ainsliaea rubrifolia/inflammation

Four new sesquiterpenoids (1-4) and six known sesquiterpenoids (5-10), were isolated from the EtOAc phase of the ethanolic extract of Ainsliaea yunnanensis. Their structures were established by spectroscopic methods, including 1-D, 2-D NMR and HPLC-MS. All

BACKGROUND Ainsliaea fragrans Champ. (A. fragrans) is a traditional Chinese herbal that contains components like 3,5-dicaffeoylquinic acid and 4,5-dicaffeoylquinic acid. It exhibits anti-inflammatory activities which has been used for the treatment of gynecological diseases for many years in China.

Three new sesquiterpenoids, 4α-hydroxyeudesm-11(13)-en-12-yl 3-methylbutanoate (1), diaspanolide E (2), and (13α)-germacra-1(10),4-dien-12,8α-olid-15-oic acid (3), along with eight known sesquiterpenoids (4 - 11), were isolated from the aerial parts of Ainsliaea henryi. The chemical structures of

Cervicitis is an extremely common gynecological disease and can be induced by diverse factors such as Neisseria gonorrhoeae, Chlamydia trachomatis, and Mycoplasma genitalium infections. Long-term unhealed cervicitis may lead to a series of diseases including endometritis, salpingitis, pelvic

Three new sesquiterpenes: 4-acrylic-6-methyl-α-tetralone (1), ainsliaea acid A (2) and ainsliaea acid B (3), together with 8 known compounds (4-11) were isolated from the whole herb of Ainsliaea glabra and their structures were established by means of 1D and 2D NMR spectroscopy and HR-ESIMS.

Investigation of the ethanol extract of the whole plant of Ainsliaea yunnanensis led to the isolation of four new dimeric sesquiterpene lactones, ainsliadimer F-I (1-4), together with seven known dimeric sesquiterpene lactones (5-11) and ten sesquiterpenes (12-21). Their structures were elucidated

One new pentacyclic triterpenoid, 3β-carboxylicfilic-4(23)-ene (1), and three known pentacyclic triterpenoids, adian-5-en-3α-ol (2), fernenol (3), and fern-7-en-3β-ol (4) were isolated from the petroleum ether phase of the ethanolic extract of Ainsliaea yunnanensis Franch. Their structures were
