RESUMEN

Fibrosis-related diseases (FRD) include conditions like myocardial fibrosis, pulmonary fibrosis, hepatic fibrosis, renal fibrosis, and others. The impact of fibrosis can be severe, causing organ dysfunction, reduced functionality, and even organ failure, leading to significant health issues. Currently, there is a lack of effective modern anti-fibrosis drugs in clinical practice. However, Chinese medicine has a certain beneficial effect on the treatment of such diseases. Angelica sinensis, with its considerable medicinal value, has garnered attention for its anti-fibrosis properties in recent investigations. In the past few years, there has been a growing number of experimental inquiries into the impact of angelica polysaccharide (ASP), angelica water extract, angelica injection, and angelica compound preparation on fibrosis-associated ailments, piquing the interest of researchers. This paper aims to consolidate recent advances in the study of Angelica sinensis for the treatment of fibrosis-related disorders, offering insights for prospective investigations. Literature retrieval included core electronic databases, including Baidu Literature, CNKI, Google-Scholar, PubMed, and Web of Science. The applied search utilized specified keywords to extract relevant information on the pharmacological and phytochemical attributes of plants. The investigation revealed that Angelica sinensis has the potential to impede the advancement of fibrotic diseases by modulating inflammation, oxidative stress, immune responses, and metabolism. ASP, Angelica sinensis extract, Angelica sinensis injection, and Angelica sinensis compound preparation were extensively examined and discussed. These constituents demonstrated significant anti-fibrosis activity. In essence, this review seeks to gain a profound understanding of the role of Angelica sinensis in treating fiber-related diseases. Organ fibrosis manifests in nearly all tissues and organs, posing a critical challenge to global public health due to its widespread occurrence, challenging early diagnosis, and unfavorable prognosis. Despite its prevalence, therapeutic options are limited, and their efficacy is constrained. Over the past few years, numerous studies have explored the protective effects of traditional Chinese medicine on organ fibrosis, with Angelica sinensis standing out as a multifunctional natural remedy. This paper provides a review of organ fibrosis pathogenesis and summarizes the recent two decades' progress in treating fibrosis in various organs such as the liver, lung, kidney, and heart. The review highlights the modulation of relevant signaling pathways through multiple targets and channels by the effective components of Angelica sinensis, whether used as a single medicine or in compound prescriptions.

RESUMEN

OBJECTIVE: To study the chemical constituents from the leaves of "Chuju" Chrysanthemum morifolium. METHODS: All compounds were separated and purified by column chromatography over silica gel, Sephadex LH-20 and preparative HPLC. Their structures were identified by spectral methods including 1H-NMR and 13C-NMR. RESULTS: 21 compounds were isolated and identified as octa-cosyl alcohol (1), ß-sitosterol (2), lupeol (3), α-amyrin (4), daucosterol (5), ineupatorolide B (6), syringin (7), chlorogenic acid (8), petasiphenol (9), physcion (10), acacetin (11), eupatilin (12), quercetin (13), diosmetin (14), luteolin (15), apigenin (16), apigenin- 7-O-ß-D-glucopyranoside (17), quercetin-3-O-ß-D-glucopyranoside (18), luteolin-7-O-ß-D-gluco pyranoside (19), apigenin-7-O-ß-D- neospheroside (20), and acacetin-7-O-ß-D-glucoside (21). CONCLUSION: Compounds 1-12, 18 and 20 are isolated from this plant for the first time. Compounds 10, 13, 14, 15 and 16 have shown strong antioxidant activities by DPPH · scavenging activity better than Vit C.

RESUMEN

High-resolution electrospray ionization multistage tandem mass spectrometry (MS(1-7)) in positive ion mode was used to determine the accurate masses and the fragmentation pathways of two furofurans, sesamin and gmelinol. The protonated molecules [M+H]+ were absent in the conventional mass spectra of both compounds, but two characteristic ions, [M+H-H(2)O]+ and [M+H-H(2)]+, were always observed. Successive losses of CH(2)O and CO are the common characteristic fragmentations. Based on the exact masses acquired from 21 different tandem mass spectra, two or three fragmentation pathways for each compound are proposed. The consecutive losses of two H(2)O molecules and one H(2) molecule readily take place from the furan rings for both sesamin and gmelinol, resulting in the absence of the protonated molecules in the single-stage experiments. HCHO loss is observed at least three times in the tandem mass spectra, mainly from methylenedioxy groups (OCH(2)O) for sesamin but only from tetrahydrofuran rings for gmelinol. Moreover, CO loss is found at least three times in the tandem mass spectra of both sesamin and gmelinol from the 3,4-methylenedioxyphenyl (ArOCH(2)O) moieties for sesamin and from both the dimethoxyphenyl and the tetrahydrofuran ring moieties for gmelinol. In addition, the disubstituted benzyl cation ArCH(2)+ at m/z 135 for sesamin and at m/z 151 for gmelinol was found in the MS(3) spectra of both sesamin and gmelinol, which is very helpful in the identification of the compositions of 3,4-disubstituted groups on the benzene rings of the furofurans.
