New Guaianolide Sesquiterpene Lactones and Other Constituents from Pyrethrum pulchrum.

is a rare Mongolian plant species that has been traditionally used as an ingredient in various remedies. Bioactivity-guided fractionation performed on the methanol extract of its aerial parts led to the isolation of 2 previously undescribed guaianolide-type sesquiterpene lactones, namely 1,10-epoxy-8-hydroxyguaia-3,11(13)-dien-6,12-olide (1: ) and 1,8,10-trihydroxyguaia-3,11(13)-dien-6,12-olide (2: ), along with the isolation or chromatographic identification of 11 compounds, arglabin (3: ), 3-hydroxycostunolide (4: ), isocostic acid (5: ), ()-9-(2-thienyl)-6-nonen-8-yn-3-ol (6: ), ()-9-(2-thienyl)-6-nonen-8-yn-3-ol (7: ), , , , -tetra-p-coumaroyl spermine (8: ), chlorogenic acid (9: ), 3,5-di--caffeoylquinic acid (10: ), 3,5-di--caffeoylquinic acid methyl ester (11: ), 3,4-di--caffeoylquinic acid (12: ), and tryptophan (13: ). Their structures were assigned based on spectroscopic and spectrometric data.

Bioactive flavonoids from plant extract of and its acute toxicity.

Ledeb. has been a phytochemically unexplored Mongolian medicinal folklore plant. In this study, its total flavonoid content was determined and fourteen flavonoids () were isolated from the aerial parts of .

Antifungal activity of Mongolian medicinal plant extracts.

The antifungal activity of extracts obtained from 14 medicinal plants of the mongolian flora were investigated by measuring their minimal inhibitory concentration (MIC) against fungi cause of cutaneous diseases such as species, dermatophytes and . Among the species examined, L., L.

Initial Trials With Susceptibility-Based and Empiric Anti- Therapies in Mongolia.

Mongolia has a high prevalence of infection and gastric cancer. We conducted a prospective, randomized, single-blind study to evaluate the efficacy of common regimens in Mongolia and to obtain specimens for susceptibility testing. Empiric treatments: 270 patients with confirmed infection were randomized to receive 10 days clarithromycin-triple therapy (Clari-TT) ( = 90), modified bismuth quadruple therapy (M-BQT) ( = 90), or sequential therapy (ST) ( = 90).

Artemisioside, a new monoterpene glucoside from the aerial parts of Artemisia ordosica (Asteraceae).

A new monoterpene glucoside, artemisioside, was isolated from the aerial parts of Artemisia ordosica Krasch. (Asteraceae). The chemical structure was elucidated from physicochemical data and by the application of Klyne's rule.

Intestinal protozoan infections and echinococcosis in the inhabitants of Dornod and Selenge, Mongolia (2003).

The status of intestinal parasitic infections and seroprevalence of cystic echinococcosis in the inhabitants in Dornod and Selenge, Mongolia, was observed with stool and serum samples from 165 and 683 residents from August 9 to August 15, 2003. A total of 10 inhabitants (6.1%) were found to be infected with protozoan cysts or oocysts by stool examinations; 7, 1 and 2 cases with Entamoeba coli, Giardia lamblia and Cryptosporidium parvum, respectively.
