Extracellular melanogenesis inhibitory activity and the structure-activity relationships of ugonins from Helminthostachys zeylanica roots.
Ugonin J, K, and L, which are luteolin derivatives, were isolated from Helminthostachys zeylanica roots by a series of chromatographic separations of a 50% ethanol/water extract. They were identified using nuclear magnetic resonance (NMR), ultraviolet (UV) spectra, and ultra-performance liquid chromatography coupled to time-of-flight mass spectrometry (UPLC-TOF-MS). In this study, the intra and...
متن کاملUGONIN J FLAVONOID FROM TUNJUK LANGIT (Helminthostachys zeylanica Linn.) ROOT EXTRACT
A flavonoid compound was isolated from dried rihzomes of tunjuk langit (Helminthostachis zaylanica Lin), a traditional medicine from South Sumatera, Indonesia. Extraction was done by maceration methode and separation of isolated compound was conducted by chromatographic technique. The structure of this compound was determined base on spectroscopic data such as including UV, IR, 1-D, 2-D NMR, an...

متن کاملResemblances between the Electromotor Varia- Tions of Rhythmically Reacting Living and Non-living Systems by Ralph
I t is well known that under certain conditions the reaction of iron wire with nitric acid exhibits an automatic r h y t h m of sometimes remarkable regularity, consisting in an alternation of active and passive periods. 1 In a recent study of this phenomenon ~ I have found the most regular rhythms in soft iron wire of low carbon content. Wire drawn from iron prepared by electrolysis of pure so...
متن کاملQuality Control of the Root and Rhizome of Helminthostachys zeylanica (Daodi-Ugon) by HPLC Using Quercetin and Ugonins as Markers.
Daodi-Ugon is the dried root and rhizome of Helminthostachys zeylanica (L.) Hook. and has been used for centuries in the treatment of inflammation, fever, pneumonia, burns, and various disorders. However, the chromatographic methods to determine the phytochemical composition of H. zeylanica have never been reported. This study not only aims to develop a valid high-performance liquid chromatogra...
