lantana fiebrigii/phosphatase

During the search for new protein tyrosine phosphatase (PTP) 1B inhibitors, EtOH extracts from the aerial parts of Lantana camara L. (lantana) collected at Manado (Indonesia) and two subtropical islands in Japan (Ishigaki and Iriomote Islands, Okinawa) exhibited potent inhibitory activities against

A toxin fraction was obtained from Lantana camara L (red variety) leaves by batch extraction and column chromatography on silica gel (60-120 mesh). The main constituents of the toxin preparation were lantadene A and lantadene B and it was devoid of reduced lantadene A. Oral administration (125 mg/kg

A new digalacturonide flavone, luteolin 7-O-beta-galacturonyl-(2 --> 1)-O-beta-galacturonide (1), was isolated along with nine known flavone glycosides from the aqueous methanolic extract of Lantana camara (L.) flowers. Their structures were determined on the basis of the spectral data. The extract

Lantadene C (22 beta-2-methylbutanoyloxy-3-oxoolean-12-en-28-oic acid) isolated from the leaves of the hepatotoxic plant Lantana camara var. aculeata (Red) has been found to be identical with dihydrolantadene A reported earlier. Molecular structure of lantadene C has been deduced from single crystal

Lantadene A (22 beta-angeloyloxy-3-oxo-olean-12-en-28-oic acid), a pentacyclic triterpenoid compound from lantana (Lantana camara) leaves has been obtained in two polymorphic forms I and II. Form I had white, fluffy, and rod-shaped uniform crystals. Form II particles were irregular, shining, and

Earthworms are known to increase availability of heavy metals in soils and also play an important role in maintaining the structure and quality of soil. The introduction of earthworms into soils contaminated with metals in the presence of a potential hyperaccumulator has been suggested as an aid for

Plant species, viz Cleistanthus collinus, Lantana camara, and Strychnos nux-vomica are being traditionally used for pest management in rice. However, limited investigation has been carried out to understand the toxic effect of these materials on soil microbes. Hot water extracts of these plants were

BACKGROUND In the field conditions, animals regularly consume small quantities of lantana leaves either while grazing or due to mixing with regular fodder. The hypothesis of this study was that consumption of lantana toxins over a long period of time leads to progression of sub-clinical disease.

Field and laboratory experiments were conducted in March, 2008 in El-Nouzha garden, Alexandria governorate. Pre-and post treatment inspections of the insects were examined and recorded before and after (2,4,8, and 12 weeks). Spraying was applied to evaluate the efficiency of the tested compounds,

Three red kangaroos (Megaleira rufus), an adult male, an adult female, and a yearling, were exposed in bedding and food to coastal bermuda hay that contained the toxic plant Lantana camara. The adult male exhibited signs of anorexia, depression, lethargy, and jaundice. The adult female was presented

A partially purified preparation of toxin isolated from lantana (Lantana camara L., red variety) leaves, called fraction C, was obtained in two crystalline forms: form I, white, fluffy, rod-shaped and form II, irregular, polyhedral, shining crystals. The two forms differed in melting point behaviour

Hepatocellular carcinoma is one of the leading causes of death in cancer and yet no drug has proven to be a successful candidate for its treatment in advanced stages. Ursolic acid stearoyl glucoside (UASG) is a newly discovered triterpene in Lantana camara and there lies a possibility that it

The aim of the present study was to evaluate the hepatoprotective activity of lantadene A against acetaminophen-induced liver toxicity in mice was studied. Activity was measured by monitoring the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP)

Lantana toxicity of guinea pigs elicited an increase in hematocrit, erythrocyte and leukocyte number, hemoglobin, urea-nitrogen and bilirubin contents in the blood of the affected animals. Most of the bilirubin was present in the conjugated form. Enzyme activities of glutamic oxaloacetic

Oral administration of lantana leaf powder to guinea pigs caused an increase in the hepatic postmitochondrial fraction:homogenate ratios of activities of lysosomal enzymes--acid phosphatase, cathepsin B and DNase II. Enzyme activities of glucokinase, aldolase, lactate dehydrogenase and
