TL;DR: The tree fern Cyathea gigantea yielded hentriacontane, β-sitostenone, β -sitostanone, diploterol, sitosterol, hopan-29-ol, and oleanolic acid from the hexane soluble fraction of the plant.
Abstract: The tree fern Cyathea gigantea yielded hentriacontane, β-sitostenone, β-sitostanone, diploterol, sitosterol, hopan-29-ol, and oleanolic acid from the hexane soluble fraction of the plant. CDRI Communication No. 3961Compounds III and V belonging to hopane series of triterpenes are generally found in lower plants. Compound V is reported for the first time from family Cyatheaceae.

TL;DR: It appears that synergism plays a role in antimicrobial activity of plant extracts and that the hope of isolating a single compound that can be used as a new agent to address antibiotic resistance has been frustrated.
201 citations
TL;DR: The distribution and biosynthesis of iridoid glucosides in the Oleaceae is reviewed and five distinct biosynthetic pathways to iridoids have been identified in the family, deoxyloganic acid apparently being a common intermediate.

TL;DR: Two new phenanthrenes (4,9-dimethoxyphenanthrene-2,5-diol and 4,6-dimethyltoxymethylhexane-1,3,7-triol) and two new 9,10-dihydrophenanthreness (4methoxy-9, 10-dibenzyls and the triterpenoid friedelin were isolated and characterized from the hexane extract of the orchid Bulbophyllum vaginatum) were determined by spectroscopic analyses
