<p>Rodent tuber (Typhonium flagelliforme Lodd.) is a plant from Araceae family. The plant has high medical potential as anti-cancer agent. The information regarding Indonesian rodent tuber’s genetic diversity is not available yet. Genetic information is very important for the development of rodent tuber as medicinal plant. In this research, genetic diversity and genetic distance of three Indonesian rodent tuber’s cultivars, from Bogor, Pekalongan, and Medan, were analyzed by using RAPD molecular markers. The data obtained was analyzed by NTsys software. Out of 16 primers used in the study, the 12 primers were found to be polymorphic. There were 83 bands of DNA obtained and 31 of them were polymorphic. Dendogram analysis of the three rodent tuber cultivars showed that these cultivars were clustered into two clusters. The first cluster consists of rodent tuber Bogor and Medan. The second cluster consists of rodent tuber Pekalongan. The coefficient of similarity ranged from 0.81 to 0.87. The highest coefficient of similarity was 0.87, which was detected between rodent tuber Pekalongan and Medan. The lowest coefficient of similarity was 0.81, which was detected between rodent tuber Bogor and Pekalongan. Among these three cultivars of rodent tuber, cultivar Bogor was exclusively different.</p><p><br /><strong>Keywords</strong>: Indonesia-rodent tuber, genetic diversity, RAPD-marker</p>

Microbiological Properties

Epidendrum mosenii is a Brazilian medicinal plant, traditionally used to treat infections and pains. This study reports on the chemical composition and microbiological properties of different parts and in different seasons of this plant. Results demonstrate that 4,3′,5′-trihydroxy-3-methoxy-dihydrostilbene (1), 4,5-dihydroxy-3,3-dimethoxy-dihydrostilbene (2) and pholidotin (3) were mainly present in the roots in all seasons, and the yield of mass extract increased their recovery in other parts, such as the stem and leaves for compounds (2) and (3), in summer and winter, respectively. The antifungal results indicate that compounds (1) and (2) have interesting activity against Cryptococcus neoformans, Microsporum gypseum, Trychophyton rubrum and Trychophyton mentagrophytes with MIC values between 62.5 and 125 μg/mL. Taken together, these results strongly suggest that the antifungal properties of E. mosenii are related, at least in part, to the presence of dihydrostilbenes 1 and 2, and this is useful for quality control of phytopreparations based on this plant, justifying the popular use of this plant to treat infections.

This is a review on the pharmacological properties and chemical composition of Icacina trichantha (Icacinaceae), a food and medicinal plant native to West Africa. The tuber is a good source of nutrients such as starch; it also exhibits a variety of pharmacological activities in animal models. Chemical analysis has revealed the presence of a series of unusual pimarane-type diterpenes.

Abstract After a brief introduction to the generic aspects of automation in analytical laboratories, the different approaches to quality in analytical chemistry are presented and discussed to establish the following different facets emerging from the combination of quality and automation: automated analytical control of quality of products and systems; quality control of automated chemical analysis; and improvement of capital (accuracy and representativeness), basic (sensitivity, precision, and selectivity), and complementary (rapidity, cost, and personnel factors) analytical features. Several examples are presented to demonstrate the importance of this marriage of convenience in present and future analytical chemistry.

Herbal Drug

The first step in quality control of herbal drugs is ensuring the correct identification of the plant intended for use. The required analytical procedures (macroscopic characterization of the entire or fragmentized material, microscopic characterization after pulverization of the plant material and chemical characterization), are usually described on quality monographs reported in authoritarian texts such as the European 6th Pharmacopoeia. Further information related to the name of the each herbal drug, the herbal drug definition, purity tests and assay are also provided.

Prior Analysis

Essential oil extracts from the leaves of two Lantana species ( L. radula Sw. and L. canescens Kunth), for which no prior analysis has been reported, were analyzed by GC-MS. This information was utilized to propose chemical markers for Lantana species so that identification between physically similar plant species can be achieved through chemical analysis. Results showed 33 constituents for L. canescens, among which β-caryophyllene (43.9%), β-cubebene (10.1%), elixene (8.6%), β-phellandrene (6.1%), α-caryophyllene (2.6%) and dehydro-aromadendrene (2.6%) were the principle components. L. radula revealed the presence of 21 compounds, the most abundant of which were β-cubebene (31.0%), β-caryophyllene (20.8%), elixene (10.0%), α-salinene (6.4%), β-phellandrene (6.1%), copaene (4.9%) cadinene (1.4%) and psi-limonene (1.4%). The high concentration of β-caryophyllene in the samples tested here and those in the literature make it a good candidate for a chemical marker for Lantana species, with β-cubebene, elixene and β-phellandrene following as minor compounds identified more sporadically in this genus. On the other hand, Lippia species, which are morphologically similar to those from the Lantana genus, would contain limonene, citral, carvacrol, β-myrcene, camphor and thymol as the main chemical markers. These chemical markers would be a powerful tool for maintaining quality control in the extraction of essential oils for use in medicinal applications, as well as in identification of plant specimens to a taxonomist.
