Introduction: Achyranthes is a well-known herb used in folk lore and traditional systems of medicine for its therapeutic value. The two species Achyranthes aspera and Achyranthes bidentata are used interchangeably by people and by herbal industries due to their resemblance in appearance. Therefore, the present study was undertaken to evaluate the comparative pharmacognostic and pharmacological properties of both species. Methods: Pharmacognostic characters were evaluated as per the guidelines of Ayurvedic Pharmacopoeia of India. A quantitative HPTLC method was developed for quantification of linoleic acid and oleanolic acid using toluene: ethyl acetate: formic acid (6: 4: 0.5 v/v/v) as a mobile phase. Quantification was performed using linear regression analysis by plotting the peak area vs concentration curve with 2000-5000 ng/band (R2 = 0.998) for oleanolic acid and 2000-5000 ng/band (R2 = 0.994) for linoleic acid. The developed method was validated in terms of accuracy, recovery and inter and intraday study as per ICH guidelines. Antioxidant activity of methanolic extracts was estimated by five different models viz. DPPH free radical scavenging assay, total anti-oxidant capacity, reducing power assay, total flavonoid and phenol content. Anti-diabetic activity was analyzed by \α-amylase inhibition assay using 3, 5 di nitro salicylic acid and iodine starch model. Results: The limit of detection (LOD) and limit of quantification (LOQ) of oleanolic acid and linoleic acid were determined, respectively, as 0.426, 1.29 and 0.427, 1.29 \μg mL\−1. Inhibition of free radicals increases with concentration and IC50 of A. aspera and A. bidendata was obtained at 1.35 \± 0.173 mg/ml and 1.28 \± 0.169 mg/ml respectively. In in vitro antidiabetic activity, IC50 value shows that A. bidentata exhibit better activity than A. aspera. Conclusion: The present study generates data for the proper establishment of quality control standards of the crude drug.

Objective: To develop a novel analytical method for simultaneous determination of two triterpenic acids by high-performance thin layer chromatography in methanol and dichloromethane extracts of Eucalyptus globulus leaf. Ursolic acid was also isolated from Eucalyptus globulus leaf. Materials and Methods: Two triterpenic acids (ursolic and oleanolic acid) were extracted using methanol and dichloromethane as the extraction solvents. Study for total triterpenoids present in Eucalyptus globulus leaves was carried out which shows considerable amount of terpenoids present. Because of the similarity of chemical structure, the prechromatographic derivatization was necessary to separate these triterpenic acids. The samples were treated by 1\% iodine solution in chloroform directly on the chromatographic plate and developed with the mobile phase consisting of petroleum ether, ethyl acetate and acetone (7.8:2.2:0.1, v/v/v). After drying, the plates were sprayed with 10\% (v/v) ethanol solution of sulfuric acid and heated to 120 \°C for 3 min. Quantification was performed in absorbance/transmittance mode at a wavelength of 345 nm. The developed HPTLC method was validated for linearity, precision and accuracy. Results: Correlation coefficient (r2 \> 0.99), R.S.D. values, detection limits as well as recovery values were found to be satisfactory. Ursolic acid was isolated from E. globulus leaves. The identification of isolated ursolic acid was done on the basis of Rf value (0.26) for HPTLC and peak interpretation for FT-IR. Conclusion: The method has been successfully applied in the analysis of both triterpenic acids in medicinal herbs.

The present study was carried out to evaluate the quality control analysis and antiproliferative effects of petroleum ether, chloroform, ethanol and aqueous extracts of Swertia alata (family Gentianaceae) on Leishmania donovani. A basic, exact, quick and reproducible high performance thin layer chromatography (HPTLC) has been created for synchronous analysis of Oleanolic acid and Swertiamarin from S. alata.

Background: Mollugo oppositifolia, is one of the plants commonly used as, \‘Parpata\’ by Ayurvedic practitioners. It is indicated as a bitter tonic, antiseptic and febrifuge. Aim: To generate and ensemble data of physical parameters for ascertaining the identification and to develop validated HPTLC method for quantification of oleanolic acid and lupeol in M. oppositifolia. Materials and Methods: M. oppositifolia was studied for establishing pharmacognostic standards including macro and microscopical characters, physico-chemical analysis and quantification of oleanolic acid and lupeol by HPTLC method. Results: It is an annual, prostrate herb with linear-lanceolate leaf and white coloured flower. Microscopically root can be characterized by crescent shaped phloem associated with continuous or discontinuous rings of xylem; stem by epidermis bearing multi-cellular simple and glandular trichomes, and sclerenchymatous pericycle; and leaf by continuous band of a palisade cells and rosettes and prisms of calcium oxalate throughout parenchyma. Powdered drug can be typified by multi-cellular trichomes, fragments of epidermis of leaf in surface view, epidermis of corolla and entire or broken seeds. Saponins and flavanoids were found be the major components. HPTLC method was developed for quantification of oleanolic acid and lupeol using precoated silica gel plates as a stationary phase, and toluene: methanol (9.4: 0.6) as a mobile phase and scanning the plate at 545 nm. The amount of oleanolic acid and lupeol were found to be 0.027-0.029\% w/w and 0.015-0.016\% w/w respectively. Conclusion: The quality parameters and HPTLC method developed would serve as useful gauge in standardization of Mollugo oppositifolia.
