Metabolic constituents of grapevine and grape-derived products
Important metabolites from grapevine and grape derived products like wine will be reviewed with their health promoting effects and their role against certain stress factors in grapevine physiology.
Monitoring biochemical changes during grape berry development in Portuguese cultivars by NMR spectroscopy
Transcript and metabolite analysis in Trincadeira cultivar reveals novel information regarding the dynamics of grape ripening
Several genes were identified that had not been previously reported in the context of grape ripening namely genes involved in carbohydrate and amino acid metabolisms as well as in growth regulators; metabolism, epigenetic factors and signaling pathways.

Grapevine (Vitis vinifera ssp. vinifera L.) and grapes have been extensively studied due to their numerous nutritional benefits and health affecting activities. In this study, metabolite…
DIRECT ORGANOGENESIS OF KALANCHOE TOMENTOSA (CRASSULACEAE) FROM SHOOT-TIPS
An efficient and cost effective protocol for direct regeneration of Kalanchoe tomentosa, a valuable medicinal and ornamental plant, is presented here and it is suggested that there is a little role of plant growth regulators in the In vitro development, multiplication and organogenesis of K. toMENTosa.

It can be postulated the NMR-based metabolomics offers an easy and comprehensive analysis of wine and in combination with multivariate data analyses can be used to investigate the source of the wines and to predict certain sensory aspects of wine.
IN VITRO PROPAGATION OF CROTON (CODIAEUM VARIEGATUM)
An improved and enhanced method was established for the In vitro propagation of croton by using MS media supplemented with 2.0 mg/L of IBA (Indole 3- butyric acid) and adding adjuvants like malt extract and peptone.
Efficacy assessment of diatomaceous earth against Callosobruchus maculatus (F.) (Coleoptera: Bruchidae) on gram at different temperature and relative humidity regimes
The results showed that all treatments were highly effective against the bruchids; however, the highest mortality was observed at 30°C and 50% relative humidity at 800 ppm of DE with minimal progeny production.
NMR spectroscopy and chemometrics as a tool for anti-TNFα activity screening in crude extracts of grapes and other berries
This work demonstrates the great potential of NMR spectroscopy in combination with chemometrics for the screening of large set of crude extracts, to study the effects of different variables on the activity, and identifying active compounds in complex mixtures like plant extracts.
