Prospects for Chinese Botanical GardensFoundation items: Supported by Chinese Biodiversity Conservation and Green Development Foundation

In China, a new period of development in the first decade of the 21st Century with rapid urbanization, was marked by investment in construction of over five billion yuan. At this time of rapid change it is important for botanical gardens to follow three principles, “scientific contents, artistic appearance, and cultural display”, so as not to become public parks. The scientific component is important. It is not necessary for every botanical garden to do basic botanical research but they should all be involved in plant conservation issues, especially ex-situ conservation and keep accurate data on their living collections. Although a heavy responsibility this documentation is the foundation and the bottom line of scientific meaning for a botanical garden. Economic plant research, exploring new resources, was a major contribution of botanical gardens historically and remains important for sustainable cities and the national economy of China. Education and ecotourism are important ways for botanical gardens to serve the public displaying the interesting plant collections to enhance relaxation and well-being. It is reasonable to make income through all activities in a botanical garden but this should not be the major goal. It should be understood botanical gardens are comprehensive and multi-functional bodies determined by science, the arts and culture.     

Plants with Histories: The Changing Ethnobotany of Iquito Speakers of the Peruvian Amazon

Plants with Histories: The Changing Ethnobotany of Iquito Speakers of the Peruvian Amazon. This paper describes the first ethnobotanical study carried out with speakers of Iquito, a critically endangered language of northeastern Peru. The work examines significant changes the pharmacopoeia has undergone, developing a new measure, the Index of Plant Novelty (IPN) that combines oral history, linguistic, comparative ethnobotanical, and botanical data. Research was carried out in 2009 and 2010, with structured interviews and collection of 87 botanical voucher specimens in 39 botanical families. The study results suggest that no one single factor can fully explain the patterns of borrowing in the pharmacopoeia of San Antonio, although data show some support for previously proposed hypotheses that such borrowing fills gaps in the pharmacopoeia or that edible and ornamental plants are often adopted for medicinal use. However, this process must also be understood within the context of colonization by mestizo settlers, which has given higher prestige to uses and species from outside. A comparison between oral history data and the linguistic and comparative data suggests that the Iquito informants interviewed have underestimated the extent to which their current pharmacopoeia has been borrowed.     

Chemometric Analysis for Identification of Botanical Raw Materials for Pharmaceutical Use: A Case Study Using Panax notoginseng

The overall control of the quality of botanical drugs starts from the botanical raw material, continues through preparation of the botanical drug substance and culminates with the botanical drug product. Chromatographic and spectroscopic fingerprinting has been widely used as a tool for the quality control of herbal/botanical medicines. However, discussions are still on-going on whether a single technique provides adequate information to control the quality of botanical drugs. In this study, high performance liquid chromatography (HPLC), ultra performance liquid chromatography (UPLC), capillary electrophoresis (CE) and near infrared spectroscopy (NIR) were used to generate fingerprints of different plant parts of Panax notoginseng. The power of these chromatographic and spectroscopic techniques to evaluate the identity of botanical raw materials were further compared and investigated in light of the capability to distinguishing different parts of Panax notoginseng. Principal component analysis (PCA) and clustering results showed that samples were classified better when UPLC- and HPLC-based fingerprints were employed, which suggested that UPLC- and HPLC-based fingerprinting are superior to CE- and NIR-based fingerprinting. The UPLC- and HPLC- based fingerprinting with PCA were able to correctly distinguish between samples sourced from rhizomes and main root. Using chemometrics and its ability to distinguish between different plant parts could be a powerful tool to help assure the identity and quality of the botanical raw materials and to support the safety and efficacy of the botanical drug products.     

Behaviour of granular starches in low-pressure glow plasma

Granular starches of nine botanical origins were exposed to low-pressure glow plasma generated in the air from either a high voltage DC supply or an AC inductor. Experiments with low energy air-plasma (10⁻² Torr) and starches provided insight into some details of their surface structure. Starches were partly oxidized to carboxylic starches and partly depolymerized. Their affinity to plasma depended on their botanical origin. The structure of starch granules seemed to be a crucial factor, which determined the behaviour of starches in plasma. Lipids and/or proteins stabilized polysaccharides to plasma being preferentially decomposed.     

Factors and “Toolkits”: Evaluating Multivariate Analyses in Archaeology

Abstract

This paper explores the potential contribution that the use of simulated data can make in evaluating applications of multivariate analytic technqiues. Production of simulated data and evaluation of analytic techniques is shown to requiredevelopment of archaeological theory. Several models of cultural formation processes, an undeveloped branch of archaeological theory, are presented which indicate that under certain conditions factor analysis may be a useful technique for isolating sets of artifacts used in the same activity area. One of these models is positively tested on simulated secondary refuse data. The results demonstrate the utility of coupling discussions of analytic techniques with explicit archaeological theory and testing one’s models on simulated data.     

