Notopterygium franchetii is a herb used in traditional Chinese medicine, where it is known as qianghuo. Its bioactive qualities are influenced by the post-harvest processing methods used (such as drying). However, changes in chemical components according to the drying method are unknown. Fresh roots and rhizomes of N. franchetii were subjected to seven drying methods. Chromatography-mass spectrometry combined with targeted and untargeted analyses were used to investigate relationships between drying methods and chemical concentrations. According to targeted evaluations of the six main bioactive constituents, their total contents decreased significantly in all drying methods. Hierarchical clustering analysis of the drying methods and total metabolome detected 30 chemical constituents, for which heap maps were obtained. Hot air drying was the best processing method, producing the least chemical changes at the lowest cost, while shade drying caused the greatest chemical changes. In conclusion, the wide range of chemical changes in N. franchetii caused by drying was investigated. Such changes potentially affect the quality of herbal medicines.

Nepalese coffee is widely recognized as organic and specialty coffee due to its peculiar aroma and flavor. Altitude, geographical location, orchard management practices, post-harvest handling are the major factors that affect the coffee quality. Coffee quality is determined 40% in the field, 40% at post-harvest primary processing, and 20% at secondary processing. In Nepal, dry and wet methods are the most common coffee processing methods. Wet processed coffee is more preferred by the consumers in comparison to dry coffee and commands higher price. Main objective of the study was to know the most common processing method adopted in Gulmi district and to know the determinants and constraints of the processing method. 100 coffee growers from four different local bodies of Gulmi district were selected by the purposive sampling method for the household survey. Descriptive statistics, logit model and index score ranking method were used for the data analysis. Gender of household head (p <0.01), education level (p<0.05) and technical trainings (p<0.05) were found to have significant effect upon the selection of processing methods. Due to several constraints all coffee growers were unable to adopt wet processing of coffee. Index score method was used to rank the constraints for adoption of wet processing methods. Lack of availability of hand pulpers was ranked as the major constraint by the coffee growers with an index score of 0.867 followed by unavailability of water, no access to transportation as other major constraints for adoption of wet processing method.
