HPTLC and GC-MS for separation and identification of eugenol in plants
2007
Samples of clove, nutmeg, and cinnamon have been extracted by maceration with ethanol for 24 h and with aqueous ethanol 48 h. Rhizomes of herb bennet ( Geum urbanum ) and calamus ( Aconum calamus ) and roots of valerian ( Valeriana officinalis ) have been subjected to aqueous hydrolysis then extraction with dichloromethane. The active principles from the samples were separated on silica gel HPTLC plates, with pure (standard) and dental (pharmaceutical) eugenol, using n -heptane-ethyl acetate 60+40 ( v / v ) as mobile phase. After development the components were visualized in UV light at λ = 254 nm. The presence of eugenol was confirmed by GC-MS.
Teratogenicity and Developmental Toxicity of Herbal Products
2017
Developmental toxicology and research in teratogenicity focus on xenobiotic substances that damage embryos and fetuses and lead to death, growth retardation, and/or malformation of offspring. While considerable information has been acquired about synthetic drugs and environmental xenobiotics, much less is known about the teratogenicity of herbal products. In this chapter we report on some major topics of developmental toxicity and teratogenicity, and discuss the safety of a few selected medicinal herbs in this context, i.e., Artemisia annua L., Caulophyllum thalictroides (L.) Michx., Echinacea spec,. Glycyrrhiza spec., herbs derived from Chinese medicine, Hypericum perforatum L., Panax gins…

The process entailed a search of PubMed, Scopus, and the Cochrane Library databases from 2010 to 2020. The search terms included “sleep d…
Studies concerning the production of volatile oil, rhizomes and roots, to different genotypes of Valeriana officinalis L.
2010
Valeriana officinalis L. is considered to pertain to European species, with great ecologic plasticity, which allows its adaptation to climate conditions characteristics to plain areas and also to mountain areas up to an altitude of 2400 meters. The species is a well-known curative plant, with a long history and multiple uses. Essential oils deriving from this species revealed the interest of researchers in food industry, cosmetics and officinal industry, furthermore being used as additives too.The raw material from which essential oils are being extracted is represented mainly by rhizomes and roots. This study has the purpose to emphasize the differences of essential oils production registe…
