“…During growth and development, plants generate around 100,000 chemical products, of which, 1700 are volatile organic compounds (VOC) [2] presented in essential oils. These molecules are emitted by different plant organs including leaves, flowers, fruits, and roots [2,3]. Plant VOCs are chemically classified into different groups such as fatty acid derivatives, terpenes, indole, and molecules from other chemical families.…”

“…Plant VOCs are chemically classified into different groups such as fatty acid derivatives, terpenes, indole, and molecules from other chemical families. Biologically, volatile compounds are not only to protect themselves from herbivores and microbial pathogens, but they also release signals and messages to insects and neighbouring plants [3]. Due to having therapeutic benefits and high absorbability through the skin, VOCs and essential oils have been widely applied in different sectors including food, cosmetic, and medicinal production [4].…”

Phytochemical Analysis and Potential Biological Activities of Essential Oil from Rice Leaf

Although many investigations on phytochemicals in rice plant parts and root exudates have been conducted, information on the chemical profile of essential oil (EO) and potent biological activities has been limited. In this study, chemical compositions of rice leaf EO and in vitro biological activities were investigated. From 1.5 kg of fresh rice leaves, an amount of 20 mg EO was obtained by distillation and analyzed by gas chromatography-mass spectrometry (GC-MS), electrospray ionization (ESI), and atmospheric pressure chemical ionization (APCI) to reveal the presence of twelve volatile constituents, of which methyl ricinoleate (27.86%) was the principal compound, followed by palmitic acid (17.34%), and linolenic acid (11.16%), while 2-pentadecanone was the least (2.13%). Two phytoalexin momilactones A and B were first time identified in EO using ultra-performance liquid chromatography coupled with electrospray mass spectrometry (UPLC/ESI-MS) (9.80 and 4.93 ng/g fresh weight, respectively), which accounted for 7.35% and 3.70% of the EO, respectively. The assays of DPPH (IC50 = 73.1 µg/mL), ABTS (IC50 = 198.3 µg/mL), FRAP (IC50 = 700.8 µg/mL) and β-carotene oxidation (LPI = 79%) revealed that EO possessed an excellent antioxidant activity. The xanthine oxidase assay indicated that the anti-hyperuricemia potential was in a moderate level (IC50 = 526 µg/mL) as compared with the standard allopurinol. The EO exerted potent inhibition on growth of Raphanus sativus, Lactuca sativa, and two noxious weeds Echinochloa crus-galli, and Bidens pilosa, but in contrast, the growth of rice seedlings was promoted. Among the examined plants, the growth of the E. crus-galli root was the most inhibited, proposing that constituents found in EO may have potential for the control of the problematic paddy weed E. crus-galli. It was found that the EO of rice leaves contained rich phytochemicals, which were potent in antioxidants and gout treatment, as well as weed management. Findings of this study highlighted the potential value of rice leaves, which may provide extra benefits for rice farmers.

“…Upland cotton ( Gossypium hirsutum L. Malvaceae) is cultivated worldwide as a major source of natural fiber and suffers from high levels of herbivory from multiple insect pests (Hagenbucher et al, 2013). Increasing our understanding of the natural defense mechanisms of cotton could aid in the advancement of sustainable pest control strategies and the development of more resistant cultivars (Mitchell et al, 2016; Pickett and Khan, 2016; Turlings and Erb, 2018; Villamar-Torres et al, 2018). Cotton plants constitutively store volatile mono- and sesquiterpenes in specialized glands present in their leaf tissues (Elzen et al, 1985; Hagenbucher et al, 2013).…”

Upland cotton (Gossypium hirsutum) plants constitutively store volatile terpenes in their leaves, which are steadily emitted at low levels. Herbivory leads to a greater release of these stored volatiles. Additionally, damaged plants increase terpene accumulation and emit other terpenes and additional volatiles. This has been well characterised for cultivated cotton, but little is known about volatile emissions in wild cotton. We investigated how herbivory by the beet armyworm (Spodoptera exigua) affects both leaf-stored and emitted volatiles in wild cotton plants from populations found along the Yucatan coast and assessed different scales of intraspecific variation in induced volatiles. Furthermore, we examined how leaf-terpene chemotypes differ in volatile emissions from intact and damaged plants. Herbivory triggered changes in stored and emitted volatiles in a manner similar to what is known for cultivated cotton. However, we report for the first time the emission of volatile aldoximes by cotton plants, which were only detected in the headspace upon herbivory, and displayed interpopulation variation. Intraspecific variation was also observed in the induced emissions of nitriles and some terpenes. In addition, chemotypes differed in their induction of the (E)-beta-ocimene in leaves. Distinctions between terpene chemotypes were reflected in the emissions from both intact and damaged plants, suggesting differences in how dominant terpenes of each chemotype might affect airborne interactions. However, these variable terpenes showed weak inducibility, raising questions about their functions. This comprehensive insight into herbivore-induced volatiles in wild cotton may help in the development of future pest-management strategies for cotton crops.
