Three new acyclic monoterpenoids named (2E)-3,7-dimethylocta-2,6-dienoate-6-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (1), (3Z,6E)-3,7-dimethyl-3,6-octadiene-1,2,8-triol (2) and (6E)-7-methyl-3-methylene-6-octene-1,2,8-triol (3) were isolated from Acanthopanax sessiliflorus fruits, along with three known monoterpenoid compounds. The structures of the new compounds were determined by mean...

Plants make specialized bioactive metabolites to defend themselves against attackers. The conserved control mechanisms are based on transcriptional activation of the respective plant species-specific biosynthetic pathways by the phytohormone jasmonate. Knowledge of the transcription factors involved, particularly in terpenoid biosynthesis, remains fragmentary. By transcriptome analysis and func...

Concentration and composition of monoterpenoids in plant tissue affects a variety of environmental and ecological issues such as plant defenses, plant classification, and phytotoxicity. Developing the techniques for extracting and estimating the concentration and composition of monoterpenoids must be speciesspecific because monoterpenoid storage location varies between species.

A new cycloartane-type saponin with unusual hydroxylation at C-17 and a unique side chain, 9 (R), 19, 22 (S), 24 (R) bicyclolanost-3β, 12α, 16β, 17α tetrol-25-one 3-O-β-d-glucopyranosyl-(1→2)-β-d-glucopyranoside (1) and two new monoterpenoid glucoindole alkaloids, 10-methoxy pumiloside (2) and the previously chemically synthesized, 10-methoxy strictosidine (3) along with other five known compou...

From cell suspension cultures of Ochrosia elliptica Labill. eight different monoterpenoid indole alkaloids were isolated and comprised three alkaloid classes viz. Corynanthe/Heteroyohimbine (tetrahydroalstonine, cathenamine, pleiocarpamine and two methoxylated heteroyohimbines), Strychnos (norfluorocurarine), Apparicine (apparicine and epchrosine). All these compounds except the Strychnos alkal...

Two new labdane-type diterpenoids vitetrifolin H (1) and vitetrifolin I (2), and one new monoterpenoid vitexoid (3), were isolated from the fruits of Vitex trifolia L., together with seven known diterpenoids. Structures of all compounds were elucidated by extensive spectroscopic methods. All these compounds exhibited inhibition of Hela cell proliferation, with IC50 values in the range of 4-28 m...
