AI Article Synopsis

  • Cinnamomum cassia, a subtropical plant used for food and medicine, has had its suitable habitats affected by climate change, which may impact the effectiveness of herbal remedies.
  • The study highlights that key environmental factors like precipitation, temperature, and soil affect the distribution of C. cassia, with optimal habitats currently found mainly in southern China, but likely shifting northward by the 2090s.
  • Analytical methods like HPLC and FTIR can help differentiate the quality of C. cassia from various habitats, revealing that higher-quality plants contain more trans-cinnamaldehyde in more suitable environments.

Article Abstract

Cinnamomum cassia Presl. is a subtropical plant that is used for food and medicine. Climate change has changed the suitable habitats of medicinal plants, which might have repercussions for the efficacy of herbal remedies. In this study, the potential distribution in each period of Cinnamomum cassia was predicted and the quality in different suitable habitats was evaluated. According to the results, (1) precipitation, temperature, and soil are the primary environmental variables influencing C. cassia distribution. (2) The high-suitable habitats of current climate scenarios were predominantly located in the southern regions (Guangdong and Guangxi etc.) of China, with an area of 706,129.08 km. Under future climate scenarios, suitable habitats will increasingly move northward, with a greater concentration south of the Yangtze River, particularly in the 2090s SSP585 scenario, the total area of newly extended suitable habitat reaches 312,963.53 km. (3) HPLC and FTIR, combined with chemometrics, can be effective methods for identifying different suitable habitats of C. cassia. The content of trans-cinnamaldehyde (0.85%) is significantly higher in the high suitability habitat compared to the medium-low suitability habitat (0.30%). Our findings can offer valuable guidance for the identification of suitable C. cassia cultivation areas in China, as well as for the evaluation of C. cassia resource quality and the rational use of resources in different suitable habitats.
