TL;DR: Recent chemical work on various Chinese medicinal plants is reviewed, including Mussaenda pubescens (Rubiaceae), Isatis indigotica (Cruciferae), Euphorbia fischeriana, and E. ebracteolata (Euphorbiaceae), and Stemona species (Stemonaceae).
Abstract: China has accumulated a rich body of empirical knowledge of the use of medicinal plants for the treatment of various diseases throughout its long history. Chemical studies on Chinese medicinal plants provide a valuable material base for the discovery and development of new drugs of natural origin. In this article recent chemical work on various Chinese medicinal plants is reviewed, including Mussaenda pubescens (Rubiaceae), Isatis indigotica (Cruciferae), Euphorbia fischeriana, and E. ebracteolata (Euphorbiaceae), and Stemona species (Stemonaceae). The structural diversity of the medicinal chemical constituents of the above plants is discussed.

TL;DR: A preliminary examination of the crude methanol extracts of eight plant species collected from Sudan, revealed that only three plant species had a considerable in vitro antileishmanial activity on Leishmania major promastigotes at a concentration < 0.5 µg/mL.
Abstract: A preliminary examination of the crude methanol extracts of eight plant species collected from Sudan, revealed that only three plant species had a considerable in vitro antileishmanial activity on Leishmania major promastigotes at a concentration < 0.5 µg/mL. The plants Azadirchta indica, Maytenus senegalensis and Eucalyptus globulus gave IC50 values of 11.5, 55 and 78 µg/mL, respectively. Extracts of Pseudocedrela kotscifye and Balanites aegyptiaca had a moderate biological activity, whereas extracts of Sonchous cornatus, Khaya senegalensis and Tamarindus indica failed to exhibit any significant antileishmanial activity against L. major at concentrations <100 µg/mL. Liquid–liquid partitioning of the methanol extracts indicated that fractions of M. senegalensis in dichloromethane and ethyl acetate had the highest antileishmanial activity at 5 µg/mL; IC50 values were 5.01 and 29.7 µg/mL, respectively. Preliminary phytochemical analysis of the dichloromethane fraction revealed terpenoids and traces of phenolic principles but no alkaloid, tannins or flavonoids were detected. As lymphocyte proliferation was inhibited by P. kotscifye and A. indica at higher concentrations (<50 µg/mL) in the presence of phytohaemagglutinin (PHA), M. senegalensis had no significant toxic effect whereas S. cornatus, T. indica and K. senegalensis had a stimulatory impact on lymphocyte cells.

TL;DR: Applications of chromatographic techniques to medicinal plants and Chinese traditional medicines are outlined in this review.
Abstract: Applications of chromatographic techniques to medicinal plants and Chinese traditional medicines are outlined in this review. Areas involved are quantitation of active principles or index or principal components; quality evaluation of crude drugs; identification, characterization and preparative isolation of new compounds for medical use from plants; analysis of pharmaceutical preparations of plant origin and pharmacokinetic and pharmacological studies of herbal drugs and their preparations.
TL;DR: Fractionation of selected plant extracts from Turkish medicinal plants resulted in the identification of active compounds representing a wide range of structures, including alkaloids, terpenoids and phenolic compounds, which can result in the development of novel and safe medicinal agents.
Abstract: Turkey has an extraordinarily rich flora and wide knowledge of their indigenous medicinal plants. Medicinal plants constitute an important componbnt of flora and are widely distributed in different floristic regions of Turkey. Historically, plants have supplied the chemistry for over 25 % of prescription drugs used in human medicine( 1) and such biologically active plants have also provided leads to natural insecticides(2). Accordingly, we are investigating the potential of Turkish medicinal plants as a resource of new chemistry for public health and plant protection. The biological evaluation of substances from plant sources is highly releavant for the identification of lead compounds which can result in the development of novel and safe medicinal agents. During our extensive studies with Turkish medicinal plants, we have isolated and characterized a large number of natural products. On the other hand, a more systematical approach to the discovery of drugs from these plants has been initiated using bioassay-guided fractionation. At the end of this fractionation of selected plant extracts has resulted in the identification of active compounds representing a wide range of structures, including alkaloids, terpenoids and phenolic compounds(3). Fifty five organosoluble extracts prepared from Turkish medicinal plants were investigated for their biological activities against insects, nematodes, plant pathogens and brine shrimp in addition to their biological activities such as antimalarial, anticholinergic, analgesic and antiplatelet activities.
TL;DR: The major aspects of herbal medicine-induced liver injury will be summarized along with the hepatotoxicity seen with mushroom poisoning, aflatoxin and cocaine ingestion.

TL;DR: The antibiotic profile for most of these extracts seems to support their traditional use in treating ailments associated with microbial infections, and detailed chemical and biological investigation of these plants led to isolation of antimicrobial constituents.
Abstract: A number of plant extracts from selected Botswana Medicinal Plants were tested against a battery of organisms for antibiotic activity. The antibiotic profile for most of these extracts seems to support their traditional use in treating ailments associated with microbial infections. Detailed chemical and biological investigation of some of these plants led to isolation of antimicrobial constituents.

TL;DR: A wide range of pharmaceutical secondary metabolites, derived from several higher plants, have been used to benefit mankind for many thousands of years, and are still being used as the drugs of choice for specific therapy.
Abstract: A wide range of pharmaceutical secondary metabolites, derived from several higher plants, have been used to benefit mankind for many thousands of years. Many of these compounds have been known for years, and are still being used as the drugs of choice for specific therapy, e.g. Digitalis cardiac glycosides such as digoxin (Parr, 1989). Furthermore, new compounds are being isolated from the plant kingdom, and are actively screened. The chemical synthesis of most of the plant-derived compounds is possible; however, it is usually complicated, requires several steps in the biosynthetic pathway, and is thus uneconomical. Plant cell cultures offer an alternative approach to produce valuable plant compounds and they can also be used in plant breeding (Verpoorte et al., 1993). Plant tissue culture-derived variation among regenerated plants, or somaclonal variation, has been extensively studied, especially in crop plants such as sugarcane, tobacco, rice, maize and barley (Larkin and Scowcroft, 1981; Peschke and Phillips, 1992). However, surprisingly little information is available on the applications of somaclonal variation in medicinal plants and their cell cultures.
