In parts of Africa and Asia, self-medication with a hot water infusion of Artemisia annua (Artemisia tea) is a common practice for a number of ailments including malaria and cancer. In our earlier work, such an extract showed better potency than artemisinin alone against both chloroquine-sensitive and -resistant parasites. In this study, in vitro tests of the infusion in MCF7 cells showed high IC50 values (>200 ?M).

Desmodium gangeticum is widely used in the indigenous system of medicine in India and is reported to contain flavone and isoflavonoid glycosides. It forms the ingredient of many Ayurvedic formulations used for diabetes. The present study was thus aimed at evaluating the insulin secretion and antidiabetic activity of Desmodium gangeticum. Treatment of diabetic rats with aerial parts of D. gangeticum extract (DG, 100 and 250 mg/kg body weight) for 3 weeks showed a significant reduction in blood glucose. D.

Arnica montana is a medicinally important plant due to its broad health effects, and it is used in Ayurvedic, Homeopathic, Unani, and folk medicines. We have used LC-MS(n) (n = 2-5) to detect and characterize in Arnica flowers 11 quantitatively minor fumaric and methoxyoxalic acid-containing chlorogenic acids, nine of them not previously reported in nature.

Our previous studies found that 4 compounds, namely pseudohypericin, amentoflavone, quercetin, and chlorogenic acid, in Hypericum perforatum ethanol extract synergistically inhibited lipopolysaccharide (LPS)-induced macrophage production of prostaglandin E2 (PGE2). Microarray studies led us to hypothesize that these compounds inhibited PGE2 production by activating suppressor of cytokine signaling 3 (SOCS3). In the current study, siRNA was used to knockdown expression of SOCS3 in RAW 264.7 macrophages and investigated the impact of H.

Achillea millefolium L. sensu lato (yarrow) is the best-known species of the genus Achillea due to numerous medicinal applications both in folk and conventional medicine. Phenolic compounds such as flavonoids and phenol carbonic acids are present in yarrow and constitute one of the most important groups of pharmacologically active substances. In the present study, yarrow flowers gathered from native populations in different locations of Lithuania were analyzed for phenolic compound composition. High-performance liquid chromatography (HPLC) was used for chemical analyses.

AIM OF THE STUDY: Species of Lychnophora are used in Brazilian folk medicine as analgesic and anti-inflammatory agents. Chlorogenic acid (CGA) and their analogues are important components of polar extracts of these species, as well in several European and Asian medicinal plants. Some of these phenolic compounds display anti-inflammatory effects. In this paper we report the isolation of CGA from Lychnophora salicifolia and its effects on functions involved in neutrophils locomotion. MATERIALS AND METHODS: LC-MS(n) data confirmed the presence of CGA in the plant.

ETHNOPHARMACOLOGICAL RELEVANCE: Baccharis trimera (Less.) DC. (Asteraceae) is a species native to South America used in Brazilian folk medicine to treat gastrointestinal and liver diseases, kidney disorders and diabetes. Previous studies from this laboratory confirmed the antacid and antiulcer activities of the plant aqueous extract (AE) in rat and mouse models. AIM OF THE STUDY: To investigate the mechanisms involved in the antacid action of AE and isolated compounds from Baccharis trimera.

BACKGROUND: Crassocephalum crepidioides, a plant distributed in Okinawa Islands, is known in folk medicine; however, its anticancer activity has not been investigated. The aim of this study was to determine the in vitro and in vivo antitumor activities of C. crepidioides on murine Sarcoma 180 (S-180) and related molecular mechanisms. METHODS: The antitumor effect of C. crepidioides was evaluated in S-180-cell-bearing mice. Cell growth was assessed using a colorimetric assay. Nitrite and nitrate levels were measured by colorimetry.

ETHNOPHARMACOLOGICAL RELEVANCE: Tithonia diversifolia (Hemsl.) A. Gray has been commonly used in folk medicine to treat abscesses, microbiological infections, snake bites, malaria and diabetes. Both anti-inflammatory and anti-malarial properties have been identified using appropriate assays, but the effective doses have demonstrated toxic effects for the experimental animals. Most of the pharmacological activities have been attributed to sesquiterpene lactones (STLs) and some chlorogenic acid derivatives (CAs) in the leaves of this species.

Flos Lonicerae is a medically useful traditional Chinese medicine herb. However, little is known about the antioxidant properties of Flos Lonicerae extracts. Here the antioxidant capacity of water, methanolic and ethanolic extracts prepared from Flos Lonicerae to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and reduce Fe(3+) to Fe(2+) is examined. Chlorogenic acid, a major component of Flos Lonicerae, is identified and further purified from 70% ethanolic extract with high performance liquid chromatography (HPLC) and its antioxidant capacity is characterized.
