Caulopterae, have been analyzed by GC and GC\/MS. Despite the morphological similarity among these species, differences in composition of their essential oil obtained by hydrodistillation and hexane extract could be observed. Special attention was given to Baccharis trimera and B. crispa since their differentiation during early stages is not possible due to the absence of synflorescences. Carquejyl acetate is suggested as a marker for Baccharis trimera, and a fast method of detection of this compound is given. \u00a9 Springer-Verlag 2005."},{"@type":"Nota de alcance","@lang":"es","@value":"\u00daLTIMOS AVANCES EN LA QU\u00cdMICA Y ACTIVIDADES BACTERIOL\u00d3GICAS EN LAS PLANTAS MEDICINALES\n1) The objective of this work was to verify the influence of different drying processes on the levels of quercetin of the aerial parts of Baccharis articulata (Lam.) Pers., Asteraceae, as well as the evaluation of the in vitro antioxidant activity of these exts.\u00a0 We demonstrated that the highest concn. of this flavonoid was detected in oven-dried samples, although there no significant difference in their pharmacol. activity of all analyzed samples could be shown. \n\n2) The essential oil obtained from aerial parts of Baccharis articulata (Lam.) Pers. from Rio Grande do Sul, Southern Brazil, was analyzed by GC, GC\/MS, and chiral phase gas chromatog. (CPGC).\u00a0 Twenty-nine compds. representing ca 86.1 % of the oil were identified.\u00a0 The main compds. in the oil were beta-pinene (39.0%), cis-beta-guaiene (9.8%), gamma-muurolene (5.8%), limonene (4.8%), alpha-pinene (4.5%), alpha-gurjunene (4.4%) and spathulenol (4.2%).\u00a0 The antimicrobial activity of the oil was evaluated against seven microorganisms using the broth microdilution method.\u00a0 The oil displayed antimicrobial activity against Gram-pos. and Gram-neg. microorganisms (MIC=2.5 mg\/mL).\u00a0\n3) Baccharis articulata is traditionally used as diuretic and digestive in local folk medicine of south of Brazil, Uruguay and Argentina.\u00a0 The antioxidant activity of crude ethanol and aq. exts., together with dichloromethane, Et acetate and n-butanol fractions obtained from aq. ext. of B. articulata was detd. using TRAP and TBARS assays.\u00a0 The n-butanol fraction was found to be the most active and its major compd. (BaII) was isolated, identified and assayed.\u00a0 The structure of the phenolic compd. BaII was established by means of spectroscopic and chem. methods as 4'-O-beta-D-glucopyranosyl-3', 5'-dimethoxybenzylcaffeate.\u00a0 This previously unreported metabolite presented similar antioxidant capacity when compared to Trolox.\n\n"},{"@type":"Nota de alcance","@lang":"es","@value":"Patente extra\u00edda del Chemical Abstracts\nCosmetic and topical compositions containing singlet oxygen-scavenging, hyaluronidase-inhibiting, and collagen synthesis-enhancing plants.
