Ethnic areas of medicinal plants is an important part of traditional Chinese medicine, scientific development and utilization of natural active ingredients, the papers selected three national regions medicinal plants of the chemical composition of the system. Ear of this research material is collected from the floral patterns gold of of Guizhou Kuankuoshui Nature Reserve (Carpesium triste Maxim) grass, the British county of Sichuan full blood grass (Sambucus adnata Wall) grass and Sichuan Liangshan Long wheatgrass (Agrimonia pliosa Ledeb) whole plant. Using a conventional silica gel column chromatography (Silica gel CC), and gel filtration chromatography (Sephadex LH-20 CC), and preparative thin layer chromatography (PTLC), 33 compounds were isolated. Further use of UV, IR, EI-MS, HR-ESI-MS, 1H-NMR, 13C-NMR, and 2D-NMR (in 1H-1HCOSY, HMQC, HMBC) spectroscopy modern literature comparison identified 30 compounds structure, four of which are new compounds. 17 compounds from the floral patterns gold ear dry a full grass methanol extract, four new sesquiterpene lactone compound :1-oxo-5, 7,8,11 αH-eudesm-2, 4 (15 )-dien-8β ,12-olide (1), 4α-hydroxy-9β, 10β-epoxy-1βH, 5,11 αH-guaia-8α ,12-olide (2), 4α-hydroxy-9β, 10β-epoxy- 1βH, 5αH, 11βH-guaia-8α ,12-olide (3), 1α, 3α-dihydroxy-5, 7,8,11 αH-eudesm-4 (15)-en-8β ,12-olide (5). 5 is known sesquiterpene compounds: 4α-Hydroxy-9β, 10β-epoxy-1βH the 5αH-guaia-11 (13)-en-8α ,12-olide (4), granilin (6), eriolin ( 7), 11 (13)-dehydroivaxillin (8), day names fine lactone ketone (9). 5 steroidal alcohols compound: of β-valley steroid alcohols (10), beans steroid alcohols (11), beans steroidal ol-3-O-of β-J-grape glucoside (12), 5α, 8α-ring dioxo -24 (S-) - methylergoline steroidal -6,22 - diene-3β-ol (13) and 5α, 8α-ring dioxo -24 (S) - methyl-ergost -6,9 (11), 22 - triene - 3β-ol (14). 3 glycoside type compound: the β-daucosterol (15) fructose (16) fructose (17). These compounds were isolated from this plant for the first time. Nine compounds were isolated and identified from the methanol extract of the whole plant of blood, full of grass, are seven pentacyclic triterpenoid: ursolic acid (1), oleanolic acid (2), α-fragrant resin alcohol (3) , 13β-hydroxy-11 - the ene - ursolic acid (4), 28 - hydroxy-α-fragrant resin alcohol (5), 2α, 23 - dihydroxy - bear fruit acid (6), 2α, 3α, 23 - three hydroxy - ursolic acid (7), of 1 Lignans 4-O-methyl cedar hormone (8) and β-daucosterol (9), which compounds 3-9 for the first time isolated from the blood, full of grass. 4 sterol is isolated from the 95% ethanol extract of grass agrimony identified respectively stigmastan -5 - ene-3β, 7β-diol (1), stigmastan -5 - ene-3β, 7α- diol (2), stigmasterol-3β, 6α-diol (3) and β-sitosterol alcohol (4). Compounds 1-3 are for the first time isolated from agrimony. Chemical data support the findings of the paper are expected to provide the rational development and utilization of the resources of medicinal plants of China's ethnic minority areas.
