Chemical composition and allelopathic, antibacterial, antifungal and in vitro acetylcholinesterase inhibitory activities of yarrow ( Achillea millefolium L.) native to India

Screening of yarrow (Achillea millefolium Agg.) populations in Serbia for yield components and essential oil composition

“…Majority of oil yield (59% of populations) have been observed in amounts more than 0.5%. These data are accordance than previously reported, where yarrow oil yield ranged from 0.11 to 1.03% (Verma et al, 2017;Spinarova and Petrikova, 2003;Raal et al, 2012;Ghasemi Pirbalouti, 2017). Dachler and Pelzmann (1999) reported yarrow yields up to 0.5%.…”

“…The high amount of 1,8-cineole (34.2%) has been reported A. eriophora (Weyerstahl et al, 1997). The high amount of sabinene, as we found in our populations 36, 38 and 39 (19.3-35.7%), has been also previously reported (Verma et al, 2017;Nadim et al, 2011;Conti et al, 2010;Boskovic et al, 2005). Serbian populations were lower in sabinene content, while introduced populations (Hohenheimer Gärten and commercial variety ProA) had very high content.…”

Chemical Composition and Allelopathic, Antibacterial, Antifungal, and Antiacetylcholinesterase Activity of Fish‐mint (Houttuynia cordataThunb.) from India

“…cordata possessed more phytotoxic activity than crude shoots powder. The phytotoxicity of the essential oils has been reported by several studies . It depends on the chemical composition, and in particular on the content of ketones, which are reported as a powerful germination inhibitor .…”

Insecticidal potential of some plant extracts in nano and normal form on immatures stages of red palm weevil Rhynchophorus ferrugineus

“…Eucalyptus had an insecticidal against activity against wide range of insect pests, peach fruit fly (Ali, 2018), Tribolium castaneum (Herbst) (Ahmad et al, 2019) and RPW (Ali et al). The botanical activity of eucalyptus oils return to its major contents like 1,8-cineole, limonene, linalool, a-pinene, and a-terpineol, (Batish et al, 2008;Noumi et al, 2011), 1,8-Cineole, leading to damaged structural stability of the cell, leading successively to increased permeability (Verma et al, 2017). These components acted on AChE and octopamine receptors, (Castillo-Morales et al, 2019),and 1.8-cineol It can act as an antagonist to histamine receptors, (Beer et al, 2017).…”
