“…The 1 H NMR spectral data for H -3 /δ H 7.4 ppm) indicated the presence of a 4 -substituted enol ether system of an iridoid moiety. The spectrum signal at δ H 4.6 /H' exhibited the presence of an anomeric proton (Gousiadou, et al, 2007). Signals observed at δ H 7.1, 6.6, 7.5., 6.8 and 6.3 are all characteristic of an aromatic protons (Dominguez, et al ., 2007).…”

Three iridoid glycosides were isolated from the n-butanol fraction of the root extract of Stachytarpheta angustifolia (verbenaceae). Their structures were elucidated by using a combination of 600MHz/150 MHz ID and 2D NMR techniques (COSY, NOESY, DEPT, HSQC and HMBC) and by FABMS and HRESIM. Compound 1 was characterized as Citrifolinoside, (2) as Serratoside and 3 is determined as 6 -O -(3 " -O -trans -cinnamoyl) -α -L -rhamnopyranosyl catalpol heptaacetate.

“…The H -9/ δ H 2.72ppm with coupling constant at J = 9.7H Z was also found to couple with H -5 and H -1 of the aglycone (Kalpoulzakis et al, 1999;Kemp, 1991). The coupling of H -5 exhibited a dihedral angle to be at 0 0 , thus revealing the stereochemistry of pyran and cyclopentane ring fused at its position (Gousiadou et al, 2007).…”

Scutellaria (Lamiaceae), which contains over 350 species, usually known as skullcaps, is found throughout Europe, the United States, and East Asia. In traditional Chinese medicine, several species are used to wipe out heat-evil and remove surface ills (TCM). The current study examines the ethnopharmacology, biological activity, and chemical substances associated with Scutellaria species. More than 295 chemicals, including flavonoids and diterpenes, have been identified. Scutellaria and its active principles have been shown in studies to have a wide range of pharmacological activities, including antioxidant, antimicrobial, antifeedant, phytotoxic, acaricidal toxicity, antibacterial, anti-inflammatory, and antianalgesic activities. Currently, effective monomeric compounds or active components from Scutellaria have been evaluated for pharmacological action in vivo and in vitro. More data facilitates applications and exploitation of novel medication development.

The idea of studying the iridoids from the Melampyrum bihariense Kern has started from the few data found about the chemical composition of this species. The literature mentions the presence of iridoids found in two species of Melampyrum: Melampyrum arvense and Melampyrum cristatum. The study consists of a qualitative and quantitative analysis by modern chromatographic methods, TLC.TLC coupled with photo-densitometry as well as chromatography on the high performance column (LC/MS). The methanol extract was done from the flowers and leaves of Melamphyrum bihariense. For the TLC and HPLC, the aucubin was used as standard solution. The obtained chromatogram was examined in visible light spectrum, and then it was revealed with sulphuric anisaldehyde, emphasizing the brown coloured spots. In the TLC case, the chromatographic plate was scanned with a Shimadzu CS9000 photo densitometer after spraying with iron chloride, and for the HPLC the analytical column Atlantis HILIC was used 100 mm x 3.0 mm, 3.5 ?m (water), and the ESI source of ions (electrospray ionisation). After the TLC analysis, the iridoids concentration found in the aucubin is 0.23 mg/mL in flowers and 0.24 mg/mL in leaves, and by the LC/MS method the concentration is of 1.8125 mg/ml in flowers and 2.3037 mg/ml in leaves.
