Among 100 species of Swertia reported from the world, Nepal harbors 30 species along with four varieties. In Nepal, species of Swertia are highly exploited as raw materials for different traditional medicines. Among them, S. chirayita, a vulnerable species, has been considered to be superior in medicine and trade. One of the main issues in its trade is adulteration with other species which are considered to be inferior in medicinal quality. Species which are mixed with S. chirayita are S. angustifolia, S. ciliata, S. dilatata, S. paniculata, S. racemosa, etc. There is a need for the selection of most important morphological characteristics for instant identification of different species of Swertia to check illegal trade as well as adulteration. This paper aims to provide the most important identifying characters of eight species of Swertia traded from Nepal on the basis of their morphological studies. Color of the petal, number of floral parts (tetramerous vs. pentamerous) and number of glands in petal are the key characters for the identification of the species. Key-words: adulteration; medicinal plant; morphological characters.DOI: 10.3126/botor.v6i0.2906 Botanica Orientalis - Journal of Plant Science (2009) 6: 18-24

Amylase is an amylolytic enzyme used in food industry which is generally produced by Aspergillus spp. under solid state fermentation. The present study is concerned with the isolation, screening and selection of suitable strains of Aspergillus spp. and optimization of cultural conditions for the biosynthesis of amylase. Rice and wheat brans were used as substrates which are readily available inexpensive raw materials for amylase production. From 85 samples of rice and wheat grains, 55 colonies obtained on potato dextrose agar (PDA) were suspected to be Aspergillus oryzae and only 35 colonies possessed the morphological characteristics similar to that of A. oryzae indicating the isolates were most likely the strains of A. oryzae. Of all the fungal isolates of Aspergillus spps., Asp.31 gave maximum production of amylase (720.782 IUgds-1) in solid state fermentation media. This strain was selected as a parental strain for optimization for cultural conditions. The obtained data were analyzed using SPSS- 11.5 program. Of all the substrates (rice bran, wheat bran and their mixture), rice bran was the best for producing amylase of highest activity 611.614 IUgds-1.The highest enzyme activity of 698.749 IUgds-1 was observed at 50% initial moisture level of the substrate. The optimum temperature was 25°C for producing the crude amylase enzyme with amylase activity of 577.757 IUgds-1.

Rattan is a potential non-timber forest product. It grows in almost all parts of Indonesia, and has been widely used and traded. Indonesia as the largest rattan producer in the world supplies about 85% of world rattan needs. Bukit Lubuk Pekak Forest is part of the Production Forest Management Unit (KPHP) area, Merangin District, Jambi Province. The threat form rattan exploitation is increasing, especially in the Bukit Lubuk Pekak. Therefore, it is necessary to conduct study on the potency of rattan in that area for future conservation efforts. This study aimed to investigate rattan species in Bukit Lubuk Pekak forest, Merangin District, Jambi Province. Information of the potency of rattan is essential to support rattan industries. To complete data of rattan potency from Sumatra, an exploration in this area was carried out in July 2016 in Bukit Lubuk Pekak Forest. The study was conducted by purpossive sampling. Identification on morphological characteristics of rattan were performed on all  parts of plants including fruits and seeds (if available). The results showed that there were four rattan genus in Bukit Lubuk Pekak Forest: Calamus, Daemonorops, Korthalsia, and Plectocomiopsis. They consisted of nine species, namely Calamus caesius, C. exillis, C. insignis var. longispinosus, C. laevigatus, C. tumidus, Daemonorops micracantha, D. didymophylla, Korthalsia flagellaris, and Plectocomiopsis geminiflora. Among the nine species, two species that is Calamus caesius and Daemonorops didymophylla have been cultivated for industry raw materials and drug, respectively.

