Objective: To investigate the chemical constituents from Lamiophlomis rotata and the bioactivities of 8-epideoxyloganic acid.
Method: The constituents were isolated by using a combination of various chromatographic techniques including column chromatography over ployamide, silica gel and Sephadex LH-20. Structures of the isolates were identified by spectroscopic data analysis. Bioactivities were screened by using models in vivo.
Result: Five constituents were isolated. 8-epideoxyloganic acid was isolated for the first time in L. rotata and also in lamioplomis genus. 8-epideoxyloganic acid could significantly inhibit aectic acid-induced twisting times and slower the time of homeostatsis, also inhibit xylene-induced ear edema in mice.
Conclusion: 8-epideoxyloganic acid possesses bioactivities of analgesia, homeostasis and anti-inflammatory.

is a traditional Chinese herbal medicine that grows in the Qinghai-Tibet Plateau region at a 3100-5000 m altitude. Iridoid compounds are the main active compounds of the used as medical ingredients and display anti-inflammatory, analgesic, and hepatoprotective properties. To better understand the biological mechanisms of iridoid compounds in this species, we performed a comprehensive analysis of the transcriptome and metabolome of leaves from four different regions (3540-4270 m).

From two species of Sutera (S. foetida and S. cordata) (Scrophulariaceae tribe Limoselleae) were isolated three known secoiridoid glucosides (12-14) as well as four iridoid congeners (8-11), all biosynthetically derived from iridodial glucoside (and/or deoxyloganic acid).

Rapid production of reactive oxygen species (ROS) and upregulation of beta2 integrin by leucocytes are two important inflammatory responses in human leucocytes. To evaluate whether three phenylpropanoid glycosides (acteoside, crenatoside, and rossicaside B) and two iridoid glucosides (boschnaloside and 8-epideoxyloganic acid) identified from two medicinal plants with similar indications (Orobanche caerulescens and Boschniakia rossica) exhibited anti-inflammatory activity, their effects on N-formyl-methionyl-leucyl-phenylalanine (fMLP) and phorbol-12-myristate-13-acetate (PMA)-activated peripheral human neutrophils (PMNs) and mononuclear cells were examined. Pretreatment with 1-50 microM phenylpropanoid glycoside concentration-dependently diminished PMA- and fMLP-induced ROS production with IC50 values of approximately 6.

Novel ceramides, rel-(3S,4S,5S)-3-[(2R)-2-hydroxycosanoyl-hexacosanoylamino]-4-hydroxy-5-[(4Z)-tetradecane-4-ene]-2,3,4,5-tetrahydrofuran (1a-g), and a new glucoceramide, 1-O-beta-D-glucopyranosyl-(2S,3S,4R,8E)-2-[(2R)-2-hydroxytetracosanoylamino]-1,3,4-octodecanetriol-8-ene (2) were isolated from the aqueous ethanolic extract of the roots of Incarvillea arguta, together with eight known compounds: beta-sitosterol (3), oleanolic acid (4), ursolic acid (5), piperin (6), maslinic acid (7), beta-sitosterol 6'-O-acyl-beta-D-glucopyranoside (8), 8-epideoxyloganic acid (9), and plantarenaloside (10). Their structures were elucidated on the basis of spectral data including IR, MS, NMR [1H NMR, 13C NMR (distortionless enhancement by polarization transfer), 1H-1H COSY, heteronuclear multiple-quantum coherence, and heteronuclear multiple-bond coherence correlations]. The relative configurations were established by nuclear Overhauser effect spectroscopy experiments and by comparison of the NMR spectral data and coupling constants with those already reported in the literature.
