“…The leaves and flowers of A. vasica are used as a medicine because they possess many chemical components such as carbohydrates, protein, phenolsas well as flavanoids and alkaloids (8) . A. vasica contains saponins and tannins too (9) , and the roots contain many alkaloids as vasicol, vasicinolone, vasicinone, adhatonine, vasicine and vasicinol (10) . Medicinal herbs are a very important source of medicine throughout human history.…”

The Molecular technique RAPD-PCR used to detect the genotoxicity of different concentrations of aqueous and alcoholic extracts of Adhatoda vasica leaves on onion Allium cepa L. roots. Five concentrations (1%, 2%, 3%, 5%, and 7.5%) and (10%, 15%, 20%, 30% and 40%) were adopted for alcoholic and aqueous extracts respectively. Ten arbitrary primers used in this study, only eight showed polymorphic bands in the gel and two primers were neglected because they did not show any polymorphic bands for all samples. The aim of this study is to detect the toxic effect of the extracts on the root of onion. The emergence and disappearance of bundles in the genome of onion plant Allium cepa L. Treatment with extracts was studied. The genetic relationship tree was established and the genetic distance calculated based on the results obtained from the gel electrophoresis to clarify the toxic effects of the extracts .The results showed that the concentrations that gave the highest effect and the most toxic for aqueous extract is 40% and for the alcoholic extract is 7.5% which are recommended as effective concentrates if used as a pesticide.

Pharmacognosy was initially described by C. A. Sydler as the study of therapeutic plants or products. The physical, chemical, and biological properties are used in these investigations.Adulsa (or Vasaka) is the popular name for the plant Justicia adhatoda (Linn.), which is a member of the Acanthaceae family. Adhatoda leaves have a long history of usage in Ayurvedic medicine, mostly for respiratory conditions. In the current pharmacognostic study of vasaka (leaves), major pharmacognostic techniques such as macroscopy, microscopy, surface preparation, powder characteristics, and physicochemical characteristics were used to identify the presence of trichomes and vascular bundles as well as moisture content, ash values, and extractive values in various parameters.

Background. The aim of the study was to investigate the cytotoxicity, phytotoxicity, and proximate and phytochemical analysis of methanolic extracts of the leaves of Justicia adhatoda. Methods. Methanolic leaf extract of J. adhatoda was screened for phytotoxic activity by using root length inhibition and seed germination assays. Cytotoxic activity was calculated using brine shrimp lethality bioassay. Plant extracts were also investigated for their proximate composition. The presence of several phytochemicals was tested by employing different methods. Results. Decrease in seed germination and root length, 62.67% and 83.11%, was proportional to the increasing concentration of the methanolic extract of the plant. Cytotoxicity assay results indicated that the methanolic extract possessed significant cytotoxic potential with an LC‐50 of 217 µg/ml. Proximate analysis revealed that the leaves of J. adhatoda contain 9.4% moisture, 90.6% dry matter, 19.25% crude protein, 4.5% crude fat, 8.0% crude fiber, and 11.5% total ash. Conclusion. Methanolic extracts of J. adhatoda leaves showed significant cytotoxic effects and may have potential use in medicine. The J. adhatoda foliar extract shows good inhibitory effects against seed germination and root growth. Therefore, it might be used as soil additive in crops to control weeds. Further research is required to detect and isolate phytotoxins from the plant that might replace synthetic herbicides with eco‐friendly herbicides.
