COEFFICIENT/LOGP: LogP value refers to the logarithmic value of the partition coefficient of a substance in the system of n-octanol/water, it reflects the distribution of the substance in the oil-water two-phase system.
The higher the LOGP value, the more hydrophilic the substance is.
The lower the LOGP value, the more hydrophilic the substance is.
Synthesis method of CAFFEIC ACID
1. The Roots and stems of Cimicifuga were extracted with methanol and concentrated with methanol under reduced pressure. The residue is dissolved by heating water, and the insoluble material is removed by filtering while it is hot. After cooling, benzene is added and the benzene solution is washed with 1% Sodium bicarbonate water to collect the washing solution. Add Dilute hydrochloric acid acidification, benzene and then free from the organic acid, reduced pressure concentration of benzene, residue for caffeic acid enrichment products.
2. TOBACCO: FC, 53,54. From the acid hydrolysis of chlorogenic acid.
Purpose
CAFFEIC ACID intermediate. For Organic Synthesis.
2. The utility model can be used safely in cosmetics, and has wider antibacterial and antiviral activities. It absorbs ultraviolet light. At low concentrations, it is helpful to enhance the intensity of color and luster by inhibiting the auxiliaries of hair dyes for skin.
