The plant Swertia chirata (Gentianaceae) is known for its multifarious medicinal value in the Indian system of medicine (Ayurveda). Its methanol extracts having antidiabetic activity contains mangiferin, amarogentin, amaroswerin, sweroside and swertiamarin as active constituents. The
Swertia chirayita is an endangered medicinal herb widely used as an antidiabetic. It contains two major classes of metabolites, secoiridoids and xanthones, i.e. swertiamarin, mangiferin, amarogentin and amaroswerin. The biosynthetic pathways for these chemical constituents are not completely
Swertia chirata is a bitter plant, used in the Indian system of medicine (Ayurveda) for various human ailments. The bioactive constituents include the xanthone and secoiridoid glycosides consisting of mangiferin, amarogentin, amaroswerin, sweroside and swertiamarin. Methanolic extracts of S. chirata
This article describes the study to standardize phytochemically and distinguish Swertia chirayita from that of possible substitution/adulteration using ultra performance liquid chromatography (UPLC) with photodiode array detector (PDA) and chemometric tools viz. principal component analysis (PCA)
Swertia mussotii Franch. and Swertia chirayita Buch.-Ham. have been commonly used under the same name "Zangyinchen" for the treatment of liver and gallbladder diseases in traditional Tibetan medicine. Detailed characterization and comparison of the complete set of metabolites of these two species
The present study was aimed to determine the therapeutic effects of Swertia chirayita leaves against oxidative and inflammatory injuries in Freund's complete adjuvant (FCA) induced arthritic rats. The extract was evaluated for its phytoconstituents and various invitro antioxidant properties followed
The crude extract of Swertia chirayita, an important medicinal plant of Nepal, is locally used for many diseases including type 2 diabetes. In this study, crude aqueous and 12% ethanol solution extracts of S. chirayita collected from nine districts of Nepal were analyzed for anti-diabetic-linked
A rapid analytical method has been developed to determine xanthone and secoiridoid glycoside in in vitro and in vivo Swertia chirayita extracts. Ultra performance liquid chromatography-electrospray ionization mass spectrometry (LC-ESI/MS) was applied and validated for the analysis of xanthone and
Swertia chirayita, an endangered medicinal herb, contains three major secondary metabolites swertiamarin, amarogentin and mangiferin, exhibiting valuable therapeutic traits. No information exists as of today on the biosynthesis of these metabolites in S. chirayita. The current study reports the
Genus Swertia is valued for its great medicinal potential; mainly Swertia chirayita (Roxb. ex Fleming) H. Karst. is used in traditional medicine for a wide range of diseases. Seco-iridoid glycosides like swertiamarin is referred with enormous pharmacological potentials. The aim of the study was to
CNS activity of swertiamarin, a secoiridoid glucoside from Swertia chirata, was evaluated. An apparent anomaly, associated with the unanticipated finding that the alcoholic extracts (excluding mangiferin) of S. chirata significantly reversed the mangiferin-induced CNS-stimulating effects in albino
Extracts from Swertia chirata (family Gentianaceae) have antidiabetics and antioxidant activity, largely attributed to the flavonoids and secoiridoids, which are a major class of functional components in methanolic extracts from aerial part of plants. In order to facilitate analysis of systemic
A novel free radical reaction combined with liquid chromatography electrospray ionization tandem mass spectrometry (FRR-LC-PDA-ESI/APCI-MS/MS) screening method was developed for the detection and identification of radical-scavenging natural antioxidants. Functionalized graphene was prepared by
BACKGROUND
The genus Swertia is reported to contain potent bitter compounds like iridoids, xanthones and c-glucoflavones that are known to heal many human disorders. In contrast to high ethnomedicinally valued Swertia chirayita, its other species have not been studied extensively, in spite of their
There is the need of development of liposomes based nanomedicines formulation for the better efficacy and safety of the available drugs in the market. Liposomes have various applications in the field of pharmaceutical and medical field for their drug target potential, diagnostic importance and
