A New Cyclic Octopeptide from Schnabelia oligophylla

From the methanol extract of the whole plant of Schnabelia oligophylla Hand.-Mazz. (Lamiaceae), a new cyclic octopeptide, named schnabepeptide (1), was isolated by silica gel chromatography. Its structure was elucidated by spectroscopic analyses and the absolute configuration of the amino acid units, except for proline and glycine, were assigned by chiral HPLC analysis. Bio-assay showed that schnabepeptide (1) exhibited an immunosuppression activity on T/B lymphocytes. Along with the new compound, seven known compounds, octadeca-9,16-dioxo-10(E),12(Z),14(E)-trienoic acid (2), 12,16-epoxy-11,14-dihydroxy-17(15→16),18(4→3)-diabeo-abieta-3,5,8,11,13,15-hexene-2,7-dione (teuvincenone F, 3), abscisic acid (4), β-sitosterol (5), daucosterol (6), stigmasteryl 3-O-β- D -glucopyranoside (7) and palmitic acid (8), were also isolated from this plant.     

New sesterterpenoids and other constituents from Salvia dominica growing wild in Jordan

A new nor-oleanane triterpene 24-nor-4(23)-12-oleanadien-2α,3α,28-triol (1) and two new sesterterpenes salvidominicolide A (2), salvidominicolide B (3) together with fifteen known compounds were isolated from Salvia dominica L. growing wild in Jordan. The known compounds comprised six flavones, three triterpenes, one diterpene, one sesterterpene, two oxygenated monoterpenes, one sterol glucoside and one flavone glucoside. The isolated compounds were elucidated by extensive spectroscopic methods including NMR (1D and 2D), UV, IR and MS (HRMS).     

New triterpenoids from Leonurus japonicus (Lamiaceae)

Three new triterpenoids (1, 4, and 5), together with 17 known analogues, were isolated from the ethyl acetate soluble portion of the EtOH extract of Leonurus japonicus Houtt. Their structures were determined by spectroscopic analysis. All known triterpenoids were isolated from the genus Leonurus for the first time. Among them, triterpenoids 2–3, 9–12, and 16–20 were first isolated from the family Lamiaceae. Furthermore, the cycloartane, taraxastane, ursane, lupane, euphane, and dammarane types are reported here for the first time from the genus Leonurus.

Two new oleanane-triterpenoid saponins, clinograsaponins A ( 1 ) and B ( 2 ), together with twelve known ones ( 3 – 14 ), were isolated from the whole herb of Clinopodium gracile (Bentham) Matsumura. Their structures were determined by spectroscopic analysis and chemical method. All the isolated compounds were evaluated for their activities against ATP-citrate lyase (ACLY) and nuclear factor kappa B (NF-κB).
