The present study deals with the macroscopic and microscopic studies of Manilkara hexandra (Roxb.) Dubard leaf is commonly known as Rayan, traditionally used as antioxidant, antimicrobial, immune stimulant, anti ulcer, anti bacterial and antidiabetic. In the present work fresh leaf was studied for pharmaconostic evaluations, including examination of morphological and microscopic characters, physicochemical parameter, phytochemical test, extractive values and fluorescence study. The anatomy of the leaf was studied by taking transverse section which showed anomocytic stomata, unicellular trichomes, spongy parenchyma etc. Powder microscopic examination showed presence of pericyclic fibers, spiral xylem vessels, phloem fiber and stomata. Physicochemical parameters and fluorescence analysis of the powder and extract were also carried out. The phytochemical test revealed the presence of alkaloids, glycosides, tannins, flavonoids and saponin in methanol extract. The present investigation on Manilkara hexandra leaf might be useful to supplement information in regard to its identification parameters. Such studies are important in the way of acceptability of herbal drugs in present scenario of lacking regulatory laws to control quality of herbal drugs.

  • Chapter 3 Protection from Wind and Salt Spray
    CHAPTER 3 PROTECTION FROM WIND AND SALT SPRAY Thematic paper: Protective functions of coastal forests and trees against wind and salt spray Eugene S. Takle, T.-C. Chen and Xiaoqing Wu1 This paper provides an overview of the hazard potential presented by wind and salt spray to human settlements in coastal areas of Southeast Asia. Damage to infrastructure (such as buildings, dams, bridges and dykes) and degradation of natural systems in Southeast Asia and India due to wind and salt spray are closely linked to climatological conditions that lead to high wind in the region (Section 1.1). The mechanisms for generation of salt spray and their relation to windspeed are discussed in Section 1.3. Introducing shelterbelts and coastal forests is proposed as an environmentally attractive method for suppressing damage due to wind and sea spray. The properties of shelterbelts that define their effectiveness for reducing wind and capturing sea salt are described in Section 2 and the development of guidelines for their re-establishment in coastal areas is addressed in Section 3. There is a brief discussion on economics and social aspects of establishing coastal forests in Section 4, and Section 5 offers concluding remarks. 1 Wind and salt spray damage in Asia Section 1 gives an overview of wind and salt spray damage potential for Southeast Asia. Actual records or maps of past damage to human assets in the region are neither comprehensive nor widely available, particularly in the context of salt spray damage. Available data for assessing wind and salt spray damage potential in Southeast Asia are perhaps a useful surrogate and arguably more relevant for policy-making, as actual damage maps would be highly dependent on the value of coastal human assets exposed to damaging conditions.

Smedmark ¤, Ulf Swenson, Arne A. Anderberg Department of Phanerogamic Botany, Swedish Museum of Natural History, P.O. Box 50007, SE-104 05 Stockholm, Sweden Received 9 September 2005; revised 4 January 2006; accepted 12 January 2006 Available online 21 February 2006 Abstract We used Bayesian phylogenetic analysis of 5 kb of chloroplast DNA data from 68 Sapotaceae species to clarify phylogenetic relation- ships within Sapotoideae, one of the two major clades within Sapotaceae. Variation in substitution rates through time was shown to be a very important aspect of molecular evolution for this data set. Relative rates tests indicated that changes in overall rate have taken place in several lineages during the history of the group and Bayes factors strongly supported a covarion model, which allows the rate of a site to vary over time, over commonly used models that only allow rates to vary across sites. Rate variation over time was actually found to be a more important model component than rate variation across sites. The covarion model was originally developed for coding gene sequences and has so far only been tested for this type of data. The fact that it performed so well with the present data set, consisting mainly of data from noncoding spacer regions, suggests that it deserves a wider consideration in model based phylogenetic inference. Repeatability of phylogenetic results was very diYcult to obtain with the more parameter rich models, and analyses with identical settings often supported diVerent topologies.

  • Manilkara Hexandra (Roxb.) Dubard] Fruit
    Original article Physiological changes in relation to growth and ripening of khirni [Manilkara hexandra (Roxb.) Dubard] fruit Prakash Ramanbhai PATEL, Tadapaneni Venkata RAMANA RAO* Dep. Biosciences, Sardar Patel Physiological changes in relation to growth and ripening of khirni [Manilkara Univ., Vallabh Vidyanagar, hexandra (Roxb.) Dubard] fruit. Gujarat – 388120, India Abstract –– Introduction. Fruit ripening is the process resulting in changes in color, taste and [email protected] texture, which make the fruit acceptable for consumption. Since a wide spectrum of physiolo- gical, biochemical and organoleptic changes are involved in the development of a soft, edible, ripe fruit, we studied theses changes in an underutilized fruit, khirni [Manilkara hexandra (Roxb.) Dubard]. Materials and methods. The changes in biochemical composition, which includes chlorophylls, carotenoids, anthocyanins, sugars, starch, free amino acids, phenols and proteins, and the specific activity of enzymes such as amylase, invertase, catalase, peroxidase, pectinmethylesterase, polygalacturanase and cellulase were analyzed in the fruit of Manilkara hexandra at five sequential developmental stages (young, premature, mature, preripened and ripened fruit stages). Results and discussion. The pulp of khirni fruit tastes sour during its growth period, but turns sweet when it ripens. A decreasing trend in chlorophylls occurs simul- taneously with an increase in the quantity of total carotenoids and anthocyanins. Further, an increase in the quantity of sugars, proteins and phenols occurs towards the ripened stage, but starch and total free amino acids show a decrease in their quantities. Also, khirni fruit exhibits climacteric behavior with its increased rate of respiration and ethylene production. The moderate to significant changes in the activity of enzymes such as amylase, invertase, catalase and peroxi- dase involved in a number of catabolic and anabolic reactions indicate that these enzymes also have an active role in the process of khirni fruit growth and ripening.
