Abstract Endophytic fungi are the main source of natural compounds including pigments having various industrial applications. Present study describes the production of extracellular orange-brown pigment from an endophytic fungal isolate Aspergillus sp. N11from Teucrium stocksianum. The optimum conditions for pigment production from this isolate was investigated and results showed that highest yield was observed in Potato dextrose broth, at pH 5 and 30 ℃ under shaking condition at 150 rpm for 7-10 days. The pigment was extracted in ethyl acetate and purified using column chromatography. Three different pigments were purified (yellow, light brown and orange-brown) and characterized based on Thin layer chromatography and Fourier transform infrared spectroscopy. The antimicrobial activity of purified fragments showed maximum zone of inhibition of 40 mm against S. aureus while for P. aeruginosa maximum zone of 50 mm and maximum antifungal activity of 20 mm against C. albicans. The antioxidant potential of purified pigment obtained from Aspergillus sp. N11 indicates that maximum scavenging activity of 67%. The results showed that purified pigments are astaxanthins belonging to oxygen containing carotenoids. The purified astaxanthins showed antibacterial, antifungal and antioxidant activities indicating its potential to be utilized in pharmaceutical and food industries.

Abstract Background: Considering the positive and valuable upshots of the naturally occurring ingredients as the complementary treatment for many ailments, this study investigates the Teucrium Stocksianum Bioss Fixed Oil (FO) for the treatment of inflammation.Methods: Different plants of the Teucrium genera have been employed occasionally for the management of different disorders. Teucrium stocksianum (Lamiaceae) is traditionally use as antipyretic along with remedy of inflammation, diabetes and tumors. It also occupies the capacity to purify the blood. The aim of this study is to determine the chemical constituents and anti-inflammatory potentials of Teucrium stocksianum fixed oil (FO). Qualitative and quantitative analysis of fixed oil were performed via GC-MS (Gas Chromatography coupled with Mass Spectrometer). Preliminary inflammation antagonistic activity was calculated in mice using the carrageenan-induced paw edema model while the mechanism behind this inflammatory antagonistic effect was determined by employing various inflammogens including arachidonic acid, prostaglandins E2 and leukotriene via paw edema model.Results: The acute toxicity of fixed oil was determined at 3, 6 and 10 ml/kg body weight of the mouse. The GC-MS analysis documented 21 various unsaturated and saturated fatty acids elements. The methyl esters of octadecadienoic and linoleic acids were found predominantly at 22.60% and 23.84% respectively. In preliminary screening, FO demonstrated substantial anti-inflammatory capacity (67.87%, **P ˂ 0.01) in carrageenan induced paw edema model at 3 ml/kg body weight. The activity reached a peak value at the 3rd hour and continued persistent until the 5th hour of sample administration. FO displayed dose-dependent inhibition against all inflammogens at 3 ml/kg at 3rd h of the FO administration. These have shown marvelous protection i.e. 64.92%, 68.75%and 58.3% against arachidonic acid, prostaglandin E2 and leukotriene accordingly, at 3 ml/kg. The arachidonic acid antagonist (Caffeic acid) demonstrated 69.43% activity at 100 mg/kg after 3rd h of its administration while in the acute toxicity test, FO has shown no grass lethality at 10 ml/kg dose.Conclusion: According to our findings, the FO of T. stocksianum exhibits inflammation antagonistic potential through both lipoxygenase (LOX) and cyclooxygenase (COX) enzyme inhibition strategies that intensely sustenance the traditional practice of T. stocksianum in the management of multiple pathological inflammatory situations. The computed binding energies of the molecules exposed have synergistic potential to avert inflammation.

<p class="Abstract">The present study was aimed to evaluate the effect of <em>Teucrium stocksianum</em> on angiogenesis by using chorioallantoic membrane (CAM) assay. Fertilized eggs were incubated on the 5<sup>th</sup> day and dose of different dilutions 0.03%, 0.05%, 0.1%, and 0.5% of the plant extract was applied on 6<sup>th</sup> day. Evaluation of primary, secondary and tertiary blood vessels diameter and CAM area on 7<sup>th</sup> day by SPIP software. <em>T. stocksianum</em> showed antiangiogenic effect by reducing the diameter of CAM of blood vessels by applying the dilutions while significant results were obtained at dilution of 0.5%.</p><p> </p><p><strong> </strong></p>
