This paper presents the experimental analysis of data provided by UCI machine learning repository. Weka open source machine learning tool provided by Waikato University reveals the hidden fact behind the datasets on applying supervised mathematical proven algorithm, i.e., J48 and Naïve Bayes algorithm. J48 is an extension of ID3 algorithm having additional features like continuous attribute value ranges and derivation of rules. The data sets were analyzed using two approaches, i.e., first taken with selected attributes and taken with all attributes. The performance of both the algorithm reveals the accuracy of algorithm and predicting the various reasons behind this increasing problem of cardiovascular diseases. © Springer Nature Singapore Pte Ltd. 2017.

The chloroform extract of Swertia cordata (G. Don) roots was subjected to column chromatography, afforded two (one new and one known) xanthones. Both the compounds were isolated for the first time from S. cordata. The structures of the isolated compounds were established on the basis of melting point,1D (1H NMR & 13C NMR) and 2D (1H 1H COSY, HSQC & HMBC) NMR spectroscopy, in addition to high-resolution mass spectrometry. © 2016 Informa UK Limited, trading as Taylor & Francis Group

The purpose of this paper is to develop Artificial Neural Network (ANN)-based apple classifier. Testing effort is calculated using ANN method. The complete system is divided into two modules. In the first module, input (surface level apple quality parameter) from the different sources is collected by the software developed in Visual Basic through different input device like web camera, weight machine, etc. In the second module, the input data are used by ANN simulator to classify the apple according to their quality. The final result of an ANN model for apple classification is discussed; however, the modeling results showed that there is excellent agreement between the experimental data and predicted values. A low level of error prediction confirmed the fact that the Neural Network model is an effective instrument of the apple quality estimation. There is not any misclassification during testing. The paper presents alternative method for quality assessment of apple and provides consumers with a safer food supply. © 2012 Springer-Verlag London Limited.

This study was designed to examine the in vitro antimicrobial activity of methanol extract of Buddleja asiatica Lour, leaves and flowers. The inhibitory effects were tested against 6 bacterial (Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Proteus vulgaris, Bacillus mycoides) and 2 fungal (Aspergillus niger, Candida albicans) strains using disc diffusion method. The results showed that the flowers extract exhibited good antimicrobial activity as compared to the leaves extract. © 2012 Academic Journals Inc.

The essential oil of Lobelia pyramidalis was analyzed by GC and GC-MS. A total of 21 con-stituents comprising 77.88% of the total oil were identified. Perilla ketone constituted 25.61% of the oil followed by camphorquinone (12.16%), dibutyl phthalate (10.66%) and allyl nonanoate (8.47%). The antimicrobial activity of the oil was evaluated using the disc diffusion method and the microdilution technique. The results showed that the oil exhibited moderate antimicrobial activity.

The chemical composition of the essential oil obtained from the leaves and roots of Senecio rufinervis DC. was analyzed by GC, GC/MS and NMR. Germacrene D was the major constituent in both the oils studied (40.19 and 24.95%, respectively). The antimicrobial activity of the oil was determined by disc diffusion method. Results showed that both the oils exhibited significant antibacterial activity.

The study aim was to evaluate the concentration of mineral elements and antimicrobial activity of Swertia cordata (G. Don) Clarke aerial parts and roots. Macro minerals, viz. sodium, potassium, calcium, lithium were estimated by Flame Photometer while micro minerals, viz. iron, copper, manganese, zinc and cobalt were determined by Atomic Absorption Spectrophotometer. Among all the elements, highest concentration of potassium was recorded in both aerial parts (385.6 mg/100 g) and roots (421.3 mg/100 g) of S. cordata. Methanol extract of both S. cordata aerial parts and roots obtained by Soxhlet extraction were screened for their antimicrobial activity against 6 bacteria and 2 fungi using disc diffusion method. The results showed that both the extracts exhibited moderate antibacterial activity while roots showed good antifungal activity against Candida albicans (ZOI =20 mm).

An attempt has been made to analyse macro and micro elements in three medicinal plants (Solidago canadensis, Buddleja asiatica and Leucas hyssopifolia) collected from different regions of Uttarakhand, India. Macro minerals viz., sodium, potassium, calcium, lithium were estimated by Flame Photometer while micro minerals viz., iron, copper, manganese, zinc and cobalt were determined by atomic absorption spectrophotometer. Among all the elements, highest concentration of calcium was recorded in all of the three plants followed by potassium and sodium. Macrominerals such as sodium, potassium, calcium were present in greater amount in L. hyssopifolia while S. canadensis was found to be richer in microminerals. © 2013 Academic Journals Inc.

This paper describes a new apple classification system based on machine vision and artificial neural network (ANN), which classifies apple in real time on the basis of physical parameters of apple such as size, color and external defects. A specific hardware subsystem has been developed and described for every stage of input and output. The hardware subsystem is interfaced with the software to make the whole system automatic. The purpose of this paper is to automate apple classification. Presently, ANN is used in a wide range of classification applications. We have trained a back-propagation neural network to classify apple. Two sets of variables are used for the training purpose. First set is the independent variable, which is the surface level apple quality parameter. Second set is the dependent variable, which is the quality of the apple. The results of ANN model are discussed; however, the modeling results showed that there is an excellent agreement between the experimental data and predicted values, with a high determination coefficient, very good performance, fewer parameters, shorter calculation time and lower prediction error. The classification accuracy achieved is high, showing that a neural network is capable of making such classification. A low level of errors in classification confirmed that the neural network models are an effective instrument for apple classification. This model might be an alternative method for assessing the quality of apple and provide consumers with a safer food supply. © 2013, Springer-Verlag London.

Context: Senecio rufinervis D.C (Asteraceae) is a tall aromatic herb, commonly found in Uttarakhand, India. No investigations on the biological activity of this plant have been published so far. Hence, this plant species became a subject of our scientific interest. Objective: The aim of the study was to investigate the chemical composition and analgesic activity of Senecio rufinervis essential oil in mice using both thermal and chemical models of pain. Materials and methods: Essential oil from dried leaves of Senecio rufinervis was extracted by steam distillation and then subjected to GC-MS analysis. Varying doses of essential oil were given to mice, 30min prior to the induction of abdominal constrictions and determination of mean reaction time in hot-plate maintained at 55° ± 0.5°C. Results: The main component detected in the essential oil of Senecio rufinervis was germacrene D (40.19%) followed by β-pinene (12.23%), β-caryophyllene (6.21%) and β-longipinene (4.15%). Essential oil exhibited significant and dose-dependent analgesic activity against acetic acid-induced writhing in mice. The percentage inhibition in number of writhes produced by 25, 50 and 75mg/kg doses was, respectively, 69, 80 and 85%. The oil, at doses 50 and 75mg/kg, significantly increased the mean latency in the hot-plate after 15 and 30min of drug administration as compared to the control group. Discussion and conclusion: The results depicted both central and peripheral analgesic activity of S. rufinervis essential oil which was attributed to the presence of terpenes. © 2010 Informa Healthcare USA, Inc.
