TL;DR: In this paper, the aerial parts of Stevia alpina afforded in addition to estafietin, dehydroleucodin, achillin, 2-oxo-8-deoxyligustrin and two known heliangolides two new guaianolides, the two epimeric 10(14)-epoxyestafietins, and the new heliangolate 3-acetylpulverolide.

G. P. Rao,Maneesha Singh,Priyanka Singh,S. P. Singh,César A.N. Catalán,I. P. S. Kapoor,O. P. Singh,Gurdip Singh +7 more
TL;DR: The leaf volatile oil of Lippia alba (Mill) has been analyzed by GC and GC-MS as discussed by the authors, and the major constituent is geranial (15.57%), followed by a unresolvable mixture of myrthenol and myrptonal (9.89%), neral (neral), geraniol (7.36%), 2,6-octadien-1-ol, 3,7-dimethyl acetate (6.87%), 1-octene-3-ol (4.60%), caryophy

Chemical composition and antifungal activity of essential oils from medicinal plants of Kazakhstan
Diego A. Sampietro,Analia de Los Angeles Gómez,Cristina M Jimenez,Emilio Fernando Lizarraga,Zharkyn A. Ibatayev,Yerlan Suleimen,César A.N. Catalán +6 more
TL;DR: The composition of essential oils from leaves of Kazakhstan medicinal plants was analysed by GC-MS and associated the antifungal activity with the presence of borneol, camphor, camphene, 1,8-cineole,α- and β-thujone, and of the oxygenated monoterpenes.

A structural and vibrational study of dehydrofukinone combining FTIR, FTRaman, UV–visible and NMR spectroscopies with DFT calculations
Emilio Fernando Lizarraga,Elida Romano,Ana Beatriz Raschi,Patricio Leyton,Carolina Paipa,César A.N. Catalán,Silvia Antonia Brandán +6 more
TL;DR: In this article, the vibrational and electronic properties of 4β,5β-eremophil-7(11)9-dien-8-one, also known as dehydrofukinone (DHF), have been investigated by using experimental FT-IR, FT-Raman, NMR and UV spectra techniques and density functional theory (DFT) employing B3LYP exchange correlation with the 6-31G* and 6-311++G** basis sets.

Three new diterpenoids based on the novel sarcopetalane skeleton from Croton sarcopetalus.
C. S. de Heluani,César A.N. Catalán,Luis R. Hernández,Eleuterio Burgueño-Tapia,Pedro Joseph-Nathan +4 more
TL;DR: The roots of Croton sarcopetalus afforded three new diterpenoids (2-4) with a novel carbon skeleton that seems to be derived biosynthetically from a pimarane precursor.
