“…The relative content of essential oil constituents is strongly influenced by the drying method (Mirhosseini et al 2015). α-Pinene is one of the most important components of rosemary essential oil that has many applications in various industries, so its high content indicates the high quality of the essential oil (Risner et al 2020). Monoterpenes, followed by alcohols and sesquiterpenes, are the main constituents of rosemary essential oil (Szumny et al 2010).…”

Background Preharvest and postharvest conditions of medicinal plants strongly affect the quantity and quality of their secondary metabolites. Here, the effect of different harvesting times (5 am, 12 noon and 5 pm) and different drying methods (shade at 25 °C, oven at 60 °C and microwave at 180 W) on essential oil content and components, total phenol content and antioxidant activity of rosemary was monitored. Results Harvesting time only had a significant effect on the essential oil content and components; however, all investigated traits were significantly affected by drying methods. The essential oil content of plants harvested at 5 am and 5 pm was higher than those harvested at 12 noon. The highest amount of essential oil was obtained from shade (0.85–1.12%) and oven (0.66–1.04%) dried plants, respectively. Total phenol and antioxidant activity of oven dried plants were significantly lower than shade and microwave-dried plants. The number, type and amount of essential oil components were affected by harvesting time and drying method. α-Pinene, verbenone and camphor were the major components of the essential oils. Oxygenated monoterpenes were the main group of essential oil compounds in all treatments. The results of biplot and cluster analysis, based on the measured traits, placed the treatments in three separate clusters; I: shade dried, II: oven-dried, and III: microwave-dried plants. Conclusion Generally, to obtain the higher essential oil content, phenol and antioxidant activity, harvesting at 5 am and 5 pm and also shade drying are recommended; however, for reaching to essential oil with specific quality, different harvesting time and drying method could be used.

The Australian Wet Tropics World Heritage Area (WTWHA) in northeast Queensland is home to approximately 18 percent of the nation’s total vascular plant species. Over the past century, human activity and industrial development have caused global climate changes, posing a severe and irreversible danger to the entire land-based ecosystem, and the WTWHA is no exception. The current average annual temperature of WTWHA in northeast Queensland is 24 °C. However, in the coming years (by 2030), the average annual temperature increase is estimated to be between 0.5 and 1.4 °C compared to the climate observed between 1986 and 2005. Looking further ahead to 2070, the anticipated temperature rise is projected to be between 1.0 and 3.2 °C, with the exact range depending on future emissions. We identified 84 plant species, endemic to tropical montane cloud forests (TMCF) within the WTWHA, which are already experiencing climate change threats. Some of these plants are used in herbal medicines. This study comprehensively reviewed the metabolomics studies conducted on these 84 plant species until now toward understanding their physiological and metabolomics responses to global climate change. This review also discusses the following: (i) recent developments in plant metabolomics studies that can be applied to study and better understand the interactions of wet tropics plants with climatic stress, (ii) medicinal plants and isolated phytochemicals with structural diversity, and (iii) reported biological activities of crude extracts and isolated compounds.
