Phytochemical screening and HPTLC fingerprinting of leaf extracts of Psidium guajava Linn. Rashmi Tambe, R.G Singhal, Kiran Bhise, Maushumi Kulkarni ABSTRACT Objective: To establish physical constants and fingerprint profile of Psidium guavaja Linn using high performance thin layer chromatography (HPTLC) technique. Amongst the most powerful chromatography an inert solid material such as techniques available to the analyst for the silica gel or diatomaceous earth serves to support a separation of these mixtures are group of highly thin layer of liquid which is the effective stationary efficient methods collectively called phase.

The obtained extracts were further analyzed for antimicrobial effect against Gram Positive as well as Gram negative bacteria and combined effect of extract and antibiotics was also studied. The phytochemical compounds were analyzed through thin layer chromatography and were screened for isolation of bioactive compound. Here, an online simultaneous TLC-MS analysis system, liquid thin layer chromatography – mass spectrometry (LTLC-MS), is developed which successfully synchronize TLC separation process and MS detection process like GC-MS and HPLC-MS do. And there's no need to use specially designed TLC, just regular TLC plates are enough.
