Identification and authentication of Agnimantha plant species used in Ayurveda on the basis of anatomical and molecular phylogenetic analysis

Agnimantha plant species have been used in the Ayurvedic system of medicine for many years and is widely used as an ingredient in many ayurvedic formulations. However, the source for Agnimantha remained controversial as it is difficult to authenticate from various reports. Hence, the present study aims to identify and authenticate its original and substitute sources. As per the literature sources Clerodendrum phlomidis L.f., C. inerme (L.) Gaertn. and Premna serratifolia L. are considered Agnimantha species. The anatomy of the above mentioned species confirmed the presence of patches of up to 20 cells in the sclerenchyma of the root cortex, while in the absence of sclerenchyma of the stem cortex, abundant chambered crystals were also present in the bark of the stem and root in C. phlomidis as compared to C. inerme and P. serratifolia. Phylogenetic analysis using chloroplast (matK, trnH-psbA) and nuclear markers (ITS, rbcl) also indicates the close relation between C. inerme and P. serratifolia and hence places them both in the same clade, though C. phlomidis is closely related to the other species but placed in the adjacent clade. Hence, the study concludes that anatomical as well as molecular phylogenetic analysis reflect close relation between C. inerme and P. serratifolia. while a distant relation with C. phlomidis

Development and standardisation of Laghu Sudarshan Churna – An Ayurvedic polyherbal formulation

106-112Laghu Sudarshan Churna, LSC is an Ayurvedic polyherbal formulation employed for different types of jvaras (fevers). The present study was undertaken to prepare its standardised formulation and to standardise the finished product using quality control procedures mentioned in Ayurvedic Pharmacopoeia of India (API). For this, four batches of the finished products were prepared on a laboratory scale and performed the pharmacognostical parameters (macroscopic, microscopic and powder drug analysis); thin layer chromatography; quantitative physicochemical evaluation including loss on drying, total ash, acid-insoluble ash, alcohol & water soluble extractive values, and pH; & measuring the level of aflatoxins, microbial load, heavy metals and pesticide residues of the finished product. This study is the foremost effort to develop the standardised formulation along with the evaluation parameters for LSC. Thus, obtained results would be beneficial and will act as the reference for the standardisation of LSC

DWT-EMD Feature Level Fusion Based Approach over Multi and Single Channel EEG Signals for Seizure Detection

Brain Computer Interface technology enables a pathway for analyzing EEG signals for seizure detection. EEG signal decomposition, features extraction and machine learning techniques are more familiar in seizure detection. However, selecting decomposition technique and concatenation of their features for seizure detection is still in the state-of-the-art phase. This work proposes DWT-EMD Feature level Fusion-based seizure detection approach over multi and single channel EEG signals and studied the usability of discrete wavelet transform (DWT) and empirical mode decomposition (EMD) feature fusion with respect to individual DWT and EMD features over classifiers SVM, SVM with RBF kernel, decision tree and bagging classifier for seizure detection. All classifiers achieved an improved performance over DWT-EMD feature level fusion for two benchmark seizure detection EEG datasets. Detailed quantification results have been mentioned in the Results section

Pharmacognostic and Preliminary Phytochemical Analysis of Actiniopteris dichotoma Bedd.

The rhizome and fronds of Actiniopteris dichotoma Bedd. has been reported to treat worm infestations, skin diseases, antifertility, diarrhoea and dysentery in Ayurveda. The present investigation involves the macroscopy, microscopy, physicochemical evaluation and preliminary phytochemical studies of Actiniopteris dichotoma Bedd. These observations will help in carrying out further research on this plant.Â

Development of quality control parameters for classical ayurvedic formulation: Vyoshadi Churna

Introduction: Ayurvedic formulations have a long history of use and have increased amazingly to follow the global interest in natural products. However, for many classical ayurvedic formulations, no quality parameters of standardization are available. Vyoshadi Churna, a classical Ayurvedic polyherbal formulation that cures indigestion and diarrhea, is being used since ancient times. However, there is no standard method available for its formulation and evaluation. Hence, the current study aims to develop the quality standards for Vyoshadi churna. Methods: The standard procedures for preparation and standardization of Churna described in Ayurvedic Pharmacopoeia of India (API) were used in the present study. Standardization includes pharmacognostical, chromatographic, and physico-chemical studies. The other essential studies were also done in accordance to API and World Health Organization guidelines to find the limits of microbial load, aflatoxin, heavy metals, and pesticide residue using modern analytical techniques such as gas chromatography-mass spectroscopy (MS) and inductively coupled plasma-MS/MS. Results: Vyoshadi Churna is of brown color and bitter in taste. Pharmacognostical studies have shown the characteristic features of almost each contributory crude drug. A unique chemical profile was also developed using toluene: ethyl acetate: methanol: formic acid (4:4:1:0.5) as the mobile phase to resolve maximum components. Furthermore, the standardized limits for the physicochemical studies, microbial load, heavy metals, aflatoxins, and pesticide residues were established and found in limits. Conclusion: This is for the first time when the standard operating procedure of Vyoshadi Churna was developed. Hence, the current technical work would be practically helpful for the future preparation and standardization study of Vyoshadi Churna
