RESUMO
Ferula sinkiangensis K.M. Shen is a kind of endangered national plant medicine in the northern of Xinjiang,China. It mainly contains sesquiterpene coumarins,sulfides,polysaccharides,aromatic compounds and other effective chemical constitu-tions;Chromatography is used to build the fingerprint and to control the medicine quality in most cases. Both raw plant medicine and specific compounds possess pharmacologic activities such as antibacterial,insecticidal,anti-allergic,and antitumor properties. The present paper summarizes the resource distribution,chemical constituents,fingerprints and pharmacological activities of F. sinkian-gensis,to provide reference for its systematic research,effective quality control and efficient development and utilization.
RESUMO
Objective To establish a high-throughput detection of medicine on DPPH free radical scavenging activity;To analyze and preliminarily screen the anti-oxidant activity part of Ferula sinkiangensis. Methods Taking DPPH free radical scavenging rate of ascorbic acid as positive control, and IC50 as the evaluating criterion of DPPH free radical scavenging capability, oxidation resistance of different polar parts (petroleum ether part, ethyl acetate part, methyl alcohol part, and water part) of Ferula sinkiangensis was evaluated and screened. Results Different polarity parts of Ferula sinkiangensis DPPH radical scavenging of IC50 were:petroleum ether part 3252.22 μg/mL, ethyl acetate part 36.22 μg/mL, methyl alcohol part 32.22 μg/mL, water part 2643.38 μg/mL, and positive control group ascorbic acid 27.16 μg/mL. Conclusion The ethyl acetate and methyl alcohol parts of Ferula sinkiangensis were effective anti-oxidant activity site to eliminate DPPH free radicals. In this study, a simple, sensitive, and high-throughput detection method of DPPH radical scavenging assay was established to provide reference for the anti-oxidation medicine detection screening.
RESUMO
Objective: To study the chemical constitutions from the seeds of Ferula sinkiangensis. Methods: Using different chromatographic methods to isolate and purify the compounds and to identify their structures by physicochemical properties and spectroscopic technology. Results: Thirty-two compounds were isolated and elucidated as butanedioic acid (1), variecolorquinonesa (2), β-sitosterol (3), stigmasterol-3-O-glucoside (4), 1-(3-ethylphenyl)-1,2-ethanediol (5), pinoresinol (6), (7,8-cis-8,8'-trans)- 2',4'-dihydroxyl-3,5-dimethoxy-lariciresinol (7), secoisolariciresinol (8), n-hexacosanol (9), isoquercitrin (10), quercetin (11), ferulic acid (12), stigmasterol (13), luteolin-7-O-β-D-gluronide (14), (R)-2'-hydroxy-N-[(2S,3S,4R)-1,3,4-trihydroxyhexacosan-2-yl] nonadanamide (15), macrathoinf (16), 1,5-di-O-caffeoylquinic (17), arctiin (18), parvifoliolsg (19), 5-hydroxymethyl fufural (20), daucosterol (21), vanillic acid (22), sucrose (23), rutin (24), neoarctina (25), methyl chlorogenate (26), 5-O-caffeoylquinic (27), uridine (28), inosine (29), 7-hydroxy coumarin (30), chlorogenic acid (31), and caffeic acid (32). Conclusion: Compounds 2, 5-11, 14-20, 22, 24-29, 31, and 32 are isolated from the plants of Ferula L. for the first time.
RESUMO
AIM:To establish a qualitative fingerprint analysis with capillary GC. METHODS:HP-INNOWAX column(30 m?0.53 mm,1.0 ?m),column temperature:90 ℃(15 min)4 ℃/min180 ℃(5 min)2 ℃/min200 ℃(3 min)10 ℃/min220 ℃(5 min),FID detector temperature:230 ℃. RESULTS:Compared with reference peak of Sec-butyl-cis/trans-1-propentyl disulfide,17 common peaks on fingerprints of the oil from ferula sinkiangensis K.M.Shen were indicated by the method with satisfied stability,precision and repeatability. CONCLUSION:There are good similarities among 10 batches of essential oil from Ferula sinkiangensis K.M.Shen,and this method is reliable,simple and provides a reference standard for the quality control of Ferula sinkiangensis K.M.Shen.
