TL;DR: Three new substituted bibenzyls (1,2-diarylethanes) aloifol I and aloIFol II and a new substituted 9,10-dihydrophenanthrene, 6-O-methylcoelonin in addition to batatasin III, coel onin and gigantol have been isolated and characterized.

TL;DR: Silica gel chromatography of the fraction from Arnebia nobilis possessing antibiotic and anticancer activities has yielded three new naphthaquinones, 5,8-dihydroxy-2-(1′-β,β-dimethylacryloxy-4′-methylpentyl)-1,4-naphtha-quinone as mentioned in this paper.

TL;DR: A further re-examination of the seeds of Nyctanthes arbor-tristis has led to the isolation and identification of two new minor iridoid glucosides, arbortristoside D and E, together with the previously reported arbortside B.

TL;DR: A new iridoid glycoside along with the known compounds, nyctanthic acid, oleanolic acid, friedelin, β-sitosterol glucoside, 6β-hydroxyloganin and arbortristoside A have been isolated from Nyctanthes arborristis and characterized by spectral and chemical means as mentioned in this paper.
