Key Findings

  • The study analyzed the essential oils of three lavender species grown in the Ili region from 2019 to 2023
  • Taikong blue lavender showed greater stability in its volatile organic compounds compared to the other two varieties
  • The stable composition of Taikong blue lavender makes it a reliable option for essential oil production, ensuring consistent quality and aroma
Lavender (Lavandula angustifolia Mill.) is renowned for its aromatic properties and potential therapeutic benefits. A recent study conducted by the Shanghai Institute of Technology investigated the differences in volatile organic compounds (VOCs) within the essential oils (EOs) of three lavender species—H70-1, French blue, and Taikong blue—grown in the Ili region from 2019 to 2023[1]. The study aimed to provide insights into the stability and quality of these EOs, which are crucial for their commercial and industrial applications. The research employed sensory evaluation, gas chromatography-ion mobility spectrometry (GC-IMS), and gas chromatography-mass spectrometry (GC-MS) to analyze the VOCs. Sensory evaluation involves human testers assessing the aroma, while GC-IMS and GC-MS are advanced techniques for identifying and quantifying chemical compounds. The findings revealed that Taikong blue lavender exhibited greater stability in VOC composition compared to the other two varieties, making it a more reliable option for EO production. Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA) was utilized to distinguish the aromas of the three EOs effectively. This statistical method helps in identifying patterns and differences in complex data sets. By combining odor activity value (OAV) and variable importance in projection (VIP) values, the researchers identified five VOCs that were crucial for discriminating among the three lavender EO types. This study builds on previous research highlighting the therapeutic benefits of lavender. For instance, lavender has been shown to have significant sedative and hypnotic effects when inhaled, making it a promising alternative to traditional psychotropic substances[2]. Additionally, lavender has been found to be effective in reducing anxiety and pain, improving sleep quality, and stabilizing vital signs in cancer patients[3]. Another study demonstrated that inhaled lavender could improve sleep quality and mood in diabetic patients suffering from insomnia, without affecting metabolic status[4]. Moreover, a systematic review and meta-analysis confirmed lavender's efficacy in reducing depression severity, further supporting its mental health benefits[5]. The current study's findings offer valuable theoretical support for the cultivation and commercialization of lavender as an industrial crop in the Ili region. The stability of Taikong blue lavender's VOC composition makes it particularly suitable for EO production, ensuring consistent quality and aroma. This is crucial for industries relying on lavender EO, such as aromatherapy, cosmetics, and pharmaceuticals. In conclusion, the research conducted by the Shanghai Institute of Technology provides a comprehensive analysis of the VOCs in different lavender species, highlighting the superior stability of Taikong blue lavender. This study not only advances our understanding of lavender EO's chemical composition but also reinforces its potential therapeutic benefits, building on previous findings related to its sedative, anti-anxiety, and antidepressant effects.
