fabrication performance evaluation and optimization of sal Shorea Robusta seed decorticator
Journal of Food Process Engineering, 2017Co-Authors: Shashi C Kumar, Rama Chandra Pradhan, Sabyasachi MishraAbstract:Sal (Shorea Robusta) seed is a nontimber forest product, mainly processed for its oil. This oil is used in various food and nonfood industries. Prior to extraction of oil, sal seeds are manually broken to obtain sal kernel. This traditional manual de-shelling process is very tedious, time consuming and unhygienic. Hence, in this research, a sal seed decorticator was designed, fabricated and its performance was evaluated. The performance parameters of the machine were tested with varying moisture content from 10.49% to 21.95% (d.b) and different concave clearance varying from 10 mm to 19 mm. The decorticating efficiency, machine efficiency, and kernel percentage were found to have a maximum value of 99.15 ± 0.04%, 93.62 ± 0.87%, and 62.71 ± 1.73%, respectively at 13.63% (d.b) moisture content and 13 mm concave clearance. Results were fitted in response surface methodology to optimize the parameters and to find the level of significance between the independent and dependent variables.

exploration of Shorea Robusta sal seeds kernels and its oil
Cogent food & agriculture, 2016Co-Authors: Shashi C Kumar, Rama Chandra Pradhan, Sabyasachi MishraAbstract:AbstractPhysical, mechanical, and chemical properties of Shorea Robusta seed with wing, seed without wing, and kernel were investigated in the present work. The physico-chemical composition of sal oil was also analyzed. The physico-mechanical properties and proximate composition of seed with wing, seed without wing, and kernel at three moisture contents of 9.50% (w.b), 9.54% (w.b), and 12.14% (w.b), respectively, were studied. The results show that the moisture content of the kernel was highest as compared to seed with wing and seed without wing. The sphericity of the kernel was closer to that of a sphere as compared to seed with wing and seed without wing. The hardness of the seed with wing (32.32, N/mm) and seed without wing (42.49, N/mm) was lower than the kernels (72.14, N/mm). The proximate composition such as moisture, protein, carbohydrates, oil, crude fiber, and ash content were also determined. The kernel (30.20%, w/w) contains higher oil percentage as compared to seed with wing and seed without ...

The kernel (30.20%, w/w) contains higher oil percentage as compared to seed with wing and seed without wing. The scientific data from this work are important for designing of equipment and processes for post-harvest value addition of sal seeds

Shorea Robusta (Dipterocarpaceae) seed and its oil as food
2015Co-Authors: C Shashi Kumar, Rama Chandra Pradhan, Payel Ghosh, Sandeep Singh Rana, Sabyasachi MishraAbstract:Shorea Robusta (Sal) belongs to the family of Dipterocarpaceae. Sal has an important role in the economics of central states of India (i.e. Orissa, Jharkhand and Madhya Pradesh). These states cover about 45 % of forest area. Sal is a deciduous tree that reaches up to 50 m height. Sal is famous for its seed and oil. Sal fruit pulp is edible; it contains sugar, gum, malic, citric and tartaric acids. Sal is a crucial plant for veterinary medicines (used as vaccine and medicine for respiratory diseases). Sal fruit content 66.4% of kernel and pod, reaming 33.6% is shell and calyx. Sal seeds are processed mainly for its fat or oil. It also has a leading role in food and cosmetic sectors. The extracted Sal oil is greenish brown colour and characteristic odour. The refined oil from Sal seed is used for cooking and substitutes for cocoa butter in chocolate manufacturing industries. It also used for the production of vanaspati, paints, pigments, lubricants, biogas and biodiesel. Besides, de-oiled cake also has a good export market for cattle, poultry and fish feed.

Triterpenoids from Shorea Robusta resin
Phytochemistry, 1997Co-Authors: Laxmi N. Misra, Ateeque AhmadAbstract:The resin of Shorea Robusta has yielded eight known triterpenoids of which five have been isolated for the first time. It has also afforded two new triterpenoids, namely 3,25-epoxy-1,2,3,11-tetrahydroxyurs-12-en-28-oic acid and 3,25-epoxy-1,2,3-trihydroxyurs-12-en-28-oic acid whose structures have been elucidated by spectroscopic methods and chemical transformations.

evaluation of the wound healing activity of Shorea Robusta an indian ethnomedicine and its isolated constituent s in topical formulation
Journal of Ethnopharmacology, 2013Co-Authors: Hemanta Mukherjee, Durbadal Ojha, Yogesh P Bharitkar, Soma Ghosh, S Mondal, Sudipta Kaity, Shanta Dutta, Amalesh Samanta, Tapan Kumar Chatterjee, Sekhar ChakrabartiAbstract:Abstract Ethnopharmacological relevance Different parts of Indian ethnomedicinal plant Shorea Robusta is traditionally used for several ailments including wounds and burn by different tribal groups, since ages. Here we have validated, for the first time, the effectiveness and the possible mechanism of action of young leaf extracts of Shorea Robusta, used by two distinct tribes of India, and its isolated compounds as a topical formulation in three wound models in rats. Materials and methods Bioactivity-guided study of the active extract resulted in the isolation of two known compounds. The prepared ointment containing extracts (2.5 and 5%, w/w), fractions (5% w/w) and isolated compounds (0.25% w/w) were evaluated on excision, incision and dead space wound models in rats by the rate of wound closure, period of epithelialisation, tensile strength, granulation tissue weight, hydroxyproline content and histopathology. Results The animals treated with the extracts and fractions (5%) showed significant reduction in wound area 96.55 and 96.41% with faster epithelialisation (17.50 and 17.86), while the isolated compounds bergenin and ursolic acid heal the wound faster, but complete epithelialisation with 100% wound contraction was evident with 5% povidone–iodine group on 18th post-wounding day. Moreover, the tensile strength of incision wound, granuloma tissue weight, and hydroxyproline content was significantly increased in both the extract and compound(s) treated animals. Furthermore, the tissue histology of animals treated with the isolated compound(s) showed complete epithelialisation with increased collagenation, similar to povidone–iodine group. Conclusion Thus, our results validated the traditional use of Shorea Robusta young leaves in wound management.
