deoxyandrographolide/andrographis

A new diterpene glucoside has been isolated from the leaves of Andrographis paniculata and its structure elucidated as deoxyandrographolide-19beta-D-glucoside on the basis of chemical and spectral evidence. A detailed proton magnetic resonance study of the diterpene was crucial in the structure

In this paper a micellar electrokinetic capillary chromatographic (MEKC) method has been developed for determining the active components (andrographolide, deoxyandrographolide and neoandrographolide) in water:ethanol extracts of the Chinese crude herb Andrographis paniculata and its preparations

OBJECTIVE Andrographis paniculata (AP) has been found to display hepatoprotective effect, although the mechanism of action of the active compounds of AP in this context still remains unclear. Here, we evaluated the hepatoprotective efficacy of 14-deoxyandrographolide (14-DAG), a bioactive compound

Andrographis paniculata (AP) is a traditional medicinal plant of Ayurveda. It grows widely in Asia and is prescribed in the treatment of liver diseases. Here we have investigated the beneficial role of 14-deoxyandrographolide (14-DAG), a bioactive diterpenoid from AP, against alcoholic steatosis in

14-Deoxyandrographolide (14-DAP) is a labdane diterpene isolated from Andrographis paniculata with previously reported calcium channel blocking activity. Its potential platelet activating factor (PAF) antagonistic activity in bovine neutrophils was assessed. 14-DAP, in concentrations between 10-100

Skeletal muscle is the principal site for postprandial glucose utilization and augmenting the rate of glucose utilization in this tissue may help to control hyperglycemia associated with diabetes mellitus. Here, we explored the effect of Deoxyandrographolide (DeoAn) isolated from the Andrographis

BACKGROUND The aim of the present study is to evaluate the possible mechanism of the vasorelaxant effect of the Andrographis paniculata chloroform extract (APCE) and diterpenoids, such as, 14-deoxyandrographolide (DA) and 14-deoxy-11, 12-didehydroandrographolide (DDA), on rat aortic

A quantitative proton nuclear magnetic resonance technique (qHNMR) has been successfully introduced to quantify andrographolide, dehydroandrographolide, deoxyandrographolide and neoandrographolide in Andrographis paniculata, a commonly used important traditional Chinese medicine. Creative use of

The in vitro cytotoxicities of the ethanol extract of Andrographis paniculata (APE) and its main diterpenoid components were evaluated in various cancer cells. APE was found to be significantly growth inhibitory to human acute myeloid leukemic HL-60 cells with an IC (50) value of 14.01 microg/mL

Andrographis paniculata from different parts and origins were analyzed by UPLC-PDA fingerprint to provide refererice for related preparation technology. Using the peak of andrographolide as reference, 27 common peaks were identified, and digitized UPLC-PDA fingerprints for 23 batches of andrographis

OBJECTIVE To establish the specific fingerprint of alcohol extract of Andrographis paniculata by HPLC. METHODS The analysis was performed on Cosmosil 5C18 -MS-II (250 mm x 4. 6 mm, 5 µm) column, with gradient phase consisting of acetonitrile and water at the flow rate of 1. 0 mL/min. The UV

OBJECTIVE To establish an analytical method for characteristic fingerprint and determination of main components of Andrographis paniculata Extract by UPLC. METHODS The chromatographic conditions were Waters ACQUITY UPLC BEH-C18 (2. 1 mm x 0 mm,1.7 μm)by gradient elute using acetonitrile-water as

OBJECTIVE To study the diterpenoids in the 85% ethanol extract of the aerial parts of Andrographis paniculata. METHODS Fourteen diterpenoids from the 85% EtOH extract were isolated by the silica gel, Sephadex LH-20, ODS column chromatography and HPLC, and their structures were identified by the

To discover new natural-product-based pesticides, we structurally modified andrographolide, a labdane diterpenoid isolated from Andrographis paniculata, and stereoselectively prepared a series of 12α-(substituted)benzylamino-14-deoxyandrographolide derivatives (I-V). Three-dimensional structures of

A rapid and sensitive silver ion high-performance liquid chromatographic (Ag[I]-HPLC) method is developed for the simultaneous determination of the biologically active diterpenoids andrographolide, 14-deoxy-11,12-didehydroandrographolide, 14-deoxyandrographolide, and neoandrographolide in
