Email: [email protected] Received: 01 March 2016, Revised and Accepted: 29 January 2018 ABSTRACT Plants in the genus Tabernaemontana have been using in Thai and Chinese traditional medicine for the treatment several diseases. The great majority constituents of Tabernaemontana species have already been subjected to isolation and identification of monoterpene indole alkaloids present in their several parts. Many of monoterpene indole alkaloids exhibited a wide array of several activities. The biogenesis, classification, and biological activities of these alkaloids which found in Tabernaemontana plants were discussed in this review and its brings the research up-to-date on the bioactive compounds produced by Tabernaemontana species, directly or indirectly related to human health.

All monoterpene indole alkaloids are derived from aromatic amino acid tryptophan and the iridoid terpene Several already drugs were discovered from the natural products. secologanin (Scheme 1). Tryptophan converts to tryptamine using Especially, the treatments of infectious diseases and oncology have tryptophan decarboxylase which is a pyridoxal-dependent enzyme. benefited from numerous drugs which were found in natural product The specific iridoid precursor was subsequently identified as sources. -
Gastroprotective Effect of Tabernaemontana Divaricata (Linn.) R.Br

Received 24th April 2011 Accepted 2nd June 2011 Research Article Online Ready 6th June 2011 ABSTRACT Tabernaemontana divaricata (L.) R.Br belonging to Apocynaceae family is traditionally used by people in many parts of the world to treat various disorders. The present study was undertaken to investigate anti-ulcer property of Tabernaemontana divaricata flower methanolic extract (TDFME 500 mg/kg, p.o) by pyloric ligation induced gastric ulceration model using Omeprazole (8mg/kg, p.o) as a standard drug in wistar rats. Five parameters i.e., volume of gastric juice, pH, free & total acidities and ulcer index were assessed. The test extract significantly (p< 0.01) decreased volume of gastric juice, free & total acidities and ulcer index. Like standard, it also raised pH of gastric acid. The observed percentage protection for standard and test were 89.84% and 79.53%, respectively. Thus, TDFME 500 mg/kg had a positive effect on all the parameters under study and the results were similar to that of standard. From the above results, it can be concluded that TDFME exhibits remarkable gastroprotective effect. -

Biosynthesis by in Situ Hybridization (ISH)
Localization of monoterpenoid indole alkaloid (MIA) biosynthesis by in situ hybridization (ISH) By Elizabeth Edmunds, Hons. B.Sc. A Thesis Submitted to the Department of Biotechnology In partial fulfillment of the requirements For the degree of Masters of Science August, 2012 Brock University St. Catha rines, Ontario ©Elizabeth Edmunds, 2012 ii Acknowledgments First and foremost I would like to thank Dr. Vincenzo Deluca for the opportunity to work in his laboratory under his mentorship. I have appreciated the helpful insight that has guided me through the course of this project. I have gained a valuable experience being able to learn from such an established and knowledgeable researcher. Secondly, I would like to thank my committee members Dr. Jeffrey Atkinson and Dr. Heather Gordon for their support and advice and their time to serve on my advisory committee. Thirdly, I would like to thank my colleagues and co-workers for their patience and helpful advice throughout my project. Particular mention must be given to Dr. Carlone's lab for their assistance and insight into in situ hybridization techniques. Finally, I would like to express my sincerest gratitude and appreciation towards my family and friends for their support. I would not be where I am today without the support and love from my mother and father, as well as Craig Easton. iii Abstract Monoterpenoid indole alkaloids (MIA) are among the largest and most complex group of nitrogen containing secondary metabolites that are characteristic of the Apocynaceae plant family including the most notable Catharanthus roseus. These compounds have demonstrated activity as successful drugs for treating various cancers, neurological disorders and cardiovascular conditions. -
