The present study deals with manifests the typical plant diversity
of Himalayan region of Kaghan Valley, Pakistan. The morphological
and palynological studies including light microscopy and Scanning
Electron Microscopy (SEM)has done on 40 species and 22 genera of 21
families. This study is very fruitful results as all selected
plants are medicinal and have very strong ethnobotanical
characteristics, and the work done has given the key to
identification of following medicinal plants for further
Pharmacognostic and taxonomical studies in future.
This work has two parts one is taxonomic studies and the second is
phytochemical screening. The work was carried out to study the
morpho-anatomical and palynological characters in order to advance
knowledge on these medicinal plants and on pharmacognostic quality
control. The plant material was fixed and prepared according to
light microscopy (LM) and scanning electron microscopy (SEM).
Preliminary phytochemical screening of herbal formulations is
essential in order to assess the quality of drugs, based on the
concentration of their active principles, physical and chemical
standards. Quantitative and qualitative investigation of the
phytoconstituents including alkaloids, saponins, steroids,
flavonoids and phenols of these medicinal plants, Vateria indica
L., Catharanthus roseus L., Boswellia serrata Roxb., Carum carvi
L., Trachyspermum ammi L., Anethum graveolens L., Foeniculum
vulgare Mill., Ruta graveolens L., Nigella sativa L., Commiphora
mukul Hook ex Stock. And Shellac was investigated. The analysis of
the ash residues of the part used of these medicinal plants was
performed for their quality assurance including total ash, acid
insoluble ash and water soluble ash contents.
This book deals with the taxonomical studies including morphology,
leaf epidermal anatomy and pollen and palynology of the grasses
(monocots) of Thar desert of Sind, Pakistan. The study has
conducted on 39 species belonging to 56 genera of 8 tribes in 4
subfamilies of Poaceae from District Tharparkar. The objective of
the study was to identify and classify the plants on the basis of
systematic studies and to study the intraspecific, intrageneric and
intergeneric relationships among species of different genera and
tribes.
