Pollen morphology of 18 species from the genus Impatiens collected different localities in Nilgiris, Tamil Nadu was evaluated using scanning electron microscopy (SEM) during period February 2017 to November 2019. From observation pollen it found be structurally monad; prolate, sub-prolate and prolate-spheroidal equatorial view; circular, rectangular, triangular, quinquangular, elliptic quadrangu...

This study investigates the variations in chemical profiles and biological activities (antioxidant cytotoxic) of Eplingiella fruticosa from state Sergipe, an endemic species Northeast region Brazil. The essential oils were extracted six populations by hydrodistillation analyzed GC/MS-FID. Cluster analysis was performed with data constituents oils, then a dissimilarity matrix, based on Euclidean...

The anticancer activities of two Lebanese plant extract Micromeria fruticose (A) and Teucrium polium (B) their fractions were tested against MCF7 A549 cancer cell lines using MTT assay. Separation was carried out through column chromatography TLC analysis. Results showed that both plants possess a promising dose dependent inhibitory activity with IC50of A 28.52 26.47 μg/ml on cells respectively...

The phylogenetic relationships within the genus Betula (Betulaceae) were investigated using a part of the nuclear ADH gene and DNA sequences of the chloroplast matK gene with parts of its flanking regions. Two well-supported phylogenetic groups could be identified in the chloroplast DNA sequence: one containing the three American species B. lenta, B. alleghaniensis, and B. papyrifera and the ot...

Received 10 September 2013 Received in revised from 17 September 2013 Accepted 22 October 2013 Available online 25 October 2013 ABSTRACT The efficancy of synthetic insecticides in vector control has been reduced. This leads to the search of insecticides of botanical origin which can serve as a suitable alternative biocontrol technique. Many plants have been reported to have mosqitocidal activit...

The development of anthelmintic resistance and high cost of conventional anthelmintic drugs led to the evaluation of medicinal plants as an alternative source of anthelmintics. Traditional medicines act as a source of easily available effective anthelmintic agent. In the current study, In vitro experiments were conducted on Indian adult earthworms (Pheretima posthuma) to determine the possible ...
