Abstract
Nearly 80% of the world’s population relies on traditional medicines for primary health care, most of which involve the use of plant extracts. Labiatae are best known for the essential oils common to many members of the family. Types of thricomes, pollen grains and phenloic contents were studied for Thirteen taxa . In the present study, different types of trichomes were studied, four types of non-glandular trichomes and four types of glandular trichomes were distinguished. The study shows that glandular and non glandular trichomes have great value in Lamiaceae taxonomy and a classification key was made. In this study all the pollen grains of the seven studied taxa are hexacolpate pollen grains and have reticulate exine ornamentation and other pollen grains morphology was studied. Also phenolic contents was studied and they were most abundant in Origanum majorana and less abundant in Lavendula hybrid. The results revealed the presence of medicinally important constituents (phenolic compounds) in the plants studied. Many evidences gathered in earlier studies which confirmed the identified photochemical to be bioactive.
