The aerial parts of Artemisia mongolica afforded the eudesmane derivative ludovicin B, two coumarins, umbelliferone and esculetin, two methoxylated flavones, eupatilin and pectolinarigenin, as well as a new eudesmane sesquiterpene, 6alpha,8alpha-dihydroxyisocostic acid methyl ester. Structures were
Six new eudesmane-type sesquiterpene derivatives, artemargyinins A-F ( 1 - 6 ) were isolated from the leaves of Artemisia argyi . Their structures were elucidated based on the extensive analysis of spectroscopic data. Compounds 1 - 6 feature a lactone ring-opening eudesmane-type sesquiterpene with
Three new eudesmanes, named artemisidiols A-C, together with eight known compounds, were isolated from the leaves of Artemisia japonica Thunb. (Asteraceae). Their structures were determined on the basis of spectroscopic data. Although oxygenated eudesmanes frequently occur in Asteraceae plants, the
Many anti-inflammatory agents are known to significantly enhance the terminal differentiation of some cancer cells such as leukemia cells. In this study, the effect of yomogin, a eudesmane sesquiterpene lactone isolated from Artemisia princeps with anti-inflammatory activity, was investigated in
Two new sesquiterpenoids, artemlavanins A (1) and B (3), together with fifteen known compounds (2 and 4-17) were isolated from the EtOH extract of Artemisia lavandulaefolia. The structures of new compounds were elucidated by extensive spectroscopic analyses (HRESIMS, 1D and 2D NMR) and ECD
Ten new sesquiterpene alcohols of which seven germacranes, a eudesmane, a guaiane and an oplopane were isolated from the aerial parts of Artemisia alba Turra. Their structures and relative stereochemistry were elucidated by spectral methods ((1)H and (13)C NMR, COSY, HSQC, HMBC, NOESY, and MS). In
A new eudesmane sesquiterpene (1) and a C(10) diyne (2) were isolated from the aerial parts of Artemisia monosperma. The structures of these compounds were determined as rel-1beta,3alpha,6beta-trihydroxyeudesm-4-ene (1) and 1,3R,8R-trihydroxydec-9-en-4,6-yne (2) on the basis of spectral data
Thirteen new sesquiterpenoids, arteannoides F-R (1-13), along with 13 known analogues (14-26), were isolated from the dried aerial parts of Artemisia annua L. Their structures, including absolute configurations, were unambiguously determined by a combination of physical data analyses (HRESIMS, 1D
The phytochemical investigation of the aerial parts of ARTEMISIA ARGYI afforded beta-sitosterol, stigmasterol, alpha-amyrin, beta-amyrin, friedelin, naringenin, quercetin, and four eudesmane derivatives, two of which were new eudesmanolides. The structures of the novel compounds were elucidated by
A new eudesmane sesquiterpenoid, artemisargin A (1), two new guaianolide sesquiterpenoids, artemisargins B (2) and C (3), along with three known sesquiterpenoids (4-6), were isolated from the leaves of Artemisia argyi. Their structures were determined by
Eight new sesquiterpenes, including four guaianolides (1-4), one guaian sesquiterpene (5), one norguaianolide (6), one 1, 10-secoguaianolides (7), and one eudesmane sesquiterpene (8), along with fourteen known sesquiterpenes (9-22) were isolated from the whole plants of Artemisia austro-yunnanensis.
Yomogin (1), an eudesmane sesquiterpene isolated from Artemisia princeps, was tested for the effects on the degranulation process of cultured mast cells and on the nitric oxide production in LPS-activated murine macrophages. It demonstrated a significant inhibition on the release of
