High Add Valued Application of Turpentine in Crop Production through Structural Modification and QSAR Analysis

Abstract

Turpentine is a volatile component of resin, which is an abundant forest resource in Southern China. As one of the most important components, the integrated application of β-pinene has been studied. The broad-spectrum evaluation of β-pinene and its analogues has, therefore, been necessary. In an attempt to expand the scope of agro-activity trials, the preparation and the evaluation of the herbicidal activity of a series of β-pinene analogues against three agricultural herbs were carried out. In accordance with the overall herbicidal activity, it is noteworthy that compounds 6k, 6l, and 6m demonstrated extreme activity with IC50 values of 0.065, 0.065, and 0.052 mol active ingredients/hectare against E. crus-galli. The preliminary structure–activity relationship (SAR) was analyzed and the compounds with the appropriate volatility and substituent type that had beneficial herbicidal activity were analyzed. Simultaneously, the quantitative structure–activity relationship (QSAR) model was built and the most important structural features were indicated, which was, to a certain extent, in line with the SAR study. The study aimed to study the application of the forest resource turpentine in agriculture as a potential and alternative approach for comprehensive utilization.

Derivatization of Natural Compound β-Pinene Enhances Its In Vitro Antifungal Activity against Plant Pathogens

“…Li et al reported that a series of decanoic acid thiourea derivatives have good antifungal activity against various plant pathogenic fungi [14]. Gao et al reported that a series of terpene-based acyl-thiourea derivatives showed moderate to excellent antifungal activities against several fungi [16,17].…”

“…The compound β-pinene is a natural compound with antimicrobial activity [8,9,10] which can be used to participate in numerous chemical reactions. Masses of β-pinene derivatives can be synthesized by chemical modification, and some of these derivatives have been proved to have better antifungal activity [11,12,13,14,15,16,17]. For example, Li et al [14] synthesized three series of β-pinene-based derivatives, and tested their fungicidal activity against three agricultural fungi.…”

Propiedades volumétricas y de transporte para las mezclas binarias de β-pineno + n-dodecano

“…El β-pineno es un monoterpeno bicíclico obtenido principalmente de la resina de los pinos (Gao et al, 2018); en estudios recientes, se ha propuesto su uso como biocombustible o bioaditivo para las gasolinas, el diésel y la turbosina (Anand, Saravanan, & Srinivasan, 2010;Donoso, García, Ballesteros, Lapuerta, & Canoira, 2021;Hudaya, Widjaja, Rionardi, & Soerawidjaja, 2016;Jung et al, 2016;Knuuttila, 2013). Por otro lado, el ndodecano es un alcano de cadena lineal compuesto por 12 átomos de carbono y 25 átomos de hidrógeno, utilizado como molécula para modelar el comportamiento de las turbosinas debido a sus propiedades termodinámicas (Honnet, Seshadri, Niemann, & Peters, 2009).…”

β-Pinene Derived Products With Enhanced In Vitro Antimicrobial Activity

“…9 -13 A large number of β-pinene derivatives can be synthesized by chemical modification, and some of these derivatives have been proved to have increased antibacterial activities. 14 -19 For example, Gavrilov et al 20 synthesized 3 series of β-pinene-based derivatives, and the reaction mixes of the sulfoxides had high activity against Penicillium tardum . Recently, cationic antimicrobial agents have been shown to be very effective bacteriostatic agents and are used in many applications, such as pesticides, hospital protective clothing, medical implants, wound dressings, and food packaging materials.…”
