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: Erythroxylum monogynum Roxb. (Fam. Erythroxylaceae) is a tree growing up to 9 m in dry evergreen to deciduous forests, distributed in South India mainly on the Deccan plateau, up to 3000 ft. The wood oil possesses characteristic pleasant odour and a pungent taste, hence adulterated with sandalwood oil in perfumery. Traditionally wood oil is used for webbing eczema; bark and wood used for stomach ailments, as a stimulant, diaphoretic, diuretic, for dyspepsia and also for continuous fever. E. monogynum is used as adulterant in the herbal drug market for the heartwood of sandal on account of their morphological and organoleptic resemblances. Objectives: A systematic pharmacognostical study of dried stem heartwood of E. monogynum has been executed to identify the microscopical and phytochemical features. Materials and Methods: Morphology, anatomy, powder microscopy and TLC/HPTLC studies were carried out by standard Pharmacopoeial protocols. Results: Surface characters, odour, taste, arrangement of xylem elements in TS, TLS, RLS, fibres, tailed pitted vessels, tyloses, xylem rays, axial parenchyma with brownish content, tracheids, fibre tracheids, prismatic crystal, crystal fibre and oil globules were the unique diagnostic characters observed. HPTLC showed 5, 6 and 11 bands under 254 nm, 366 nm and white light (post derivatisation with vanillin-sulphuric acid) respectively. The denistogram showed 12, 10 and 13 peaks at UV 254 nm, 366 nm and 520 nm after derivatisation. Conclusion: The findings of the present study will be helpful in identification of this raw drug as a whole or as a powder.

Background: Justicia gendarussa Burm f. of family Acanthaceae is medicinally important herb used in the treatment of inflammatory disorders, asthma, hepatic injuries, pathogenic infection and also shows antiproliferative activity against various cancer cell lines. Materials and Methods: Pharmacognostical evaluation (macro-microscopy, physicochemical analysis and preliminary phytochemical analysis), high-performance thin layer chromatography (HPTLC) fingerprinting and chemical profiling by gas chromatography-mass spectrometry (GCMS) of dried roots of J. gendarussa were done according to quality standard procedures. Results: Microscopic analysis revealed the compact arrangement of cells in cork region and thin-walled cortex beneath epidermis. Parenchymatous cells with xylem vessel were observed in the roots of J. gendarussa. Physicochemical studies revealed loss on drying (10.474\%), total ash (2.990\%), acid-insoluble ash (0.099\%), water-soluble ash (1.528\%), alcohol-soluble extractive value (0.564\%) and water-soluble extractive value (4.11\%) of the raw drug. Preliminary phytochemical analysis of ethanolic extract of J. gendarussa showed the presence of alkaloid, steroid, flavonoid, phenol, carbohydrate, saponin and quinone. Rf, color of the spots and densitometric scan were recorded by HPTLC fingerprinting using toluene: ethyl acetate: formic acid (5.0:4.0:1.0). On photodocumentation, six spots were visualized under 254 nm, nine spots under 360 nm and six spots at 620 nm. Identification of components in ethanolic extract of J. gendarussa was done by GC-MS. GC-MS results in the presence of oleic acid, 9,12-octadecadienoic acid, 6,9,12-octadecatrienoic acid and estra-1, 3,5 (10)-trein-17-β-ol in ethanolic extract of J. gendarussa. Conclusion: These specific identities will be useful in identification and authentication of the raw drug in dried form.
