Raj1, A. Balasubramaniam2, Sayyed Nadeem2 1Department of Pharmacy, Karpagam University,Coimbatore, Tamilnadu, – 641021, India 2Technocrats Institute of Technology- Pharmacy, Bhopal, M.P.-462021, India ABSTRACT Parkinson’s disease (PD) is one of the neurodegenerative diseases with selective loss of dopamine neurons of the substantia n igra pars compacta. In the present study, anti-cataleptic activity of Tabernaemontana divaricata leaves extracts viz. aqueous and ethanolic at different doses (50, 100 and 150 mg/kg i.p.) were studied using haloperidol (1 mg/kg, i.p.) induced catalepsy in rats which is a useful animal model for screening drugs for Parkinson’s disease. Both the extracts were found to reduce catalepsy significantly (P<0.001) as compared to the haloperidol treated rats showing greater effect at 150 mg/kg i.p. dose. Thus the present study reveals the anti- cataleptic activity of Tabernaemontana divaricata evaluating the traditional folklore medicinal use of the plant. Key Words: Tabernaemontana divaricata, Parkinson’s disease (PD), catalepsy, haloperidol, bar test.

(Apocynaceae) is a traditional medicinal T Y H • R plant in Middle East and South Asia. It contains a large number of G I E L S H 93 E G terpenoid indole alkaloids (TIAs), some of which possess A I R H C interesting pharmacological properties. This study was focused on H biotechnological production tools of R. stricta, namely undifferentiated cell cultures, and an Agrobacterium rhizogenes- mediated transformation method to obtain hairy roots expressing heterologous genes from the early TIA pathway. Rha zya alkaloids comprise a wide range of structures and polarities, therefore, many A analytical methods were developed to investigate the alkaloid l k contents in in vitro cultures. Targeted and non-targeted analyses a l o were carried out using gas chromatography-mass spectrometry i d (GC-MS), high performance liquid chromatography (HPLC), ultra s o performance liquid chromatography-mass spectrometry (UPLC- f i MS) and nuclear magnetic resonance (NMR) spectroscopy. n Calli derived from stems contained elevated levels of v i t r strictosidine lactam compared to other in vitro cultures. It o was revealed that only leaves were susceptible to Agrobacterium c u infection and subsequent root induction. The transformation l t u efficiency varied from 22% to 83% depending on the gene. A total r e of 17 TIAs were identified from hairy root extracts by UPLC-MS. -

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.

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. -

2308 J.C.S. Perkin I The Biosynthesis of Monoterpenoid lndole Alkaloids from Strictosidine By Naotaka Nagakura, (Mrs.) Martin8 Ruffer, and Meinhart H. Zenk," Lehrstuhl fur Pflanzenphysiologie, Ruhr-Universitat Bochum, D 4630 Bochum, W. Germany The differential incorporation of doubly labelled strictosidine and vincoside into several indole alkaloids belonging to the Corynanthe (3a and 3p series), Aspidosperma, and lboga types in three plant families has been studied, and it has been demonstrated that only strictosidine is incorporated while vincoside is metabolically inert in these plants with regard to alkaloid formation. During the conversion of strictosidine into the 3P-indole alkaloids, the hydrogen atom at the 3-position is lost, while it is retained during the biosynthesis of the 32 alkaloids. The chemical synthesis of [7-3H]secologanin, an important intermediate for further work in the biosynthesis of monoterpenoid alkaloids, is also described. THEfundamental research of Battersby and Arigoni and (S)-3a stereochemistry, is indeed the key intermediate their associates during the past decade has established in the formation of the three classes of monoterpenoid the central role of loganin and secologanin (2) in the indole alkaloids (Asfiidosfierma, Iboga, and Corynanthe) biosynthesis of a multitude of monoterpenoid indole in Catharanthus roseus (syn. Vinca rosea) plants as well alkaloids. Secologanin (2) is the ultimate precursor for as a variety of other species in cell cultures by in vivo the C-9/C-10 non-tryptamine carbon skeleton -

Isohtion of Alkaloids and Structural Identification of Two Dimers
Indole Alkaloids from Ervatamia ouientaiis. I Isohtion of Alkaloids and Structural Identification of Two Dimers ., John R. Knox and Jacob Slobbe I 9 1;:’ ,di Department of Organic Chemistry, University of Western Australia, ,;,, ,A>.i I Nedlands, W.A. 6009. Abstract Ethanol extracts of Eruafamia orientalis have yielded the following known alkaloids: ibogaine, iboxygaine, voacristine, vobasine, dregamine, tabernaemontanine, apparicine, voacamine and 16-demethoxycarbonylvoacamine. In addition, two new dimeric alkaloids of the voacamine group and the novel 2-acylindoles ervatamine, 2O-epiervatamine and 19-dehydroervatamine have been isolated from the extracts. The two new dimeric compounds have been identified by physical and chemical methods as lddemethoxycarbonyldihydrovoacamine and 16-demethoxycarbonyl-20’-epi- dihydrovoacamine. Plants classified in the Tabernaemontaneaetribe (Apocynaceae) have proved to be a rich source of indole alkaloids. ’ The tribe is the sole plant source of the iboga type alkaloids (with one exception’), the related voacamine group of dimeric alkaloids and the vobtusine group of dimeric alkaloids; it is also an important source of the 2-acylindole class and has afforded miscellaneousother types of indole alkaloids.1*3r4 The second largest of the 20 genera in the tribe is Eruatamia’ but rela- tively few of the 92-95 species in the genus have been examined for alkaloids. Iboga- type alkaloids have been obtained from E. dichotoma (coronaridine,6 heyneanine,’ voacristine hydroxyindolenine’), E. coronaria (coronaridine, voacangine’) and E. pandacaqui (coronaridine”), 2-acylindoles from E. coronaria (dregamine, tabernae- montanine’), E. divaricata (tabernaemontanine”) and E. pandacaqui (tabernae- montanine”) and aspidospermine types from E. dichotoma (tabersonine”) and E. dioaricafa (lochnericine, voaphylline”). E. pandacaqui has also afforded 20-epilochneridine and three dimeric alkaloids (ervafoline, ervafolidine, isoerva- r Hegnauer, R., ‘Chemotaxonomie der Pflanzen’ Vol.
