Essential Oils Extracted from Different Species of the Lamiaceae Plant Family as Prospective Bioagents against Several Detrimental Pests
2020
On the basis of the side effects of detrimental synthetic chemicals, introducing healthy, available, and effective bioagents for pest management is critical. Due to this circumstance, several studies have been conducted that evaluate the pesticidal potency of plant-derived essential oils. This review presents the pesticidal efficiency of essential oils isolated from different genera of the Lamiaceae family including Agastache Gronovius, Hyptis Jacquin, Lavandula L., Lepechinia Willdenow, Mentha L., Melissa L., Ocimum L., Origanum L., Perilla L., Perovskia Kar., Phlomis L., Rosmarinus L., Salvia L., Satureja L., Teucrium L., Thymus L., Zataria Boissier, and Zhumeria Rech. Along with acute to…
Secondary metabolites from the aerial parts of Cytisus villosus Pourr
2017
Phytochemical investigation of the aerial parts of Cytisus villosus Pourr. resulted in the isolation and characterization of a new isoflavan, (3S, 4S)-2′,4′-dihydroxy-3′-methoxy-6,7-methylenedioxyisoflavan- 4-ol (1), and a new monoterpene, (4R,6S)-4-hydroxy-2,2,6-trimethyl-9-oxabicyclo [4.2.1] non-1(8)-en-7-one (2), together with four known flavonoids: geinstein (3), chrysin (4), chrysin -7-O-β-D-glucopyranoside (5) and 2″-O-α-L-rhamnosylorientin (6). The structures of the new compounds were elucidated on the basis of extensive spectroscopic analysis, including 1D, 2D NMR ((1)H, (13)C, COSY, TOCSY, HMBC and HSQC) and HRESIMS. The absolute configurations of 1 and 2 were established by the co…
