“…In the essential oil from the biotic-stressed, herbivore-damaged leaf, the presence of only two compounds has been identified that had not been found in the essential oil samples from undamaged or mechanically-damaged leaves: β-Gurjunene (2.1%) and spirolepechinene (2.5%), associated with the inducible defense of I. alba in response to damage by the grasshopper E. trilineata. Essential oil extracted from the Dipsacus asper roots exhibited larvicidal activity against Aedes aegypti and Culex pipiens; β-Gurjunene has been identified as one of the major compounds in the oil [24] . The spirolepechinene is a spirosesquiterpene found in Lepechinia bullata and of a unique structure [25] .…”

There is no doubt that the chemical composition of plants, including norvolatile and volatile compounds, is widely affected by abiotic and biotic stress. Plants are able to biosynthesize a variety of secondary metabolites against actions of natural enemies, such as herbivores, fungus, virus and bacteria. The present study revealed that the chemical compositions of leaf essential oils from Ipomoea alba underwent quantitative and qualitative alterations both when infested with the grasshopper Elaeochlora trilineata and mechanically damaged. Grasshopper attack and mechanical wounding induced the biosynthesis of nine volatile compounds in leaves of I. alba: cumene, α-ylangene, β-panasinsene, β-gurjunene aromadendrene, β-funebrene, spirolepechinene, cubenol and sclareolide. The amount of germacrene D (33.2% to 20.4%) decreased when the leaves were mechanically damaged; but when the leaves were attacked by a grasshopper, the germacrene D increased from 33.2% to 39.4%. The results showed that I. alba leaves clearly responded to abiotic and biotic stress and contribute to an understanding of plant responses to stress conditions.

“…However, due to the different growth environments, the accumulated active components and the quality of D. asperoides have shown marked differences in different cultivation bases [2][3][4]. At present, research on D. asperoides has primarily focused on chemical composition [5], cultivation [6], pharmacology [7], and transcriptomics [1]. Triterpenoid saponins, such as dipsacus saponin VI, macranthoidin A and HN saponin F, are the principal active ingredients of D. asperoides [8].…”

Dipsacus asperoides is a kind of Chinese herbal medicine with beneficial health properties. To date, the quality of D. asperoides from different habitats has shown significant differences. However, the molecular differences in D. asperoides from different habitats are still unknown. The aim of this study was to investigate the differences in protein levels of D. asperoides from different habitats. Isobaric tags for relative and absolute quantification (iTRAQ) and 2DLC/MS/MS were used to detect statistically significant changes in D. asperoides from different habitats. Through proteomic analysis, a total of 2149 proteins were identified, of which 42 important differentially expressed proteins were screened. Through in-depth analysis of differential proteins, the protein metabolism energy and carbohydrate metabolism of D. asperoides from Hubei Province were strong, but their antioxidant capacity was weak. We found that three proteins, UTP-glucose-1-phosphate uridylyltransferase, allene oxide cyclase, and isopentyl diphosphate isomerase 2, may be the key proteins involved in dipsacus saponin VI synthesis. Eight proteins were found in D. asperoides in response to environmental stress from different habitats. Quantitative real-time PCR analysis confirmed the accuracy and authenticity of the proteomic analysis. The results of this study may provide the basic information for exploring the cause of differences in secondary metabolites in different habitats of D. asperoides and the protein mechanism governing differences in quality.
