PHARMACOGNOSTICAL AND PHYTO-CHEMICAL EVALUATION OF PIPPALYADI YOGA: A POLYHERBAL FORMULATION
Pippalyadi Yoga is Churna Kalpana described by Acharya Chakrapani in Vandhyatva (infertility). Ovulatory dysfunction is the prime cause of Infertility among the world, Pippalyadi Yoga is useful in patients especially having Anovulation which is known as Abeejatva in Ayurveda. So a new pharmaceutical preparation Pippalyadi Yoga in the form of Churna (powder) was tried to standardize which is economical in terms of time and machinery usage. Pharmacognostical and phyto-chemical observations revealed the specific characters of all active constituents used in the preparation. The present work was carried out to standardize the finished product of Pippalyadi Yoga to confirm its identity, quality and purity. The presence of stone cells, oil globules, olio resin cells, parenchymatous cells, oval & beaker shaped starch grains, pollen grains were the characteristic features observed in the microscopy of the prepared drug. Phyto-chemical analysis showed Loss on drying 10.07 % w/w, ash value 6.55 %w/w, water soluble extract 14 % w/w, methanol soluble 13.40 % w/w, particle consistency above 60 mesh 4.10 % w/w, between 60-85 mesh 9.20 % w/w, between 85-120 mesh 13.30 % w/w & below 120 mesh 73.37 % w/w & pH 5.0.

Livelihood responses to Lantana camara invasion and biodiversity change in southern India: application of an asset function framework
Natural resources play key roles as assets in the livelihoods of rural communities. However, the benefits of these assets in livelihoods are frequently conceived narrowly as income generating or vulnerability reducing. We contend that they have other important roles to play in poverty reduction and livelihood change. In this paper we use a case study of two ethnic communities in a village in southern India to investigate livelihood responses to change in forest biodiversity through an examination of changes in attributes of natural assets resulting from the invasion of Lantana camara and wider socio-economic change. The invasion of forest by Lantana has contributed to changes in the attributes and functions of four key natural assets: forest grazing, bamboo for basketry, Phoenix loureie for brooms, and wild yams. We observe that differences in households’ and individuals’ ability to substitute important functions of lost or declining assets affect their ability to adapt to changes in resource availability and attributes. Analysing changes in asset attributes for different user groups allows the social effects of environmental change to be disaggregated
The use of focus group discussion methodology: Insights from two decades of application in conservation
This is the final version of the article. Available from Wiley via the DOI in this recordFocus group discussion is frequently used as a qualitative approach to gain an in-depth understanding of social issues. The method aims to obtain data from a purposely selected group of individuals rather than from a statistically representative sample of a broader population. Even though the application of this method in conservation research has been extensive, there are no critical assessment of the application of the technique. In addition, there are no readily available guidelines for conservation researchers. Here, we reviewed the applications of focus group discussion within biodiversity and conservation research between 1996 and April 2017. We begin with a brief explanation of the technique for first-time users. We then discuss in detail the empirical applications of this technique in conservation based on a structured literature review (using Scopus). The screening process resulted in 170 articles, the majority of which (67%, n = 114,) were published between 2011 and 2017. Rarely was the method used as a stand-alone technique. The number of participants per focus group (where reported) ranged from 3 to 21 participants with a median of 10 participants. There were seven (median) focus group meetings per study. Focus group discussion sessions lasted for 90 (median) minutes. Four main themes emerged from the review: understanding of people's perspectives regarding conservation (32%), followed by the assessment of conservation and livelihoods practices (21%), examination of challenges and impacts of resource management interventions (19%) and documenting the value of indigenous knowledge systems (16%). Most of the studies were in Africa (n = 76), followed by Asia (n = 44), and Europe (n = 30). We noted serious gaps in the reporting of the methodological details in the reviewed papers. More than half of the studies (n = 101) did not report the sample size and group size (n = 93), whereas 54 studies did not mention the number of focus group discussion sessions while reporting results. Rarely have the studies provided any information on the rationale for choosing the technique. We have provided guidelines to improve the standard of reporting and future application of the technique for conservation.N.T.O. was funded by Cambridge Overseas Trusts, The Wildlife Conservation Society, Wildlife Conservation Network and WildiZe Foundation.

Pharmacognostical and physicochemical analysis of Tamarindus indica Linn. stem
Tamarindus indica Linn. fruits (Chincha) are extensively used in culinary preparations in Indian civilization. Its vast medicinal uses are documented in Ayurvedic classics and it can be used singly or as a component of various formulations. Besides fruit, the Kasta (wood) of T. indica L. is also important and used to prepare Kshara (alkaline extract) an Ayurvedic dosage form. Pharmacognostical and physicochemical details of Chincha Kasta are not available in authentic literature including API (Ayurvedic Pharmacopoeia of India). The study is an attempt in this direction. T. indica L. stem with heartwood was selected and morphological, microscopic and physicochemical standardization characters along with TLC finger print, and fluorescence analysis were documented. Transverse section of stem showed important characters such as phelloderm, stone cells layer, fiber groups, calcium oxalate, crystal fibers, and tylosis in heartwood region. Four characteristic spots were observed under UV long wave, in thin layer chromatography with the solvent combination of toluene: ethyl acetate (8:2). The study can help correct identification and standardization of this plant material
Ajwain (Trachyspermum ammi L. Sprague) based intercropping for higher system productivity of semiarid tropics of Northern Karnataka
Field trials were executed at the University of Horticultural Sciences, Bagalkot, Karnataka during the kharif season of 2016 and 2017 to study the growth and productivity of ajwain and leafy vegetables under intercropping system and the cost economics of cropping systems in Northern Karnataka. The experiments were carried out with thirteen treatments comprising sole ajwain and sole crops of leafy vegetables (Fenugreek, Coriander, Dill and Amaranthus) and various combinations of ajwain+ leafy vegetables in 1:1 and 1:2 ratios adopting randomized complete block design with three replications. Results showed that the sole crop of ajwain exhibited superior growth and yield. However, in intercropping systems, the combination of ajwain and coriander at a 1:1 ratio demonstrated the highest growth and yield parameters. The sole crop of ajwain recorded the maximum plant height (84.64 and 84.55 cm), number of branches per plant (52.38 and 52.19), number of umbels per plant (166.54 and 164.93), number of umbellate per umbel (12.44 and 12.34), and seed yield (12.95, 12.88 q/ha during both years, respectively). This performance was comparable to intercropping with ajwain + coriander (1:1). Sole crops of fenugreek, coriander, dill, and amaranthus yielded higher fresh market yields compared to different intercropping systems. Notably, growing ajwain as an intercrop with coriander at a (1:1) resulted in a significantly higher land equivalent ratio (1.61) and a higher benefit-cost ratio (2.99), followed by ajwain + fenugreek (1:1) (2.98)
