To investigate the species of Ligularia distributed in the northwestern China and their medicinal uses in the local area.
Field investigation, specimen collection, taxonomic study and datum check were adopted.
There are 29 species and 1 varieties of Ligularia distributed in the northwestern China, and 18 species of them had been used as folk medicines with the function of resolving phlegm, relieving cough, clearing heat and toxins.
The northwestern China is abundant in medicinal resource of Ligularia.

    • "Nowadays, though G. dahurica Fisch is cultivated in some areas of the northwest of China, it has been not still enough for the large necessaries for the domestic and international markets. Moreover, G. dahurica Fisch is only suitable for growing in a high altitude and cold mountainous area of the northwest of China (Liu et al. 2006). These traits of G. dahurica Fisch have restricted its extended breeding. "

    ABSTRACT: Gentiana dahurica Fisch is one of four important commercial Radix Gentianae stipulated by the Chinese Pharmacopoeia. We have established a rapid and effective regeneration system using zygotic embryo-derived callus of G. dahurica Fisch. Using this regeneration system, Agrobacterium tumefaciens-mediated transformation of G. dahurica Fisch has been developed. Zygotic embryo-derived callus was infected with an A. tumefaciens strain (GV3130) harboring a pBI121 vector that contained an nptII selective marker gene. In a total of 60 zygotic embryo-derived calli assayed, frequency of calli with nptII gene PCR-positive transgenic plantlets is 5%. Transient glucuronidase (GUS) expression was observed from these transgenic plantlets. Frequency of GUS-positive transgenic plantlets (4/78) was approximately consistent with that of PCR assay (3/60). Our data indicate that we have successfully established a stable G. dahurica Fisch transformation system by A. tumefaciens. In general, this transformation system we have established might be useful for modifying physiological, medicinal and horticultural traits.

    ABSTRACT: Five new eremophilane-type sesquiterpenes, 3β-(acetyloxy)-7-hydroxynoreremophila-6,9-dien-8-one (1), 8β-hydroxy-2-dehydroxyliguhodgsonal (2), 3β-(acetyloxy)-11-methoxy-8-oxoeremophila-6,9-dien-12-oic acid (3), 3β-(acetyloxy)-11-(2′-methylbutanoyloxy)-8-oxoeremophila-6,9-dien-12-oic acid (4), and 3β-(acetyloxy)-6α-hydroxyligularenolide (5), along with the three known compounds 6–8, were isolated from the roots of Ligularia przewalskii. The structures of the new compounds were elucidated through spectral studies including HR-EI-MS, IR, and NMR data.

    ABSTRACT: Four new eremophilane-type sesquiterpenes, 3β-(acetyloxy)-6β-(2-methylbutanoyloxy)-10β-hydroxyeremophil-7(11)-en-12,8α-olide (1), 3β-(acetyloxy)-6α,7α-epoxy-11-noreremophil-9(10)-ene-8,11-dione (2), 3β-hydroxy-11-noreremophila-6(7),9(10)-diene-8,11-dione (3), and 3β-(3-methylbutanoyloxy)-11-noroxoeremophila-6(7),9(10)-diene-8,11-dione (4) were isolated from roots of Ligularia japonica. The structures of the new compounds were elucidated through spectral studies including HR-EI-MS, IR, and NMR data.