Herbs are an effective source of Ayurvedic medicine and other traditional medicines as well as modern medicine. Faced with the challenges of modern medicine, the world is shifting toward Ayurvedic theories of health management. In the treatment of the disease, the use of drugs is not limited. This increases the demand for raw materials exponentially. However, production growth is still linear. Rapid depletion of resources creates major problems. To fill the deficit, advances in adulteration and substitution are becoming more prevalent. This adulteration and substitution are a burning problem in an industry that threatens the integrity of Ayurvedic system of medicine. Imprecise knowledge, misidentification, deforestation, and personal gain have led to adulteration. Therefore, an understanding of all ways of adulteration and substitutions is needed to amend this illegal act and maximize consumer safety. This article focuses on adulteration, its types and various methods of adulteration, as well as the concept of substitution, reasoning, and its types. Attempts have also been made to differentiate these two related terms.

The therapeutic use of medicinal plants gained considerable momentum in the world during the past few decades. Traditional medicines, which are mostly based on the herbal raw materials growing in their respective regions, were used by over 70 percent of the world population as per WHO. The reason for their popularity was due to non-availability of modern medicines in the rural areas and also due to the unaffordability of modern medicines due to their high cost. Quality control of medicinal plants for use in these Traditional medicines has always been a challenge for the scientists working in this field. In our country, with the awareness growing among the people about the safety of Ayurvedic and Herbal medicines / cosmetics, the quality control testing of both raw herbal ingredients and finished formulations was seriously undertaken both by the academic / research institutions and the herbal drug manufacturers.

A controversial topic in the study of structure-property relationships of toughened polymer systems is the internal cavitation of toughener particles resulting from damage on impact or tensile deformation.Detailed observations of the influence of morphological characteristics such as particle size distribution on deformation mechanisms such as shear yield and cavitation could provide valuable guidance for selection of processing conditions, but TEM observation of damaged zones presents some experimental difficulties.Previously published TEM images of impact fractured toughened nylon show holes but contrast between matrix and toughener is lacking; other systems investigated have clearly shown cavitated impact modifier particles. In rubber toughened nylon, the physical characteristics of cavitated material differ from undamaged material to the extent that sectioning of heavily damaged regions by cryoultramicrotomy with a diamond knife results in sections of greater than optimum thickness (Figure 1). The detailed morphology is obscured despite selective staining of the rubber phase using the ruthenium trichloride route to ruthenium tetroxide.

Ben Jonson's early plays show a marked interest in prose as a counterpoint to the blank verse norm of the Renaissance stage. This essay presents a digital analysis of Jonson's early mixed-mode plays and his two later full-prose comedies. It examines this selection of the Jonsonian corpus using DocuScope, a piece of software that catalogs sentence-level features of texts according to a series of rhetorical categories, highlighting the distinctive linguistic patterns associated with Jonson's verse and prose. Verse tends to employ abstract, morally and emotionally charged language, while prose is more often characterized by expressions that are socially explicit, interrogative, and interactive. In the satirical economy of these plays, Jonson's characters usually adopt verse when they articulate censorious judgements, descending into prose when they wade into the intractable banter of the vicious world. Surprisingly, the prosaic signature that Jonson fashioned in his earlier drama persisted in the two later full-prose comedies. The essay presents readings of Every Man Out of his Humour and Bartholomew Fair, illustrating how the tension between verse and prose that motivated the satirical dynamics of the mixed-mode plays was released in the full-prose comedies. Jonson's final experiments with theatrical prose dramatize the exhaustion of the satirical impulse by submerging his characters almost entirely in the prosaic world of interactive engagement.

The author of the article discloses the prospects of development of the world feed production for aquaculture based on the analysis of key innovative technological and market trends. The author specifies that shortage, high cost, low ecological compatibility of traditional raw materials - fish flour - are among major limiting factors in the development of production of feeds for aquaculture. This fact, in turn, limits sustainable development of aquaculture both in Russia, and in the world in general. The article presents the overview of a current status of the world industry of feed production in aquaculture, where the regional situation is studied, as well. For the first time, there is given the outlook of innovative technologies in feed production based on the alternative sources of protein (on the example of projects of leading aquabiotechnological companies) which will determine industry’s objectives for the mid-term perspective.
