Tabernaemontana L. (Apocynaceae): a review of its taxonomy, phytochemistry, ethnobotany and pharmacology.
The taxonomy, phytochemistry, ethnobotany, and pharmacology of the genus Tabernaemontana L. (Apocynaceae) is reviewed and the biogenesis and classification of the indole alkaloidal species is set out and some problems in the determination of their stereochemistry are discussed. Expand
Antimicrobially active alkaloids from Tabernaemontana chippii.
All the dimeric alkaloids from Tabernaemontana chippii root bark were shown to possess strong antimicrobial activity against gram-positive bacteria and moderate to weak activity against Gram-negative bacteria. Expand
Production of essential oils and flavours in plant cell and tissue cultures. A review
The production of essential oils and flavours by plant cell and tissue cultures is reviewed, including the biotransformation of added precursors. Methods which have been employed to increaseExpand
Studies on Indonesian medicinal plants
Five species of Menispermaceae collected in Indonesia have been screened for their alkaloid content. Magnoflorine has been isolated fromPycnarrhena novoguinensis andCyclea barbata.
Antimicrobial, antiamoebic and antiviral screening of some Tabernaemontana species.
The antibacterial, antifungal and anti-yeast activities of ethanolic extracts of 19 different TABERNAEMONTANA species have been screened by means of the agar diffusion test, and only two of the 14 species examined for antiviral activity showed significant activity against a single virus. Expand
Trifluoroacetic acid, A 1H-NMR shift reagent for alkaloids
Acidic impurities may change the 1H-NMR spectra of alkaloids drastically. The acid-induced shifts might be a useful tool in the structure elucidation of alkaloids.
