To begin with, first of all thanks to All Mighty Allah for giving me the strength to successfully accomplish this goal. I am grateful to Prof. Dr. Robert Verpoorte for giving me the opportunity to do this Ph.D. research at Pharmacognosy department, Leiden University. The Higher Education Commission (HEC) of Pakistan is highly acknowledged for the financial support along with Netherlands Organization for International Cooperation in Higher Education (NUFFIC) for managing my scholarship and health insurance during my stay in Netherlands.

This work wouldn’t have been completed without remarkable support of Federica Maltese and Young Hae Choi. I heartily appreciate their guidance and help to understand NMR spectroscopy and multivariate data analyses. My sincere gratitude to all GRASP GRAPEs WINE colleagues, specially Dr. Maria Salomè Pais, Dr. Ana Maragrida Fortes, Dr. Andreia Figueiredo, Dr. Reinhard Tӧpfer, Dr. Eva Zyprian, Dr.

Martina Rex, and Dr. Joachim Kopka, for providing the samples and also for their kind support and help throughout my studies.

Working at Pharmacognosy department is an absolute pleasure. We have people from different countries, working in a friendly but professional and competitive environment.

My sincere thanks to all the members of Pharmacognosy department, especially to Muzamal, for his help and contribution related to bioactivity studies in this research, and to Jahangir and Nancy for some valuable discussions.

I am fortunate to have a nice Pakistani community in Leiden. Being away from my home and family for such a long time, I couldn’t ask better than this. I really appreciate the help and friendship of Aamir, Asghar, Faraz, Imran, Kamran, Khurram, Khurshid, Mr. & Mrs. Akram, Mr. & Mrs. Hasnain, Mr. & Mrs. Shahbaz, Mr. & Mrs. Tariq, Nadeem, Qamar, Shoaib, Soban, Sohail, Tayyab, Yahya, and other friends.

Back in Pakistan, I would like to thank my previous supervisor Dr. Saifullah Khan for his guidance and patience towards me when I know nothing about research. I really appreciate the help and support of my colleagues at International Center for Chemical and Biological Sciences (ICCBS) including Abdul Rehman, Asma, Dr. Bushra, Mariam, Naheed, Saifullah, Sheeba, Tabassum, and specially Hammad and Dr. Sikandar.

Last but certainly not the least; I really appreciate the support and encouragement of my family, specially my parents, to whom I owe everything.

Curriculum Vitae

Curriculum Vitae

Kashif Ali was born on 1st February, 1981 in Karachi, Pakistan. He got his early education in Karachi. In the year 2000, after passing his higher secondary school examination, he joined University of Karachi for his Bachelors degree (B.Sc.) in Physiology, with biochemistry and microbiology. In 2002, he started his Masters (M.Sc.) in Biotechnology and finished in 2005. During M.Sc., he worked on one year project based on tissue culture and molecular studies on ornamental plants. In 2006, he started working as junior research fellow at H.E.J. Research Institute of Chemistry where, apart from working on the in vitro propagation of ornamental and fruit plants, he focused on the enhanced production of valuable plant secondary metabolites using cell suspension cultures in combination with chemical elicitors. In 2007, he got the Overseas Scholarship offered by Higher Education Commission of Pakistan for the Ph.D. studies which bring him to Leiden University, The Netherlands. He started his Ph.D. research on project named Genomic Research-Assisted breeding for Sustainable Production of

quality GRAPEs and WINE (GRASP GRAPE WINE,

http://urgi.versailles.inra.fr/index.php/urgi/Projects/GRASP) involving NMR-based metabolomics of grapes and wine. The results of this research are presented in this thesis.

Different pre-analytical methods were compared and used for the metabolic profiling of five grape cultivars from Portugal in combination with multivariate data analyses.. The

Our results are in accordance with these findings, since as can be observed in Figure 6 the highest levels of different organic acids including citric, fumaric, tartaric

In ‘B’, samples are colored according to developmental stages where green represents green stage, blue represents veraison, black represent ripe, and red represents harvest

Organic acids like malic and tartaric acids were also found discriminating for the higher quality scores wine along with some phenolics like quercetin, (+)-catechin, and

As shown by the NMR spectra (Figure 1), the methanol fractions are rich in fatty acids and amino acids including alanine, threonine, valine, arginine, and glutamic acid while the

In this study, metabolite fingerprinting of crude leaf extracts, based on 1 H nuclear magnetic resonance (NMR) spectroscopy and multivariate data analyses, has been used

Metabolites responsible for their discrimination were identified as a fertaric acid, a caftaric acid, quercetin-3-O- glucoside, linolenic acid, and alanine in the resistant
