TL;DR: Variations in essential-oil yield, composition and contents of leaf and root essential-oils of B. albiflora collected from four different climatic locations were compared and significant quantitative variations were noticed.
Abstract: The essential-oil yield and composition of the aerial parts of Boenninghausenia albiflora were analyzed and compared by capillary GC-FID and GC–MS at different stages of growth and on drying prior to distillation. The essential-oil content of the aerial parts was found to vary from 0.15–0.20 % at different phenophases. Essential-oils were mainly composed of sesquiterpenoids (44.62–52.11 %) and monoterpenoids (25.73–45.95 %). Sesquiterpenoids (44.62–52.11 %) portion of essential-oils was represented by germacrene D (4.18–18.21 %), epi-α-cadinol (0.14–16.25 %), β-caryophyllene (4.62–13.14 %), globulol (0.26–9.22 %), and β-copaene-4α-ol (0.14–7.52 %); while β-myrcene (2.09–26.11 %) and β-pinene (8.36–13.77 %) were the major monoterpenoids. Variations in essential-oil yield (0.15–0.20 %), and contents of monoterpene hydrocarbons (19.38–42.59 %), sesquiterpene hydrocarbons (15.38–36.92 %) and oxygenated sesquiterpenes (9.97–36.73 %) due to different growth stages (vegetative, flowering and seed setting stages) of B. albiflora were noticed. On drying viz. sun and shade drying of the aerial parts of B. albiflora have no drastic influence on essential-ol quality; but significant quantitative variations were noticed. Further, variations in essential-oil composition of leaf and root essential-oils of B. albiflora collected from four different climatic locations were also compared.

TL;DR: The results demostrated that Boenninghausenia sessilicarpa, Laggera pterodont,Humulus scanden and Rabdosia of ethanol extracts possessed significantly ovicidal activity four extracts, of which LC50 was 1.7032 mg·mL-1.
Abstract: The bioactivities of ethanol extracts from twenty plants against Panonychus citri were measured in the laboratory with the glass plate dipping to find the strongest acaricidal plant.The results demostrated that Boenninghausenia sessilicarpa,Laggera pterodont,Humulus scanden and Rabdosia of ethanol extracts,of which LC50 were 0.9241,0.9827,0.9905 and 1.0196 mg·mL-1,respectively.The extracts of B.sessilicarpa possessed significantly ovicidal activity four extracts,of which LC50 was 1.7032 mg·mL-1.
