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 increase… Expand
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.
Medicinal and Aromatic Plants in the Sudan: Usage and Exploration
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.
