Search for cost-effective, safe and highly potent plant-based insecticides for the control of mosqu...

Phytochemical investigation of the 70% EtOH extract of the leaves of Alstonia scholaris afforded seven new monoterpenoid indole alkaloids: scholarisins I-VII (1-7), and three known compounds: (3R,5S,7R,15R,16R,19E)-scholarisine F (8), 3-epi-dihydro- corymine (9), and (E)-16-formyl-5α-methoxystrictamine (10). Structural elucidation of all the compounds was accomplished by spectral methods such a...

An investigation has been made about the vesicular arbuscular mycorrhizal fungi colonization in some medicinal plants Catharanthus roseus, C. pusillus, Wrightia tinctoria, Thevetia peruviana, Nerium indicum and Alstonia scholaris belongs to family Apocyanaceae were screened for the occurrence and association of VA mycorrhizal fungi. All the plants screened in the study harbored VA mycorrhizal f...

The need for an alternative drug for malaria initiated intensive efforts for developing new antimalarials from indigenous plants. The information from different tribal communities of northeast India along with research papers, including books, journals and documents of different universities and institutes of northeast India was collected for information on botanical therapies and plant species...
