Using a bioactivity-guided fractionation method, two coumarins: minumicrolineacetonide (1) and epimurpaniculol senecioate (2), were isolated from the leaves ofMurraya omphalocarpa Hayata (Rutaceae).Compound 1 had been previously synthesizedand was now isolated from natural sources for the first time, and compound 2, possessing anegative optical rot
The processes of soil freezing-thawing lead to soil water and heat movement in cold regions, which significantly influences the hydrological and energy cycles in the soil-plant-atmosphere system.This study presents a soil water content coupled with heat transfer model based UMBRELLA on physical processes of water and heat movement in frozen soil.Th
