ABSTRACT
Churna are important group of formulation used by Ayurvedic physicians to treat various types of diasease. Trikatu and Pimpali churna, as per Ayurvedic literature is used for the treatment of resperatory disorders. In the present study,an attempt has been made to develop a HPTLC  method of quantitative estimation of marker compound, piperine in laboratory prepared authentic formulation and a marketed formulation of Trikatu and Pimpali churna. The stationary phase used was precoated silica gel G ₆₀ F ₂₅₄ plates. The mobile phase containing n- Hexane-ethyl acetate, (5:5 v/v ), was used to separate the spot of Piperine. Plates were developed to a distance of 8 cm at room temperature. Spectrodensitometric scanning was performed by TLC scanner III (CAMAG) in absorbance mode at the wavelength of 339nm. The  R_f  values of  piperine was 0.44± 0.02. The method was validated in terms of Linearity, Accuracy and  Precision. The linearity curve found to be linear in between 200–900 ng/spot. The limit of Detection (LOD) and limit of Quantification (LOQ) were found to be  1 ng and  3 ng respectively. The mean results from % Recovery was found to be, laboratory formulation contain 85.13% and 83.47% while the commercial formulation shows 96.65%, and 90.32% respectively. The proposed method can be used to determine Piperine from Ayurvedic formulations.

Abstract:  
Peptic ulcer is a condition where benign lesions of gastric or duodenal mucosa occur at a site where the mucosal epithelium is exposed to acid and pepsin, due to imbalance between offensive and defensive factors. Acacia leucophloea, a deciduous tree found throughout India is reported to be used in gastric ulcer in traditional medicine. The present study was undertaken to evaluate the anti-ulcer properties of Acacia leucophloea in pylorus ligation ulcer model in rats. Acacia leucophloea was administered for 7 days and on 8^th day 30 min prior to the induction of ulcers. Pretreatment with Acacia leaucophloea showed significant ulcer protection against pylorus ligation ulcer model as compared to control. Thus, the ulcer protective and healing effects of Acacia leucophloea may be due to its effect on both offensive and defensive factors. The present findings suggest that Acacia leucophloea has antiulcer properties.
