New Quaternary Alkaloids from Vinca minor.
Three new quaternary bases were separated from the most polar fraction of the crude methanolic extract of lesser periwincle ( VINCA MINOR L.) leaves. Their structures were elucidated by spectroscopic methods as 4-methylraucubainium chloride, 4-methylstrictaminium chloride, and 4-methylakuammicinium chloride.
