Similitude Pattern and Botanical Origin of the Chilean Propolis: [with 2 figures & 4 tables] Phyton
Montenegro,G; Mujica,AM; Peña,RC; Gómez,M; Serey,I; Timmermann,BN.
Correspondence analysis allows identifying various kinds of propolis due to botanical source. The first site, Colliguay is identified by a higher content of pollen of Escallonia pulverulenta, and Nothofagus dombeyi. Two other very close sites are La Vacada and Quilaco, where pollen of Mentha pulegium, besides Echium, Cichorium, and Luma are frequently identified. Other groups including various contents of pollen of Eucalyptus, Salix or Prunus and other native resources such as Peumus, Cryptocarya and Quillaja are not well defined.

Analysis of volatile compounds in three unifloral native Chilean honeys Phyton
Montenegro,G; Gómez,M; Casaubon,G; Belancic,A; Mujica,AM; Peña,RC.
Three unifloral honeys were identified by the pronounced presence of specific compounds by means of sensorial analysis and SPME-GC-MS. Smoky and resinous (‘propolis') odors characterized unifloral "quillay" (Quillaja saponaria) honey. "Corontillo" (Escallonia pulverulenta) honey was characterized by caramel and vanillin aromas, and "ulmo" (Eucryphia cordifolia) honey by having an anise scent with a floral jasmine note. Safranal was a useful marker for "corontillo" honey. Isophorone and cetoisophorone were the distinctive compounds of unifloral "ulmo" honey. In "quillay" honeys, megastigmatrienone, 2-p-hydroxyphenylalcohol and minor quantities of β-pinene and linalool oxide were correlated with their sensory properties such as resinous.
Tipo: Info:eu-repo/semantics/article Palavras-chave: Ulmo honey; Escallonia or "corontillo" honey; Quillaja honey; SPME-GC-MS analysis.

Actividad antibacteriana y antifúngica de mieles monoflorales de Quillaja saponaria, especie endémica de Chile Phyton
Montenegro,G; Salas,F; Peña,RC; Pizarro,R.
En mieles monoflorales de la especie chilena Quillaja saponaria se detectaron los compuestos fenólicos: ácido cumárico y ácido salicílico, la flavona naringenina y el flavonol kaempferol, utilizando cromatografía líquida de alta resolución. Estos extractos mostraron actividad antibacteriana contra Pseudomonas aureginosa, Escherichia coli, Staphylococcus typhi, S. aureus, Streptococcus pneumoniae tipo β, y Vibrio cholerae, y actividad antifúngica contra la levadura Candida albicans. En el extracto etanólico, adicionalmente, se identificaron algunos compuestos del aroma y de descomposición.
Tipo: Info:eu-repo/semantics/article Palavras-chave: Miel; MIC; Quillaja saponaria; Manuka; Flavonas; Ácidos fenólicos; Compuestos fenólicos.
