Diarylpentanoids and phenylpropanoids from the roots of Anthriscus sylvestris (L.) Hoffm.

Three pairs of undescribed diarylpentanoid enantiomers (1-3) and five undescribed phenylpropanoids (4-8), along with seven known compounds, were isolated from the roots of Anthriscus sylvestris. The structures of compounds (1-8) were determined by analysis of their 1D and 2D NMR spectra, HRESIMS, and electronic circular dichroism. In addition, the inhibitory activities against hypoxia-stimulated pulmonary arterial smooth muscle cells abnormal proliferation were evaluated by MTT assay.

Salviamilthone A-O, diterpenoid quinones from Salvia miltiorrhiza.

Fifteen undescribed diterpenoid quinones salviamilthone A-O (1-15), together with three known diterpenoid quinones (16-18), were isolated from the roots of Salvia miltiorrhiza Bunge. Their structures were elucidated using 1D and 2D NMR data, while the relative and absolute configurations were confirmed by NOESY correlations and comparison between experimental and calculated ECD spectra. In the evaluation of bioactivities, salviamilthone J (10), salviamone (18) (10 μM) significantly increased cell viability and decreased the expression of IL-1β in lipopolysaccharide-induced BEAS-2B cells.

Diterpenoid quinones from the Salvia miltiorrhiza and their lung protective activity.

Seven new diterpenoids quinones (1-6), together with five known ones (7-11), were isolated from the roots of Salvia miltiorrhiza Bunge. Their structures were elucidated by using 1D and 2D NMR data, while the relative and absolute configurations were confirmed by interpretations of the NOESY correlations and comparison of the experimental and calculated ECD spectra. In the evaluation of bioactivities, salviamilthiza C (3), significantly increased cell viability and decreased the expression of IL-1β in LPS-induced BEAS-2B cells.

Ionones and lignans from the fresh roots of Rehmannia glutinosa.

Nine undescribed compounds, together with 21 known components, were isolated from the fresh roots of Rehmannia glutinosa. Their structures were elucidated based on spectroscopic data analysis, and the absolute configurations of undescribed compounds were determined by comparison of their calculated and experimental electronic circular dichroic (ECD) spectra and interpretation of their optical rotation data. The α-glucosidase inhibitory effects of the isolated compounds were investigated and all of them exhibited slightly inhibitory activities.

Ten undescribed diterpenoid quinones derived from the Salvia miltiorrhiza.

This study aimed to report the structure elucidation of the compounds isolated from Salvia miltiorrhiza, and their biological evaluations. Ten undescribed diterpenoid quinones and 10 known analogues were isolated from the dried roots of S. miltiorrhiza.

Iridoid glycosides and lignans from the fruits of Gardenia jasminoides Eills.

Four previously undescribed iridoid glycosides, including two bis-iridoid glycosides, and three undescribed lignans, together with 16 known analogues, were isolated from the fruits of Gardenia jasminoides Eills. Their structures were elucidated on basis of spectroscopic methods, and the absolute configurations of three of the unknown compounds were determined by interpretation of their electronic circular dichroic (ECD) and [α] [Formula: see text] data. The α-glucosidase inhibitory effects of the isolated compounds were evaluated and all the compounds exhibited slightly inhibitory activity with the values of IC greater than 50 μM.

Renoprotective activity of a new amide and a new hydroxycinnamic acid derivative from the fresh roots of .

A new amide, named rehmagluamide (), and a new hydroxycinnamic acid derivative, named nepetoidin F (), together with six known compounds, 2'--methyluridine (), puroglutamic acid (), biliverdic acid (), peterolactam (), nicotinic acid (), nicotinamide (), were isolated from the fresh roots of . All the structures of compounds were identified by the interpretation of their spectroscopic data and comparison with those reported in the literatures. The protective effects of compounds on normal rat kidney tubule epithelioid (NRK-52e) cells injury induced by LPS were investigated.