Batch-to-Batch Quality Consistency Evaluation of Botanical Drug Products Using Multivariate Statistical Analysis of the Chromatographic Fingerprint

Botanical drug products have batch-to-batch quality variability due to botanical raw materials and the current manufacturing process. The rational evaluation and control of product quality consistency are essential to ensure the efficacy and safety. Chromatographic fingerprinting is an important and widely used tool to characterize the chemical composition of botanical drug products. Multivariate statistical analysis has showed its efficacy and applicability in the quality evaluation of many kinds of industrial products. In this paper, the combined use of multivariate statistical analysis and chromatographic fingerprinting is presented here to evaluate batch-to-batch quality consistency of botanical drug products. A typical botanical drug product in China, Shenmai injection, was selected as the example to demonstrate the feasibility of this approach. The high-performance liquid chromatographic fingerprint data of historical batches were collected from a traditional Chinese medicine manufacturing factory. Characteristic peaks were weighted by their variability among production batches. A principal component analysis model was established after outliers were modified or removed. Multivariate (Hotelling T ² and DModX) control charts were finally successfully applied to evaluate the quality consistency. The results suggest useful applications for a combination of multivariate statistical analysis with chromatographic fingerprinting in batch-to-batch quality consistency evaluation for the manufacture of botanical drug products.     

Dr. Auzoux's botanical teaching models and medical education at the universities of Glasgow and Aberdeen

In the 1860s, Dr. Louis Thomas Jérôme Auzoux introduced a set of papier-mâché teaching models intended for use in the botanical classroom. These botanical models quickly made their way into the educational curricula of institutions around the world. Within these institutions, Auzoux’s models were principally used to fulfil educational goals, but their incorporation into diverse curricula also suggests they were used to implement agendas beyond botanical instruction. This essay examines the various uses and meanings of Dr. Auzoux’s botanical teaching models at the universities of Glasgow and Aberdeen in the nineteenth century. The two main conclusions of this analysis are: (1) investing in prestigious scientific collections was a way for these universities to attract fee-paying students so that better medical accommodation could be provided and (2) models were used to transmit different kinds of botanical knowledge at both universities. The style of botany at the University of Glasgow was offensive and the department there actively embraced and incorporated ideas of the emerging new botany. At Aberdeen, the style of botany was defensive and there was some hesitancy when confronting new botanical ideas.

Bioinformatics analysis to identify possible mechanisms of action of curcumin against tea geometrid

Curcumin, a bright yellow chemical produced from curcuma longa root, is an effective insecticide, but how it works against pests such as tea geometrid (E. obliqua) is unclear. Here possible protein targets of curcumin were identified in the PubChem database, and possible targets in tea geometrid were identified using RNA sequencing; then, both sets of candidate targets were subjected to Ingenuity Pathway Analysis. The results predict that curcumin may affect several signalling proteins in tea geometrid, including TOP2B, TP53, MDM4, YWHAB, TOP2A, MDM2 and EP300; these proteins are involved in key biological processes including the cell cycle; DNA replication, recombination and repair; cellular assembly and organization; and cell death and survival. These results illustrate the power of integrative informatics and chemical fragment analysis for focusing mechanistic studies of botanical insecticides.

Effect of circumferential heterogeneity of wood maturation strain, modulus of elasticity and radial growth on the regulation of stem orientation in trees

Active mechanisms of re-orientation are necessary to maintain the verticality of tree stems. They are achieved through the production of reaction wood, associated with circumferential variations of three factors related to cambial activity: maturation strain, longitudinal modulus of elasticity (MOE) and eccentric growth. These factors were measured on 17 mature trees from different botanical families and geographical locations. Various patterns of circumferential variation of these factors were identified. A biomechanical analysis based on beam theory was performed to quantify the individual impact of each factor. The main factor of re-orientation is the circumferential variation of maturation strains. However, this factor alone explains only 57% of the re-orientations. Other factors also have an effect through their interaction with maturation strains. Eccentric growth is generally associated with heterogeneity of maturation strains, and has an important complementary role, by increasing the width of wood with high maturation strain. Without this factor, the efficiency of re-orientations would be reduced by 31% for angiosperms and 26% for gymnosperms. In the case of angiosperms, MOE is often larger in tension wood than in normal wood. Without these variations, the efficiency of re-orientations would be reduced by 13%. In the case of gymnosperm trees, MOE of compression wood is lower than that of normal wood, so that re-orientation efficiency would be increased by 24% without this factor of variations.

Plant collecting along the lower Orinoco,Venezuela: H. H. Rusby and R. W. Squires (1896)

The plant collecting trip by H. H. Rusby and R. W. Squires in early 1896 to the lower Río Orinoco, Venezuela, was sponsored by The Orinoco Company Limited, which was promoted by many residents of Faribault, Rice Co., Minnesota, U.S.A. In February 1896, the company formed an exploring party in order to map a large concession of approximately 10,000,000 acres that they had received from the Venezuelan government and to prospect the mineral deposits, study the vegetation, and ascertain the conditions affecting colonization of the concession. The botanical work was entrusted to Rusby, who with the assistance of Squires and an unnamed laborer from Trinidad, collected almost 500 numbers of vascular plants in sets as large as thirty-two. Rusby indicated that he spent only 51 days in the field and lost a week of that time to an accident that befell the explorers. He was less constrained than the Minnesotans (who were promoting development), and he wrote that botanical exploration was hampered also by the inundation of the forests and savannahs with each tide, the lack of trails, and the large numbers of annoying insects and poisonous snakes. An annotated catalog of 43 new taxa of vascular plants based on Rusby and Squires's collection is provided. Lectotypes are designated forTachigalia rusbyi Harms (Fabaceae),Cupania semidentata Radlk. (Sapindaceae), andSolanum sacupanense Rusby (Solanaceae). A gazetteer of the localities cited in Rusby's field book and in publications pertaining to the Orinoco trip is appended.
