Lehya is a polyherbal preparation which ensure its action from tongue itself. Our preparation acts by inducing anti inflammatory response on various cells, relaxing smooth muscles resulting in bronchodilation and it also has power to simultaneously enhance memory. Being prepared from plant materials it also has other beneficial effects on health and minimum side effects. The prepared lehya was evaluated for various physiochemical parameters. The preparation was evaluated by TLC and FTIR which have been discuss below. The further scope of the preparation can be studies using GC-MS

Liqidambar orientalis have a long standing therapeutic record in Unani System of Medicine.it is commonly known as Shilakali or Turkish sweet gum.  it is obtained from the bark of plant which is known as Mia saila.it has a wide range of pharmacological effects  like Emmenagogue, Aphrodisiac, Diuretic, Antibacterial and general tonic. Various scientific researches revealed that Liqidambar orientalis has Nematicidal activity, Cytotoxic and genotoxic activity. Methods: TLC of different extracts of Liquidambar orientalis was performed for the separation of different components and the Rf values of detected components was noted down accordingly. Results: TLC of different extracts shows various Rf values which suggests the presence of different kinds of phytochemicals which is having a therapeutic significance. Conclusion: TLC analysis along with the other analytical techniques will guarantee the purity, safety, potency and efficacy of herbal drugs. Keywords; Liquidambar orientalis; TLC; Rf value; Scientific evaluation    

Laboratory safety is a very important aspect of science. Without it, experimentation could result in very serious injury. Thin Layer Chromatography is very useful to chemists as an analytical technique to separate and identify the compounds in a mixture using chromatograms. In this technique, the chromatograms must be detected under ultraviolet lamp. The design and working of a new unit, protected ultraviolet cabinet, is presented in this paper. This unit can be used for easy viewing and marking of chromatograms and also for safe laboratory.

Hypochaeris radicata, an edible perennial herb is native of Europe has many medicinal uses which include antimicrobial, antioxidant, antiinflammatory and anticancer activities. The study was aimed at to investigate the phytochemical constituents present in the leaf and root extracts of H. radicata by thin layer chromatography. The results of the study revealed the presence of phytochemical constituents such as alkaloids, flavonoids, saponins, terpenoids and glycosides in the leaf and root extracts of this species. Further, the thin layer chromatographic profiles may serve as characteristic fingerprint for leaf and root extracts of H. radicata. It could be concluded that as the species, H. radicata contained rich variety of phytochemicals, it can be used for drug preparations in pharmaceutical industries.
