mgGAE/g and 13.41mgQE/g, respectively. Methanolic and aqueous extracts of plants leaves were antioxidant activity by used (FRAP, LPO, DPPH and ABTS) The methanolic extract of Tilia Cordata and Vitex Agnus leaves, have the highest of reducing power which were 1.649 and 1.018 at the concentrations of 80mg/ml, respectively. Also, by used (LPO, DPPH and ABTS), were the highest antioxidants activity for methanolic extract respectively. Moreover, the methanolic extract of Tilia Cordata leaves produced the highest growth inhibition (18 and 17mm) for against Escherichia coli and Bacillus subtillis at 4mg/ml, respectively. While, The methanolic extract of Vitex Agnus produced the medium percentage of growth inhibition (10.5, 9.75 and 10mm) for against Escherichia coli, St.coccus aureus and Bacillus subtillis at 4mg/ml, respectively. And compared with antibiotic. This study concluded that Tilia Cordata and Vitex Agnus leaves extract has an antioxidant and antibacterial activity.
Keywords: Chemical composition, Phytochemical, Antioxidant and Antibacterial activity.

Abstract:
Thirty-eight soil samples were collected from different sites in Thamar province during the period from 4/2012 to 2/2013.The direct plate, and dilution plates methods were followed to isolation of counting colony forming units, the potato carrot agar (PCA) and Emerson’s media were used A total of 23 fungi belong to (14) genera were isolated, they include (11) Hyphomycetes, (10) Ascomycetes, and (2) Zygomycetes besides black and white sterile mycelium. A fourteen isolates were regarded asnewly record for Yemeni mycobiota,they include Acremonium murorum, Acrophialophorafusispora, Chaetomiumatrobrunneum, C.gracile,C.strumarium, C.therophilevar.coprophpile, Corynascussepedonium ,Emericellarugulosa, Melanocarpusalbomyces, paecelomycesinflatus Papulosporathermophila, Rhizomucormiehi, Scytalidiumthermophilum, and Talromycesthermophilus Soil dilution method showed that the colony forming units (CFUs)in soil had seasonal fluctuation , they were significantly higher (36667) during moderate/humid month than cold/dry months (20400) (p<0.05), while the total similarity% is high between fungal genera which were isolated during the two periods (78.57%) .A test of 15 isolates to produce cellulase, amylase, lipase, protease, xylanase and phenoloxidase showed a different activities in number of enzymes and levels of production. Corynascussepedonium, Eemericellanedulans and Malbrancheacinnamomea gave a positive result for all enzymes
