High performance thin layer chromatographic finger print parameters had been developed for  Piper betle leaf oilisolated from karpoori, sirugamani and vellaikodi variety available in tamilnadu to fix standards. At shorter wavelength (254 nm) resolution was better for, so, this wavelength can be taken for obtaining optimum HPTLC finger printing for  volatile oil of this medicinal plant leaves. As per the data,   Karpoori variety of piper betle leaf oil  only showed  presence of  eugenol content. So, essential oil obtained from this variety should be included in the commercial tooth paste to get  antimicrobial activity against dental pathogens when compared to other studied variety.
