Introduction: Comparative powder microscopic and HPTLC studies were carried out on stem barks of Symplocos racemosa Roxb. and Symplocos crataegoides Ham. to differentiate its identity in Ayurvedic formulations. Method: Powder microscopic and HPTLC studies of these barks were undertaken on a comparative basis and results are reported in this paper. The authentic samples are cleaned, powdered and passed through sieve No. 80. A few mg of powder was stained with saffranin, Toluidine blue and Iodine and photographed under different magnifications with the help of NICKON Labphot -2. HPTLC studies were followed by Sethi and Wagner et al method. Results: The colour, taste, cork cells, fibres, sclereids, starch grains, calcium oxalate crystals, number of spots and Rf values of HPTLC are found to be differentiating diagnostic characters in powdered form of S. racemosa and S. crataegoides. Conclusion: The findings of the present study is believed to be helpful in standardization of Ayurvedic formulation containing stem bark of S. racemosa and S. crataegoides as ingredients in powder form. The study sets the specific microscopic protocol and HPTLC finger print of the two drugs and may lead to global acceptance and reputation of the Ayurvedic system.

Context: The stem barks of the plant Symplocos crataegoides Buch.-Ham. ex D. Don (syn. Symplocos paniculata (Thunb.) Miq.), Fam. Symplocaceae is extensively used in Indian medicine under the names of Lodhra/Patikalodhra. Mainly it is used to cure uterine complaints, vaginal and menstrual disorders. Aim: To investigate the phytochemicals from the n-hexane extract of the stem bark of Symplocos crataegoides Buch.-Ham. ex D. Don., using GC-MS analysis. Materials and Methods: Stem bark of S.crataegoides was extracted by Soxhlet extraction method using n-hexane. The extract was injected by splitless injection mode into the GC MS 5975 C Agilent equipped with a QP- 5000 (quadrupole) Gas Chromatography - Mass Spectrometer. Results: Identification of 57 compounds from n-hexane extract. Those compounds were identified by close matches with standard MS spectra and compared with NIST - 11 and WILEY library data. Undecane (7.51\%) was found as major compound followed by Isopropyl myristate, Dodecane, 1,2,4-trimethyl-benzene, Octacosane, 2-methyl-decane, 2-ethyl-1,2-dimethyl-benzene, 1,2,3,5- tetramethyl-benzene etc., other constituents were found to be in traceable quantities. Conclusion: GC-MS analysis of S. crataegoides revealed certain interesting facts of presentation of various phytoconstituents in the stem bark. The presence of various phytoconstituents contributes to the medicinal activity of the plant.
