| Abstract | Antifungal activities of five plant species (Thymus vulgaris, Lavandula vera, Menta viridis, Rosmarinus officinalis and Cassia italic) extracts were tested against Rhizoctonia solani using three different solvents (methanol, acetone and chloroform). Using linear growth technique, the percentages of growth inhibition caused by extracts were determined. The methanol extracts of all test plants were the most effective to inhibit the mycelial growth of test fungus. The percent of growth inhibition of R. solani was least affected by the chloroform extract. Whereas, at 8 % concentration, methanol extracts of R. officinalis and T. vulgaris caused complete (100 %) inhibition of R. solani growth. Similar results for M. viridis were attained only at 10 % concentration, compared to control treatment. The analysis of High performance liquid chromatography of five plants indicated that, the extraction with different solvents will lead to different types and concentrations of phenolic compounds.Se probaron extractos para actividad antifungica de cinco especies vegetales (Thymus vulgaris, Lavandula vera, Menta viridis, Rosmarinus officinalis y Cassia italic) contra Rhizoctonia solani, utilizando tres solventes diferentes (metanol, acetona y cloroformo). Con la utilización de la técnica de crecimiento lineal se determinaron los porcentajes de inhibición del crecimiento causada por los extractos. Los de metanol de todas las plantas probadas fueron los mas efectivos para inhibir el crecimiento micelial del hongo a prueba. El porcentaje de la inhibición del crecimiento de R. solani fue menos afectado por el extracto de cloroformo. Mientras que a 8 % de concentración, los extractos de metanol de R. oficinalis y T. vulgaris causaron inhibición completa (100 %) del crecimiento de R. solani. Se obtuvieron resultados similares con M. viridis solo a 10 % de concentración, comparados con el tratamiento testigo. El análisis de cromatografía líquida de alta resolución de las cinco plantas indicó que la extracción con distintos solventes conducirá a diferentes tipos y concentraciones de compuestos fenólicos. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
