Abstract:
In this study, five phenolic compounds of ginseng rhizosphere soil were identified by HPLC, including gallic acid, salicylic acid, 3-phenylpropionic acid, benzoic acid and cinnamic acid. The results show that five phenolic compounds inhibited mycelium growth and spore germination at high concentration, but promoted mycelium growth and spore germination at low concentration. Gallic acid, salicylic acid, benzoic acid of 0.5 mmol·L-1 and 3-phenylpropionic acid, cinnamic acid of 0.05 mmol·L-1 could significantly promote the spore germination, mycelium growth and disease severity of Cylindrocarpon destructans.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and...
