Title: Total flavonoid content and essential oil composition of Chaenomeles japonica (Thunb.) Lindl. ex Spach from North of Iran Authors: Hafez-Taghva, Pardis; Zamzad, Mina; Khalafi, Lida Abstract: Essential oil of the fruits of Chaenomeles japonica (Thunb.) Lindl. ex Spach was obtained by hydro distillation and analyzed by GC and GC-MS. Thirty five components representing 94.6 % of total were identified. The oil was rich in monoterpenes (88.3 %) and the main components were: carvacrol (62.6 %), limonene (8.0 %), p-cymene (4.9 %) and γ-terpinene (3.2 %). Quantitative assessment of flavonoids was conducted by aluminum chloride colorimetric method in terms of quercetin equivalent in various extracts of C. japonica fruits. After one week duration of extraction, the highest amount of flavonoid content (1.316 mg/g) was observed in chloroform extract. Page(s): 90-92

Title: Indigenous knowledge in utilization of wetland plants of Bhadrak district, Odisha, India Authors: Mishra, N; Panda, T; Pradhan, B K; Rout, S D; Mohanty, R B; Kishor, A; Singh, R R Abstract: The objective of the study was to determine the utilization of wetland plant resources for livelihood in Bhadrak district of Odisha, India. Information was gathered from 73 informants of various ages in different villages of the district by using participant observation, open-ended conversations and semi-structured questionnaires. A total of 42 wetland plant species, belonging to 36 genera and 27 families were found to have been used traditionally for edible purposes. The dominant families were Araceae, Nymphyaceae and Poaceae. The most frequently used plant species were Amorphophallus paeoniifolius Dennst. (Nicolson), Colocasia esculenta (L.) Schott., Ipomoea aquatica Forssk., Marsilea minuta L. and Trapa natans L. Proper documentation of traditional knowledge related to these plants and identification of potential species for prioritization of conservation through sustainable management is essential for socioeconomic development of the rural people.

2016-07-20T06:11:42Z

Title: Wild edible plants used by Konyak tribe in Mon district of Nagaland: Survey and inventorisation Authors: Pradheep, K; Soyimchiten; Pandey, Anjula; Bhatt, K C Abstract: This paper deals with 41 species of wild edible plants (WEPs) used by Konyak tribe in Mon district of Nagaland, recorded in two survey-cum-exploration trips undertaken during 2013 and 2014. The scientific and vernacular names of the plants, trends in domestication, period of availability, part(s) used and related notes are provided. Investigation for ethnobotanical studies and nutritive analysis has been emphasised. Fifteen WEPs were prioritised for germplasm collection and conservation. Page(s): 74-81

Standardization of eco-friendly technique for extraction of pectin from apple pomace

2016-07-20T06:17:19Z

Title: Standardization of eco-friendly technique for extraction of pectin from apple pomace Authors: Chandel, Vinay; Vaidya, Devina; Kaushal, Manisha; Gupta, Anil; Verma, Anil Kumar Abstract: Apple pomace, an industrial by-product generated from apple juice processing industries, is a good source of pectin. The method for pectin extraction has been standardized by autoclaving apple pomace flour for time intervals of 15, 30, 45 and 60 min at 121 °C. The extraction of pectin by using autoclave at 121°C for 60 min followed by precipitation with 95 % ethanol was found optimum with pectin yield of 13.01 % on dry weight basis and anhydrogalacturonic acid content of 43.21 %. The pectin extracted by using eco-friendly method is characterized by equivalent weight (942.04), methoxyl content (4.32 %), anhydrogalacturonic acid (43.21 %) and degree of esterification (56.76 %). However, autoclaving at 121 °C for 45 min also resulted in 12.97 % pectin, but on the basis of anhydrogalacturonic acid (%) contents, the autoclaving of pomace for 60 min was optimized. The standardized method can be used to replace the chemical extraction procedure for commercial extraction of pectin from apple pomace. Page(s): 69-73
