Metabolic syndrome is described as a group of risk factors in which at least three unhealthy medical conditions, including obesity, high blood sugar, hypertension or dyslipidemia occur simultaneously in a patient. These conditions raise the risk for diabetes mellitus and cardiovascular diseases. Many recent studies have focused on herbal remedies and their pharmacological effects on metabolic s...

Jujuba (Ziziphus jujuba) has a long history of usage as fruit and remedy. The main biologically active components are vitamin C, phenolics, flavonoids, triterpenic acids, polysaccharides. Many phytochemical studies jujuba fruits indicate that Z. important biological effects, such the anticancer, anti-inflammatory, antiobesity, immunostimulant, antioxidant, hepatoprotective, neuroprotective gast...

As a part of our studies on the biologically active substances from Spanish plants, we have undertaken an investigation of the chemical constituents of a typical mediterranean species, Phillyrea latifolia L. (Oleaceae). Two secoiridoid glycosides, three phenylpropanoid glycosides, one lignane and two triterpenic acids were isolated from the leaves of this species and identified. The phytochemic...

Combining antibiotics with resistance reversing agents is a key strategy to overcome bacterial resistance. Upon screening antimicrobial activities of plants used in traditional medicine, we found that a leaf dichloromethane extract from the shea butter tree (Vitellaria paradoxa) had antimicrobial activity against methicillin-resistant Staphylococcus aureus (MRSA) with further evidence of synerg...

A simple and rapid reversed-phase HPLC-UV method was developed for the determination of triterpenic acids in the crude extract of Prunellae Spica. Five triterpenic acids were extracted and isolated from P. Spica as marker compounds for use in the quality control of herbal medicines. Various solvent extraction techniques were evaluated, and the greatest efficiency was observed with sonication in...

Herbal preparation(s) The following designations are synonyms to define a highly refined and purified ethanolic (70% V/V) extract containing asiaticoside (40%) and 60% of triterpenic genins: asiatic acid (29-30%), madecassic (acid 29-30%) and madasiatic acid (about 1%). TECA (titrated extract of Centella asiatica) TTFCA (total triterpenoid fraction of Centella asiatica) TTF (total triterpenic f...

Isomeric triterpenic acids of oleanolic acid (OA) and ursolic acid (UA) both have very low ultraviolet absorption and always exist in the same plant, so the separation and simultaneous determination of them have been a difficult task. In this study, a sensitive method combining dispersive liquid-liquid microextraction (DLLME) with HPLC-UV was developed for the extraction and determination of OA...

Polygonum capitatum (Polygonaceae) exists in rural areas of Southwest China and some other Asian countries. Its aerial part or whole herbal plant has been used as a Miao ethnomedicine against urinary system diseases, infections, pyelonephritis, diarrhea, so on. The progress phytochemical research on P. over the past decades is summarized. Two hundred three chemical constituents that have isolat...
