The cold hardiness of a landscape plant is an important factor in regulating its introduction and cultivation. Thankfully, unsaturated fatty acids in a plant can be used as a determinant of its cold hardiness. The quantities of fatty acids in the leaves of Ligustrum quihoui were analyzed using CHCl 3-CH3OH mixed solvent distilling, pentadecanoic acid internal standard, KOH-CH3OH-BF3 esterify, silica gel discoloration, and finally, gas chromatography. The results concluded that myristic acid was not detectable, but the quantities of palmitic acid, palmitoleic acid, stearic acid, oleic acid, lin...
