3 Department of Chemistry, Gurukula Kangri Vishwavidyalaya, Haridwar, Uttarakhand, (India) ABSTRACT In the present study the effect of maceration and soxhlet extraction from plant leaves of Casearia tomentosa were compared for phytochemical screening and antioxidant activity using petroleum ether as solvent. The phytochemical screening was evaluated using standard protocols and the antioxidant ...

Terpenoids are important for plant survival and also possess biological properties that are beneficial to humans. Here, we describe the state of the art in terpenoid metabolic engineering, showing that significant progress has been made over the past few years. Subcellular targeting of enzymes has demonstrated that terpenoid precursors in subcellular compartments are not as strictly separated a...

Electrophysiological responses of adult males and females of C. carnea to commonly occurring plant volatiles were recorded using the electroantennogram technique. Responses to 28 volatiles evaluated indicate that both depolarization and recovery to the baseline were rapid in females compared to males. Normalized EAG responses relative to the standard, trans-caryophyllene reveal significant diff...

The free radical scavenging activities of n-hexane extract of the whole plant of Emilia sonchifolia was evaluated by employing various in vitro assay systems like DPPH radical scavenging activity, superoxide radical scavenging activity and hydrogen peroxide scavenging activity with IC50 values 180, 160 and 160 μg/ml respectively. The results of the study indicate that the n-hexane extract of th...

To overcome the potential future demand for terpenoids used as drugs, a new production platform is currently being established in our laboratory. The moss Physcomitrella has been chosen as the candidate organism for production of drug candidates based on terpenoids derived from plants, with a primary focus on the sesquiterpene lactone, thapsigargin. This drug candidate and other candidates/drug...

Spices have been added to foods since ancient times, not only as flavoring agents, but also as folk medicines and food preservatives. The current investigation deals with the extraction and phytochemical analysis of Syzygium aromaticum, Piper nigrum and Cinnamomum verum which are one of the most important spices used in India. The presence of phytochemicals including phytosterols, saponins, alk...
