Objective: To develop an HPLC method for estimation of psoralen, bakuchicin and bakuchiol in Psoralea corylifolia. Materials and methods: An gradient, reverse phase (RP) HPLC procedure using a mixture of Phosphate buffer and acetonitrile as mobile phase, C18 column as stationary phase and UV detector. Results: The developed method shows high resolution, accuracy and reproducibility. Conclusions: The method developed is accurate, precise and specific.Keywords

Objective: Estimation of wedelolactone (WDL) and demethylwedelolactone (DWDL) in Eclipta alba Hassk. by HPLC. Materials and methods: An Isocratic, reverse phase (RP) HPLC procedure for the standardization of Eclipta alba using a mixture of 0.1% v/v Ortho phosphoric acid and acetonitirile as mobile phase C8 column as stationary phase and photo diode array detector. Results: The above method shows high resolution, accuracy, economical and reproducibility. Conclusions: The method developed is useful in standardization of Eclipta alba material.Keywords

Objective: To develop an improved HPLC method for estimation of phyllanthin and hypophyllanthin in Phyllanthus amarus. Materials and methods: An Isocratic, reversed phase (RP) HPLC procedure has been adopted using a mixture of pH 2.8 Phosphate buffer and acetonitrile as mobile phase, CN column as stationary phase and UV detector. Results: The developed method shows high resolution (R = 1.9), accuracy and reproducibility. Conclusion: The method developed is relatively better in terms of separation than the previously reported methods.Keywords

Objective: Detection of pyrrolizidine alkaloids (PA) in some polyherbal formulations. Materials and methods: Silica gel TLC with specific spray reagent for PA. Results: None of the herbal formulations tested were positive for PA. Phyllanthus amarus ischolar_mains were found to contain PA. Conclusion: TLC method is recommended for routine detection of PA in plant drugs.Keywords

Objective: The experiment was conducted to know the effect of aging on andrographolide content in Andrographis paniculata (Kalmegh) to establish the best harvesting time. Materials and method: The growth and yield parameters were studied at 30, 60, 90, 120 and 150 days after sowing. The andrographolide content was estimated by HPLC method. Results and conclusion: The best harvesting time was observed at 120 days after sowing to get higher biomass containing maximum andrographolide content.Keywords
