In vitro antiproliferative and antifungal activity of essential oils from Erigeron acris L. and Erigeron annuus (L.) Pers.
Antiproliferative and antifungal activities of essential oils from Erigeron acris root and herb and from Erigeron annuus herb were investigated. The cell viability assay was performed in cultured fibroblasts, cancer cell lines (MCF-7 and MDA-MBA-231), and endometrial adenocarcinoma (Ishikawa) cells as well as colon adenocarcinoma (DLD-1) cells using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetr...
متن کاملChemical composition of the essential oils from the roots of Erigeron acris L. and Erigeron annuus (L.) Pers.
The chemical compositions of essential oils from the roots of Erigeron acris and Erigeron annuus were studied. The essential oils were obtained by hydrodistillation in 1.0% and 0.05% yield, respectively, and analyzed by GC, GC-MS. Fifty four and forty seven constituents were identified. Predominant constituents of both oils were poly-acetylene esters: (Z,Z)-matricaria ester (49.4% and 45.9%, re...
متن کاملTwo independent loci control agamospermy (Apomixis) in the triploid flowering plant Erigeron annuus.
Asexual seed production (agamospermy) via gametophytic apomixis in flowering plants typically involves the formation of an unreduced megagametophyte (via apospory or diplospory) and the parthenogenetic development of the unreduced egg cell into an embryo. Agamospermy is almost exclusively restricted to polyploids. In this study, the genetic basis of agamospermy was investigated in a segregating...
متن کاملA Note On Logical PERs and ReducibilityLogical Relations
We prove a general theorem for establishing properties expressed by binary relations on typed ((rst-order)-terms, using a variant of the reducibility method and logical PERs. As an application, we prove simultaneously that-reduction in the simply-typed-calculus is strongly normalizing, and that the Church-Rosser property holds (and similarly for-reduction).
متن کاملNeuroprotective and anti-oxidant effects of caffeic acid isolated from Erigeron annuus leaf
BACKGROUND Since oxidative stress has been implicated in a neurodegenerative disease such as Alzheimer's disease (AD), natural antioxidants are promising candidates of chemopreventive agents. This study examines antioxidant and neuronal cell protective effects of various fractions of the methanolic extract of Erigeron annuus leaf and identifies active compounds of the extract. METHODS Antioxi...
