A fast field-deployable method utilizing Raman spectroscopy to determine the optimal harvest time of plants extract highest abundance target metabolites is presented. Rosmarinic acid a metabolite extracted from spearmint (Mentha spicata L.). Leaves commercial “Native” and proprietary clonal line “KI110” were measured as function cell type age rosmarinic abundance. linear regression model with l...

Model selection and hyperparameter optimization is crucial in applying machine learning to a novel dataset. Recently, a subcommunity of machine learning has focused on solving this problem with Sequential Model-based Bayesian Optimization (SMBO), demonstrating substantial successes in many applications. However, for computationally expensive algorithms the overhead of hyperparameter optimizatio...

BACKGROUND In aromatherapy, essential oils are used as anti-inflammatory remedies, but experimental studies on their action mechanisms are very limited. AIMS OF THE STUDY To assess their anti-inflammatory activities, the effects of essential oils on neutrophil recruitment in mice were examined in vivo. METHOD The effect of essential oils on leukocyte and neutrophil recruitment induced 6 h a...

This study presents a comparison of the quality characteristics spearmint (Mentha spicata L.) dried by photovoltaic thermal dryer (PDS), shade (SDS), and an oven (ODS). The samples obtained were evaluated with respect to volatile compounds (VC), total phenolic (TPC) flavonoid content (TFC), antioxidant capacity (AC) chlorophyll contents. PDS had highest amount TPC, TFC AC, while SDS ODS did not...
