“…Among the fourteen naphthoquinones and their analogs tested, juglone and plumbagin possessed the strongest acaricidal activities against P. cuniculi with LC 50 values less than 25 ppm in vitro . These compounds presented better acaricidal activity than most plant-based acaricides 13 , 23 – 26 . In vivo , juglone and plumbagin at 50 ppm presented similar therapeutic effects when administered to rabbits infested with P. cuniculi .…”

“…Many plants, including Azadirachta indica, Adonis coerulea , Eugenia caryophyllata , and Eupatorium adenophorum , have a high toxicity to P. cuniculi and have shown significant clinical efficacy when used in the clinic to control animal acariasis 19 – 22 ; the advantages of this approach include high efficiency, lower resistance, and decreased pollution. Furthermore, several active compounds have been isolated, such as eugenol, δ-cadinene, carvacrol, octadecanoic acid-tetrahydrofuran- 3,4-diylester, and 9-oxo-10,11-dehydroageraphorone, among others, which were used as lead compounds to develop potential acaricides 13 , 23 – 26 . However, the acaricidal activities of naphthoquinones against P. cuniculi have not been reported, and their possible mechanisms of action are currently unknown.…”

As important secondary plant metabolites, naphthoquinones exhibit a wide range of biological activities. However, their potential as sustainable alternatives to synthetic acaricides has not been studied. This study for the first time investigates the acaricidal activity of naphthoquinones against Psoroptes cuniculi in vitro. Furthermore, the in vivo activity, the skin irritation effects, the cytotoxicity and the inhibitory activities against mite acetylcholinesterase (AChE) and glutathione S-transferase (GST) of the two compounds that displayed the best insecticidal activity in vitro were evaluated. Among fourteen naphthoquinones and their analogs, juglone and plumbagin were observed to possess the strongest acaricidal activities against P. cuniculi with LC50 values of 20.53 ppm and 17.96 ppm, respectively, at 24 h. After three treatments, these two chemicals completely cured naturally infested rabbits in vivo within 15 days, and no skin irritation was found in any of the treated rabbits. Compared to plumbagin, juglone presented no or weak cytotoxicity against HL-7702 cells. Moreover, these two chemicals significantly inhibited AChE and GST activity. These results indicate that juglone has promising toxicity against P. cuniculi, is safe for both humans and animals at certain doses, and could be used as a potential alternative bio-acaricide for controlling the development of psoroptic mange in agricultural applications.

“…Among its described utilities are that it is an antidepressive [76], is neuroprotective [77], and can prevent Alzheimerʼs disease [78]. Regarding the Aniba canelilla a (leaf) (01) 1-Nitro-2-phenylethane (88.9 %) (02) β-Caryophyllene Toxic against brine shrimp [14] Aniba rosaeodora b substance δ-cadinene, its reported activities include antitumoral [79], antimicrobial [80], and acaricide [81]. Sesquiterpene δ-cadinene has a cadinan skeleton originating from the cyclization of nerolidine pyrophosphate, which has farnesyl pyrophosphate as a precursor [82], and α-pinene is a bicyclic monoterpene with many documented activities due to its anti-inflammatory [83,84] and antiulcerogenic [85] properties.…”

Chemical Composition and Biological Activities of Essential Oils in the Family Lauraceae: A Systematic Review of the Literature

et al. 2019

The Lauraceae family is predominantly found in Asia and in the rainforests of the Americas, and consists mostly of aromatic trees. Being an essential oil producer, this family is used in the food, pharmaceutical, and cosmetic industries. This work presents a systematic review of the chemical composition and bioactivity of the essential oils from the Lauraceae family. Medline, Scielo, Web of Science, Lilacs, and Scopus were employed to identify articles published between 2000 and 2018, using “Lauraceae”, “essential oil”, and “biological activity” as key words. From 177 studies identified, 53 met the inclusion criteria. These studies indicated a predominance of the compounds β-caryophyllene and 1,8-cineole in Lauraceae species, and highlighted the antioxidant, antifungal, antibacterial, and anti-inflammatory activities. Essential oils extracted from this family thus have high potential for pharmacological applications.

“…Evidence for lime tolerance can also be found in species that co-occur in similar habitats. An example is R. nivale , a perennial evergreen undershrub with a height of 30–120 cm, distributed in the northeastern and southeastern areas of the Tibet Autonomous Region of China, Nepal, India, Bhutan, and Sikkim ( Guo et al, 2017 ). This species co-occurred with R. primuliflorum as the representative alpine species in the snowy mountains in the northwest of Yunnan ( Xu et al, 1996 ), which grows in limestone crevices shared with Paraquilegia anemonoides , another species associated uniquely with limestone.…”

Prediction of Lime Tolerance in Rhododendron Based on Herbarium Specimen and Geochemical Data

et al. 2018

Rhododendrons are typically known to be calcifuges that cannot grow well in lime soils. Data on lime tolerance of different taxa in Rhododendron are scarce. Habitats of naturally distributed specimens of genus Rhododendron were compiled as Chinese text-based locations from the Chinese Virtual Herbarium. The locations were then geocoded into latitude/longitude pairs and subsequently connected to soil characteristics including pH and CaCO3 from the Harmonized World Soil Database (HWSD). Using the upper quartile values of pH > 7.2 and CaCO3 > 2% weight in topsoil as threshold, we predicted the lime tolerant taxa. A dataset of 31,146 Rhododendron specimens including the information on taxonomy, GPS locations and soil parameters for both top- and subsoil was built. The majority of the specimens were distributed in soils with moderately acidic pH and without presence of CaCO3. 76 taxa with potential lime tolerance were predicted out of 525 taxa. The large scale data analysis based on combined data of geocoded herbarium specimens and HWSD allows identification of valuable Rhododendron species, subspecies or botanical varieties with potential tolerance to lime soils with higher pH. The predicted tolerant taxa are valuable resources for an in-depth evaluation of lime tolerance or for further use in horticulture and breeding.
