Title: Quality characteristics of Ohmic heated Aonla (Emblica officinalis Gaertn.) pulp Authors: Singh, A; Santosh, S; Kulshrestha, M; Chand, Khan; Lohani, UC; Shahi, NC Abstract: Present investigation deals with quality characteristics of aonla pulp subjected to ohmic heating at 11, 13, 15, 17 v/cm voltage gradients. The time and temperature were the process variables which were kept fixed on the basis of preliminary experiments. The product characteristics were evaluated for vitamin C, tannin content, titrable acidity, colour and microbial counts. Results indicated that all the quality parameters were influenced by treatment and KMS addition significantly. Per cent loss for all quality parameter was found to be least in aonla pulp ohmically treated at 17V/cm voltage gradient followed by 15, 13 and 11V/cm while the losses were maximum in conventionally prepared aonla pulp. Ohmically heated aonla pulp at 90°C for 1 minute was observed to be sufficient for safe storage of aonla pulp with little quality losses. In terms of quality, ohmically treated aonla pulp was found to be superior than conventionally prepared one. The quality losses in terms of vitamin C, tannin, titrable acidity and colour lightness were positively correlated to each other. Within the experimental range investigated in this study, aonla pulp ohmically heated at 17V/cm voltage gradients was found to be best in terms of all the quality parameters. Page(s): 670-676

Development of quality control markers for Ulmus wallichiana Planchon: An Indian traditional plant for osteogenic activity

Title: Development of quality control markers for Ulmus wallichiana Planchon: An Indian traditional plant for osteogenic activity Authors: Arya, K R; Khatoon, Sayyada; Kumar, Brijesh Abstract: Ulmus wallichiana Planchon, is an Indian folk traditional plant used for the treatment of fractured bones in folklore tradition of Uttarakhand Himalaya, India. During chemical investigations, three major compounds, Ulmoside A & B, and Naringenin-6-C-β-D glucopyranosideis for osteogenic activity have been isolated from bark of this plant species. This paper presents macro and microscopic study, physicochemical parameters and chemo-profiling of stem bark of U. wallichiana through Q TOF HRMS for development of quality control markers and identification of crude samples. Transverse section (TS) stem bark and powder microscopy shows crushed rhytidoma consisting plenty of mucilaginous canals followed by crushed cork, cells of the cork filled with dark brown content. Whereas, authenticity and quality of raw materials can be determinate with exact calculated mass value of marker compounds for osteogenic activity at 467, 451 and 435 using Q TOF HRMS technique. Ursolic acid, β-sitosterol and lupeol at R_f value 0.25, 0.36 and 0.44 has also identified as HPTLC marker for identification and authentication of crude drug samples of stem bark of U. wallichiana.

Spider web ointment: A traditional based approach in Cutaneous wound healing

Tue, 01 Oct 2013 00:00:00 GMT

Title: Spider web ointment: A traditional based approach in Cutaneous wound healing Authors: Kumari, Preeti; Chahar, MK; Veerapur, VP; Spandana, G; Thippeswamy, BS; Badami, S Abstract: Spider web is being used in India and other countries to promote wound healing. Its ointment at 2.5 and 5% w/w concentrations was tested for wound healing activity in excision and incision wound models in rats. A significant reduction in the area of excision wound was observed for both the treatments when compared to normal healing and control ointment treatments. The period of epithelization for spider web treatments was much lower than the standard povidone iodine ointment and significant when compared to normal and control ointment treatments. In the linear incision wound model, spider web ointment at 2.5% w/w showed 30.65% increase in the tensile strength compared to normal healing. The histological evaluation revealed that the spider web ointment lowers scores in terms of scab, ulcus, polymorphonuclear cells and high scores of re-epithelization and neovascularization when compared to normal healing group. Both the concentration of spider web ointment (2.5% and 5% w/w) exhibited similar wound healing activity. Therefore, the optimum effective dose of spider web ointment is 2.5% w/w concentration. The wound healing activity may be due to increase in collagen synthesis and probably due to the presence of proteins in the web. The present study provides a scientific base for the traditional use of spider web for wound healing. Page(s): 657-663

Dye plants: Natural resources from traditional botanical knowledge of Sardinia Island, Italy

Title: Dye plants: Natural resources from traditional botanical knowledge of Sardinia Island, Italy Authors: Maxia, Andrea; Meli, Francesca; Gaviano, Carla; Picciau, Rosangela; Martis, Bruno De; Kasture, Sanjay; Kasture, Veena Abstract: Now a days the use of wild plant species for colouring textile articles is very modest in Europe, mainly because of the incessant production of synthetic dyes, which are economic and easy to find. The tradition of using dye plants still persists in the Mediterranean region, but is not widely studied. In this paper, the authors, for the first time, study the natural colours and wild species used in the popular Sardinian tradition. They try to bring order and Scientific rigor of an important topic, with an emphasis on the economic value of knowledge passed down orally from generation to generation. Page(s): 651-656
