Objective: To study the volatile compounds from inflorescence of Cistanche deserticola and provide basis for its utilization and seed breeding.
Methods: The volatile compounds were collected by dynamic headspace adsorption and analyzed by gas chromatography-mass spectrometry (GC-MS).
Results: Forty volatile components were identified in inflorescence of Cistanche deserticola from squaring period to full-bloom period. The main components in buds of Cistanche deserticola were hydrocarbons and green leaf volatiles in squaring period. Some components were characteristic in buds and disappeared or decreased in flowers. The relative contents of some components gradually increased with the buds blooming. And some components only emerged in flowers of Cistanche deserticola. The higher content of esters and aromatics were found in flowers, which were significantly increased in comparison with the volatile compounds from buds.
Conclusion: The volatile compounds from inflorescence of Cistanche deserticola were complex, consisting of various compositions and significantly different with buds blooming.

Common adhesives for nonstructural applications are manufactured using petrochemicals and synthetic solvents. These adhesives are associated with environmental and health concerns because of their release of volatile organic compounds (VOCs). Biopolymer adhesives are an attractive alternative because of lower VOC emissions, but their strength is often insufficient.

Monitoring volatile organic compounds (VOCs) is crucial for ensuring safety and health. In this study, we introduce a strategy to engineer a chromatography-inspired single-sensor (CISS) e-nose tailored for VOC monitoring. This approach overcomes the limitations of traditional methodologies and conventional e-noses.

Insects and flowering plants are the most abundant and diverse multicellular organisms on Earth, accounting for 75% of known species. Their evolution has been largely interdependent since the so-called Angiosperm Terrestrial Revolution (100-50 Mya), when the explosion of plant diversity stimulated the evolution of pollinating and herbivorous insects. Plant-insect interactions rely heavily on chemical communication via volatile organic compounds (VOCs).

The evolutionary success of angiosperms, which make up more than 95 percent of the world's terrestrial flora, is largely based on their interactions with animal pollinators. Indeed, it is estimated that, on average, 87.5 percent of flowering plants are pollinated by animals.
