Compatibility Analysis of Mushroom with different Botanicals in In vitro Condition

White button mushroom [Agaricus bisporus (Lange) Imbach] is the most popular cultivated edible mushroom, fetching high price and still dominating in Indian and International market. However, the limiting factor for its successful cultivation is the occurrence of competitor moulds. The present investigations were carried out in the laboratory Department of Plant Pathology, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh. In this experiment different botanical (seed extract) viz., Trachyspermum ammi (Ajwain), Foeniculum vulgare (Saunf), Anethum graveolens (Soa), Trigonella foenumgraecum (Methi) were evaluated to test their compatibility with Agaricus bisporus. The botanicals (seed extract) were evaluated in vitro through poison food technique at 10, 20 and 30% concentrations and 24, 48 & 72 hours of incubation. The maximum radial growth of Agaricus bisporus was observed in T0-Control (Agaricus bisporus) (16.45mm), (17.12 mm) and (17.22 mm) and minimum in T1 - Trachyspermum ammi (Ajwain) (1.46mm), (0.83mm) and (0.60mm) at 10, 20 and 30 percent concentration respectively. Maximum percentage of inhibition was observed in T1 - Trachyspermum ammi (Ajwain) (91.11%), (95.13%) and (96.50%) at 10, 20 and 30 percent concentration respectively.

Stereological assessment of nephroprotective effects of Trachyspermum ammi essential oil against carbon tetrachloride-induced nephrotoxicity in mice / Evaluación estereológica de los efectos nefroprotectores del aceite esencial de Trachyspermum ammi contra la nefrotoxicidad inducida por tetracloruro de carbono en ratones

Trachyspermum ammi (T. ammi) has been used in folk medicine as anti-inflammatory, antipyretic, antibacterial, antifungal agent. The present study was conducted to investigate the protective effect of Trachyspermum ammi (T. ammi) essential oil against CC14- induced nephrotoxicity in mice. Thirty-five mice were divided into five groups as follows; positive control received olive oil 1 mL/ kg/ip, negative control received CC14 1 mg/kg/ip + 0.5 mL distilled water orally and tree treatment groups which received CC14 similar to the negative control and 200, 800 and 1600 µg/kg of T. ammi essential oil, respectively. All treatments were done twice a week (Saturday and Wednesday) for 45 days. On the last day, blood was sampled for urea and creatinine assessment and the left kidney was removed for stereological estimations. Essential oil of T. ammi at high dose significantly (p ≤ 0.05) decreased serum levels of creatinine and urea in comparison with CC14-treated group. Total volume of the kidney, cortex, proximal convoluted tubules (PC), glomerulus, vessels and interstitial tissue as well as total length of PC and vessel were significantly (p ≤ 0.05) increased following CC14 administration and were restored toward normal levels at high dose of T. ammi. Also, high dose of T. ammi improved glomerular loss significantly (p ≤ 0.05) as compared with CC14-treated group. Due to the chemical composition of T. ammi essential oil such as tymol, p-cymene, γ-terpinene which are antioxidant, it can be concluded that the essential oil of T. ammi can ameliorated renal injury induced following CC14 toxicity via its antioxidant components.

En la medicina popular se ha utilizado el aceite esencial de Trachyspermum ammi (T. ammi) como agente antiinflamatorio, antipirético, antibacteriano y anti fúngico. El presente estudio se realizó para investigar el efecto protector de Trachyspermum ammi (T. ammi) aceite esencial contra la nefrotoxicidad inducida en ratones. Treinta y cinco ratones fueron divididos en cinco grupos de la siguiente manera; el control positivo recibió 1 mL / kg / ip de aceite de oliva, el control negativo recibió 1 mg / kg / ip + 0,5 mL de agua destilada por vía oral y grupos de tratamiento arbóreo que recibieron un control similar al negativo y 200, 800 y 1600 mg / kg de T. aceite esencial de T. ammi, respectivamente. Todos los tratamientos se realizaron dos veces por semana (sábado y miércoles) durante 45 días. En el último día de tratamiento, se tomaron muestras de sangre para evaluar la urea y la creatinina, y se extrajo el riñón izquierdo para realizar estimaciones estereológicas. El aceite esencial de T. ammi a dosis altas significativamente (p ≤ 0,05) disminuyó los niveles séricos de creatinina y urea en comparación con el grupo tratado. El volumen total del riñón, la corteza, los túbulos contorneados proximales (PC), el glomérulo, los vasos y el tejido intersticial, así como la longitud total de la PC y el vaso aumentaron significativamente (p ≤ 0,05) después de la administración y se restablecieron a niveles normales con dosis altas de T. ammi. Además, una dosis alta de T. ammi mejoró significativamente la pérdida glomerular (p ≤ 0,05) en comparación con el grupo tratado. Debido a la composición química del aceite esencial de T. ammi como timol, p-cimeno, 𝛾-terpineno con propiedades antioxidantes, se puede concluir que el aceite esencial de T. ammi puede mejorar la lesión renal inducida después de la toxicidad a través de sus componentes antioxidantes.

Monoterpene isolated from the essential oil of Trachyspermum ammi is cytotoxic to multidrug-resistant Pseudomonas aeruginosa and Staphylococcus aureus strains

Abstract INTRODUCTION: The aim of this study was to determine whether an herbal extract containing monoterpene exhibited activity against multidrug-resistant Staphylococcus aureus and Pseudomonas aeruginosa isolated from clinical infection samples. METHODS: The essential oil of Trachyspermum ammi (L.) Sprague ex Turrill (Apiaceae) fruit was extracted by hydrodistillation. Fruit residues were treated with hydrochloric acid and re-hydrodistilled to obtain volatile compounds. Compounds in the distilled oil were identified using gas-chromatography (GC) and GC-mass spectrometry (MS). The antibiotic susceptibility of all bacterial isolates was analyzed using both the disc diffusion method and determination of the minimum inhibitory concentration (MIC). The sensitivity of antibiotic-resistant isolates to essential oil was also determined by using the disc diffusion method and MIC determination. RESULTS: Of 26 clinical isolates, 92% were multidrug-resistant (MDR). Aromatic monoterpenes (thymol, paracymene, and gamma-terpinene) were the major (90%) components of the oil. Growth of S. aureus strains was successfully inhibited by the oil, with an inhibitory zone diameter (IZD) between 30-60mm and MIC <0.02μL/mL. The oil had no antimicrobial activity against clinical isolates of P. aeruginosa; rather, it prevented pigment production in these isolates. CONCLUSIONS: This study revealed that the essential oil of Trachyspermum ammi, which contains monoterpene, has good antibacterial potency. Monoterpenes could thus be incorporated into antimicrobial ointment formulas in order to treat highly drug-resistant S. aureus infections. Our findings also underscore the utility of research on natural products in order to combat bacterial multidrug resistance.
