INTRODUCTION
Nature always stands as a golden mark to exemplify the outstanding phenomenon of symbiosis. The biotic & abiotic elements of nature are all interdependent. The plants are indispensable to man for his life. The knowledge of drug has accumulated over  thousands of years as a result of man’s inquisitive nature so that today we posses many effective means of ensuring health care.
In the part, almost all the medicines used were from the plants, the plant being men’s only chemist for ages. The history of medical plants dates back to RIG VEDA, perhaps the oldest repository of human knowledge, which was written in about 4500-1600 B.C. then there is the Ayurveda which given us detail accounts of many herbal drugs. Most of the medicinally active substance are identified in the 19^th & 20^th centuries was used in crude form. But now in modern days we use to take drug in the form of dosage form.

Abstract
Plants and their extracts have immense potential for the management and treatment of wounds. Wound healing is complicated process that involves four phases: (i) coagulation begins immediately after injury, (ii) Inflammation which begins within hours, (iii) Proliferation which begins within days, (iv) Remodeling up to period of week, months, up to year. The phyto medicine for wound healing are not only cheap and affordable but are also purportedly safe as hypersensitive reactions are rarely encountered with the use of these agents. Mainly these crude drugs are obtained from various climatic conditions Collection, cultivating, Harvesting & Isolation of active ingredients to treat various types of diseases.

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.
