Micropropagation of eclipta alba Eupatorium adelopsorum using a single - step nodel cutting techniqu
Get PDFProtocols for the micropropagation of two traditional medicinal plants Eclipta alba (L.) and Eupatorium adenophorum
(L.) from nodal segments were developed. Proliferated microshoots of Eclipta alba and Eupatorium
adenophorum were obtained through axillary branching by culturing nodal segments in modified MS medium and
half strength of MS, respectively, with minimal strength of nutritional support. Simultaneous rooting could also be
induced in the same medium. Regenerated rooted plantlets were successfully acclimatized in soil where they grew
normally without showing any morphological variatio

A facile threecomponent solid phase synthesis of steroidal Aring fused pyrimidines under microwave irradiation
Get PDFThe preparation of ringA
fused pyrimidines at the steroidal 2,3position
is herein described. The
novel steroidal pyrimidines were prepared from the solid phase threecomponent
reaction of 2hydroxymethylene3keto
steroids, arylaldehydes and ammonium acetate under microwave irradiatio
Hydrocarbon plant-New source of energy for future
Get PDFThe development of alternative sources for energy and chemicals, particularly the use of plant
biomass as a renewable source for fuel or chemical feedstocks, has received much recent attention.
This paper attempts to review the work carried out by many workers on evaluation of some plant
materials as source of energy and chemical feedstocks and the possibilities of producing hydrocarbon
and related chemical products, directly or indirectly. Also an exploratory work carried out at
Regional Research Laboratory, Jorhat is discussed. Some future directions, which need to be
considered to promote development of these petrocrops, are suggested
A long chain alkylated ;1-methylene-;3-butyrolactone from Artabotrys odoratissimus fruit
Get PDFAs part of our ongoing programme for isolation of bioactive molecules
from the flora of the Indo-Burma biodiversity belt, an unusual long chain
alkylated �-methylene-�-butyrolactone was isolated from the juice of
ripe fruit of Artabotrys odoratissimus R.Br. Its structure was determined
as 3-methylene-4-pentadecyldihydrofuran-2-one by spectroscopic
methods. It was found to have good antifungal activity against Alternaria tenuissima Kunze Ex Pers. isolated from solasodine producing plant Solanum khasianum Clarke. Minimum Inhibitory Concentration (MIC)and IC50 for 3-methylene-4-pentadecyldihydrofuran-2-one were found
as 300 and 51.37 ;Cg/ml, respectively. The standard captan was found
to have an MIC and IC50 of 200 and 35.52 ;Cg/ml, respectivel
