Lychnophora ericoides is a Brazilian folk phytomedicine from Cerrado's "campus rupestris". Its volatile organic compounds includes bisabolene-derivatives as major compounds. Herein we provide the chemical profiling of constitutive volatile sesquiterpenes from L. ericoides leaves, timeframe emissions surveys, and pollinators records. In situ samples of L. ericoides were harvested. A headspace-solid phase micro extraction method of pre-concentration was optimized. Identification was done through GC-MS. Isolation and structural elucidation were performed whenever necessary. Pollinators were registered in pictures and video. Short time-series and harmonic regressions determined rhythms of single compounds, and average chromatographic signal area was used to determine mono and sesquiterpene rhythms. Concluding, optimized headspace-solid phase micro extraction method of terpenes level analysis was reached. α-Pinene, β-pinene, α-terpinene, para-cymene, limonene, γ-terpinene, terpinen-4-ol, dehydro-sesquicineole, and β-guaiene were identified using GC-MS data. 11-dehydro cadinol and ortho-acetoxy bisabolol were elucidated. Sesquiterpenes concentrations were higher due to temperature rise, lower leaf age, and flowering seasons. Harmonic regressions determined that daylight might control levels of terpenes. Hummingbird, hemiptera insects, and wasps were recorded visiting Compositae capitulum for the first time. We studied nondomestic plants from in situ conditions and concluded that bisabolene-derivative levels were more abundant than monoterpenes during flowering throughout the summer.

野生型山金车(巴西山金车)和传粉记录中挥发性化学符号水平的时间尺度变化

Lychnophora ericoides 是一种来自 Cerrado 的“campus rupestris”的巴西民间植物药。其挥发性有机化合物包括红没药烯衍生物作为主要化合物。在此,我们提供了来自 L. ericoides 叶子的组成型挥发性倍半萜的化学分析、时间框架排放调查和传粉媒介记录。收获了 L. ericoides 的原位样品。优化了一种预浓缩的顶空-固相微萃取方法。通过GC-MS进行鉴定。必要时进行分离和结构解析。传粉者在图片和视频中登记。短时间序列和谐波回归确定单一化合物的节律,平均色谱信号面积用于确定单萜和倍半萜节律。总结,优化了萜烯水平分析的顶空-固相微萃取方法。使用 GC-MS 数据鉴定了 α-蒎烯、β-蒎烯、α-萜品烯、对伞花烃、柠檬烯、γ-萜品烯、萜品烯-4-醇、脱氢倍半萜烯和 β-愈创木烯。阐明了 11-脱氢卡地诺和邻乙酰氧基没药醇。由于温度升高、较低的叶龄和开花季节,倍半萜烯浓度较高。谐波回归确定日光可能控制萜烯的水平。蜂鸟、半翅目昆虫和黄蜂第一次被记录到菊科植物中。我们从原位条件研究了非国内植物,并得出结论,在整个夏季开花期间,红没药烯衍生物水平比单萜更丰富。使用 GC-MS 数据鉴定了 α-蒎烯、β-蒎烯、α-萜品烯、对伞花烃、柠檬烯、γ-萜品烯、萜品烯-4-醇、脱氢倍半萜烯醇和 β-愈创木烯。阐明了 11-脱氢卡地诺和邻乙酰氧基没药醇。由于温度升高、较低的叶龄和开花季节,倍半萜烯浓度较高。谐波回归确定日光可能控制萜烯的水平。蜂鸟、半翅目昆虫和黄蜂第一次被记录到菊科植物中。我们从原位条件研究了非国产植物,并得出结论,在整个夏季开花期间,红没药烯衍生物水平比单萜更丰富。使用 GC-MS 数据鉴定了 α-蒎烯、β-蒎烯、α-萜品烯、对伞花烃、柠檬烯、γ-萜品烯、萜品烯-4-醇、脱氢倍半萜烯和 β-愈创木烯。阐明了 11-脱氢卡地诺和邻乙酰氧基没药醇。由于温度升高、较低的叶龄和开花季节,倍半萜烯浓度较高。谐波回归确定日光可能控制萜烯的水平。蜂鸟、半翅目昆虫和黄蜂第一次被记录到菊科植物中。我们从原位条件研究了非国内植物,并得出结论,在整个夏季开花期间,红没药烯衍生物水平比单萜更丰富。阐明了 11-脱氢卡地诺和邻乙酰氧基没药醇。由于温度升高、较低的叶龄和开花季节,倍半萜烯浓度较高。谐波回归确定日光可能控制萜烯的水平。蜂鸟、半翅目昆虫和黄蜂第一次被记录到菊科植物中。我们从原位条件研究了非国内植物,并得出结论,在整个夏季开花期间,红没药烯衍生物水平比单萜更丰富。阐明了 11-脱氢卡地诺和邻乙酰氧基没药醇。由于温度升高、较低的叶龄和开花季节,倍半萜烯浓度较高。谐波回归确定日光可能控制萜烯的水平。蜂鸟、半翅目昆虫和黄蜂第一次被记录到菊科植物中。我们从原位条件研究了非国内植物,并得出结论,在整个夏季开花期间,红没药烯衍生物水平比单萜更丰富。并且首次记录到黄蜂访问菊科植物。我们从原位条件研究了非国内植物,并得出结论,在整个夏季开花期间,红没药烯衍生物水平比单萜更丰富。并且首次记录到黄蜂访问菊科植物。我们从原位条件研究了非国内植物,并得出结论,在整个夏季开花期间,红没药烯衍生物水平比单萜更丰富。
