In order to reveal the chemical characteristics of Glycyrrhiza uralensis growing in Mongolia and to clarify whether it can be the source of Glycyrrhizae Radix used in Japan, eight major bioactive
constituents in the underground parts of G. uralensis collected in Mongolia were quantitatively analyzed and compared with Glycyrrhizae Radix produced in China. Most of the 15
samples from eastern, southern and western parts of Mongolia contained 26.95–58.55 mg/g of glycyrrhizin, exceeding the criterion
(25 mg/g) assigned in the Japanese Pharmacopoeia. The sample collected in Tamsagiyn hooly, Dornod province, in eastern Mongolia
was of the highest content 58.55 mg/g. The contents of three flavanone constituents (liquiritin apioside, liquiritin and liquiritigenin)
and three chalcones (isoliquiritin apioside, isoliquiritin and isoliquiritigenin) varied significantly according to collection
places; the subtotal of the three flavanones ranged from 3.00 to 26.35 mg/g, and the subtotal of the three chalcones ranged
from 1.13 to 10.50 mg/g. The content of glycyrrhizin and subtotal contents of flavanones and chalcones in the underground
parts of G. uralensis from Mongolia were obviously lower than wild samples, but higher than cultivated samples derived from the same species produced
in China. Glycycoumarin, a species-specific constituent of G. uralensis, was detected in all Mongolian samples. Its contents in samples from eastern Mongolia, Sergelen and Tamsagiyn hooly of Dornod
province were very high and were compatible with Tohoku-kanzo derived from wild Chinese G. uralensis. The present study suggested that Mongolian G. uralensis could be a source of Glycyrrhizae Radix, mostly of Japanese Pharmacopoeia grade. However, the producing area should be taken
into consideration to ensure relatively high quality. In addition, planned use and promotion of cultivation must be advocated
to avoid confronting Mongolian Glycyrrhiza with the same threat as its congener in China. Our study sheds some light on selecting cultivation areas and superior strains,
which are important tasks to promote cultivation. 相似文献

Fomitopsis officinalis is a medicinal fungus, known as ‘Agarikon’, and is used traditionally in the treatment of asthma and rheumatism in Mongolia. The investigation of the chemical constituents of F. officinalis led to the isolation of 4 new lanostane triterpenoids together with 4 known triterpenoids. Inhibitory activity against Trypanosoma congolense, which causes fatal diseases in animals including livestock, was estimated for the isolated compounds. Compounds 2–5 and 8 exhibited moderate inhibition activities with IC50 values ranging from 7.0?27.1 µM. 相似文献

Suppression of NO production in activated macrophages in vitro and ex vivo by neoandrographolide isolated from Andrographis paniculata 总被引:3,自引:0,他引:3

In this study, we investigated the in vitro and ex vivo suppressive effects of Andrographis paniculata on nitric oxide (NO) production in mouse peritoneal macrophages elicited by bacillus Calmette-Guéin (BCG) and stimulated by lipopolysaccharide (LPS). Incubation of BCG-induced macrophages with the methanol extract of A. paniculata reduced LPS stimulated NO production. The diterpene lactones andrographolide and neoandrographolide were isolated as active components from the extract. These compounds suppressed NO production in a concentration-dependent manner in the concentration range from 0.1 to 100 microM and their IC50 values were 7.9 and 35.5 microM. Neoandrographolide also suppressed NO production by 35 and 40% when the macrophages were collected after oral administration of neoandrographolide at doses of 5 and 25 mg/kg/d and LPS stimulated NO production was examined. However, andrographolide did not reduce NO production on oral administration at the same doses. These results indicate that neoandrographolide, which inhibited NO production both in vitro and ex vivo may play an important role in the use of A. paniculata as an anti-inflammatory crude drug. 相似文献

Mongolian plants were screened for their influence on alpha-amylase activity in mouse plasma. Methanolic extracts of Geranium pratense, Rhodiola rosea, Ribes pullchelum and Vaccinium uliginosum inhibited the enzyme activity in isolated mouse plasma by greater than 40% and the effect was concentration dependent. Vaccinium uliginosum also showed a depressive effect on elevation of postprandial blood glucose to some extent. 相似文献

Ephedrae herba has been used for treating colds, relieving coughs and asthma from ancient times. We previously reported the distribution of Ephedra sinica, E. equisetina, E. przewalskii, E. regeliana, E. monosperma and Ephedra sp. in Mongolia, and among them E. sinica and E. equisetina were potential new resources of Ephedrae herba of Japanese pharmacopoeia grade, based on our field survey and subsequent molecular and chemical assessments. However, the Ephedra population in southwestern areas showed a high possibility of having hybrid origins. Further field surveys in southwestern areas, and sequence analysis of the partial nuclear internal transcribed spacer 1 (ITS1) region, besides trnK and 18S ribosomal RNA (rRNA) gene regions, were conducted in order to obtain detailed evidence of hybridization status. As a result, the distribution of E. glauca in western area and E. lomatolepis in western-most area was confirmed. The ITS sequences from all 8 Ephedra species collected in Mongolia were roughly divided into 5 types (types I-V). Type II sequence, having several additive nucleotides, was found in Ephedra sp., E. glauca, E. regeliana and E. sinica, which provided useful information for tracing hybrid origins. Morphological, genetic and distribution evidence suggested that the hybridization of Ephedra species occurred widely in southwestern Mongolia, and several Ephedra species including E. przewalkskii and E. intermedia were involved in these events. Integrated with our previous report, trnK-, 18S- and ITS-types from pure lines of each species are proposed. In addition, we propose a practicable method for detecting additive peaks on a direct sequencing electropherogram. 相似文献
