The root of Polygala tenuifolia Willdenow has been used for the treatment of insomnia, depression, and amnesia. However, the toxicological properties of the herb have been overlooked, because it has been used for a long time for various purposes. In this study, we evaluated the preclinical safety of the root extract in rats and beagle dogs. First, the acute oral toxicity was tested in both rats...

Drought tolerance was evaluated in twelve cultivars of three ornamental Tagetes species (T. patula, T. tenuifolia and T. erecta). A stress treatment was performed by completely stopping watering of plants maintained in controlled greenhouse conditions. After three weeks, several plant growth parameters (stem length (SL), fresh weight (FW) and water content (WC)), photosynthetic pigments (chloro...

Global warming has created opportunities and challenges for the survival and development of species. Determining how climate change may impact multiple ecosystem levels and lead to various species adaptations is necessary for both biodiversity conservation and sustainable biological resource utilization. In this study, we employed Maxent to predict changes in the habitat range and altitude of P...

Symbioses between plants and nitrogen (N) fixing bacteria are ecologically and economically important interactions with complex evolution and ecology. Theoretical and experimental studies suggest that host specificity and environmental variation are important determinants of both evolutionary and ecological patterns in such interactions, but detailed descriptions of these parameters in natural ...

achillea millefolium belong to the asteraceae family and from genus achillea. in this study essential oils were extracted from all aerial parts via hydro distillation (hd) method by clevenger set . by using of gas chromatography/mass spectrometry ( gc-ms) technique the chemicals component essential oil were identified. about 41 components with were identified which encompassed 97.66 percent of ...

The phytochemical composition of plants is very diverse and includes many biologically active substances, their combination determines the pharmacological activity. This article examines underground part Paeonia tenuifolia L. leaves Petrocoma hoefftiana (Fisch.) Rupr. It was found that studied objects contain glycyrrhizic acid, peucedanin, flavonoids, phloroglucides, tannins, ascorbic acid. can...

Plantibacter flavus isolate 251 is a bacterial endophyte isolated from an Achillea millefolium plant growing in a natural oil seep soil located in Oil Springs, Ontario, Canada. We present here a draft genome sequence of an infrequently reported genus Plantibacter, highlighting an endophytic lifestyle and biotechnological potential.

Occupational asthma is induced by many agents, including herbal materials, that are exposed in working places. Although there are a few case reports for occupational allergy induced by herbal materials, there is none for that induced by Wonji (Polygala tenuifolia). This study was conducted to evaluate clinical characteristics and immunologic mechanism of Wonji-induced asthma in a exposed-worker...
