Background: Traditional medicine has become part and parcel of the present era for the maintaining and preventing of ailments. Alternanthera brasiliana and Alternanthera paronychioides (Amaranthaceae) are widely used in traditional medicine. Ab is widely familiar as penicillin in Brazil. Ap is known to treat gout, hyperuricemia, rheumatic arthritis, nephritis etc. as folk medicine. The present study aims to compare standardization profiles for A. brasiliana and A. paronychioides. Materials and Methods: Sample Ab and Ap were collected and authenticated. Authenticated samples were subjected to powder microscopy, physico-chemical, phytochemical, HPTLC and HPLC fingerprint and PXRD analysis. Results: Powder microscopic investigations revealed the characteristic features for identification. Physico-chemical investigation revealed the slightly acidic nature of both plants. The phytochemical test showed the existence of phenol, terpenoids and steroids as major secondary metabolites in both species. Photo documentation, fingerprints and spectral comparison by HPTLC and fingerprints by HPLC validate the existence of similar compounds in both Ab and Ap. PXRD analysis revealed the variance of elements present in both species. Conclusion: Comparative physico-chemical, phytochemical and HPLC, HPTLC, and P-XRD instrumental analysis of A. brasiliana and A. paronychioides provides distinct features for identification.

Background: The Solanaceae family member Datura metel L. has been related to therapeutic benefits. The plant is widely used in Ayurveda and Siddha systems of Indian medicines. Objectives: Present study was focused to understand the phytochemical and multi elemental composition of D. metel whole plant. Materials and Methods: The whole plant of D. metel was collected, shade dried, powdered and subjected to analysis of physico-chemical parameters, thin layer chromatography, high performance thin layer chromatographic finger print profilings (HPTLC), high pressure liquid chromatographic profile at four wavelengths, X-ray fluorescence, energy dispersive X-ray analysis, X-ray photoelectron spectrometer, powder X-ray diffractometer and inductively coupled plasma optical emission spectrometer. Results: In HPTLC, 7 spots under 254 nm, 10 spots under 366 nm and 11 spots after derivatization with vanillin sulphuric acid reagent appeared. In HPLC, 9 peaks at 230 nm, 11 peaks at 254 nm, 5 peaks at 286 nm and 7 peaks at 366 nm separated. Presence of 17 elements such as copper, cobalt, nickel, manganese, zinc, iron, sodium, potassium, calcium, magnesium, phosphorus, aluminium, chlorine, carbon, oxygen, sulphur and silicon were identified. Conclusion: The elements K, Mg, Ca, Si, S and Fe play vital role on human health. Chlorine, silicon, sulfur and silica are first time identified which have significant biological functions.
