TL;DR: In this article, 14 daucane esters together with a known propiophenone 3,4-methylenedioxy-5-hydroxy-propiophenone were isolated from Ferula communis subsp. communis.

TL;DR: Six known terpenoids were isolated from the leaves of Salvia palaestina and were identified by spectral data, and sclareol showed high activity against Staphylococcus aureus, S. epidermis, Escherichia coli, Proteus vulgaris and Pseudomonas aeruginosa.

TL;DR: In this paper, a 4-dehydrochromolaena glaberrima was investigated and the structure of the new compound was elucidated by spectroscopic methods, which is the first known 4-Dehydro chromolaenide.

TL;DR: The structure of the flavone brickellin has been revised and confirmed by synthesis and the correct structure is 5,2-dihydroxy-3,6,7,4′,5′-pentamethoxyflavone.

TL;DR: In this paper, three sesquiterpene lactones, 2′, 3′-dihydroniveusin-A and 3-acetylchamissonin, were isolated from the dichloromethane extract of leaves of Viguiera deltoidea.

TL;DR: The structures of the new compounds were 3,5,7,3,3′,4′-pentahydroxy-6,8-dimethoxyflavone, 5,7-3′-trihydroxy-3,6, 8, 4, 4, 5, 7, 3′, 4′, 5.5′ pentamethoxyFLavone 3′-Oglucoside as mentioned in this paper.

TL;DR: By using HPLC, a new melampolide, a known heliangolide and three known germacrolides were isolated as minor constituents from a north central Texas population of Helianthus maximiliani.

TL;DR: The results of this study support previous proposals that H. divaricatus, H. resinosus and H. salicifolius are closely related, and that H Mollis may be a progenitor of the hexaploid H. mollis.

TL;DR: Six germacranolides, tirotundin, tagitinin A, orizabin, 8β,14-dihydroxycostunolide and its 14-isobutyrate, and 4β,5- dihydrotagit inin C, were isolated from aboveground parts of Helianthus niveus subsp.

TL;DR: In this paper, four 6-methoxylated flavonols, including quercetagetin derivative and its 3-potassium sulphate salt, were isolated from the aerial parts of Decachaeta haenkeana.

TL;DR: A new geranylgeraniol type diterpene, named viguieric acid, was isolated from the dichloromethane extracts of V. deltoidea as mentioned in this paper.

TL;DR: A new highly unstable acetoxy-furanoeudesmane was obtained from the fruits of Smyrnium olusatrum, which obviously is the precursor of the two acet Oxy-eudesmanolides.

TL;DR: In this article, a sesquiterpene dilactone, maximileolide, was isolated from Helianthus maximiliani and its structure determined by high field NMR spectroscopy with the aid of difference spectroscopic techniques.

TL;DR: Two new diterpenes, 3α, 18-dihydroxy-13-furyl-ent -labda-8(17)-ene and 3α-hydroxy-18-angeloyloxy- 13-fural- ent -labelda- 8(17) were isolated from the leaves of Gutierrezia grandis as discussed by the authors, their structures were determined by mass spectral, IR, 1 H NMR and 13 C NMR data was well as chemical evidence.

TL;DR: Two new elemanolides and the known germacrolide 11,13-dehydroeriolin from Schkuhria anthemoidea var.

TL;DR: Investigation of the minor terpenoids in Helianthus niveus subsp.
