ABSTRACT
Seven aromatic glycosides (1-7), including four phenylethanol glycosides, one phenylmethanol glycoside, one phenylpropane glycoside and one benzoside, were isolated from the methanolic extract of Uighur Medicine Elaeagnus angustifolia flowers. Their structures were elucidated based on the analysis of spectroscopic data (1D, 2D NMR and HR-MS). Compound 1 is a new compound, named as angustifol A. Six known compounds were identified as 2-phenylethyl-O-β-D-glucopyranoside(2), salidroside (3), vanillic acid 4-O-β-D-glucopyranoside(4), vanilloloside (5), (Z)-isoconiferin (6), 2-phenylethyl-6-O-α-L-arabinofuranosyl-β-D-glucopyranoside (7). Compounds 2-7 were isolated from the genus Elaeagnus for the first time. In vitro anti-inflammatory assays revealed that none of these compounds showed good COX inhibitory activities.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the distribution of abnormal hilit syndromes in traditional Uighur medicine (TUM) among human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) patients, and to find out the clinical characteristics of abnormal savda syndrome type HIV/AIDS patients.</p><p><b>METHODS</b>Between June and July in 2012, 307 eligible HIV/AIDS patients from in-patient department and out-patient clinics of Xinjiang Uighur Autonomous Region the Sixth People's Hospital in Urumqi were investigated. TUM syndrome differentiation was performed by a senior TUM physician. Each participant completed a Sign and Symptom Check-List for Persons Living with HIV/AIDS (SSC-HIV) questionnaire. Depression was evaluated by using Hamilton Rating Scale for Depression Questionnaire. Blood specimen was collected from each participant to test the levels of blood chemicals.</p><p><b>RESULTS</b>Of 307 HIV/AIDS patients, 189 (61.6%) were abnormal savda syndrome type, 118 (38.4%) were non-abnormal-savda syndrome type. Mean CD4 counts of abnormal savda syndrome type patients was (227.61±192.93) cells/µL, and the prevalence of anemia, thrombocytopenia, and elevated cystatin C were 49.7%, 28.6%, and 44.7%, which were significantly higher than those in the non-abnormal-savda syndrome type patients (26.3%, 16.0% and 25.0%,P<0.05). In addition, depression (79.9%) and HIV/AIDS-related symptoms such as fatigue (42.3%), back aches (40.7%), lack of appetite (33.9%), night sweats (31.7%) were more common among abnormal savda syndrome patients (P<0.05).</p><p><b>CONCLUSION</b>Abnormal savda syndrome is the dominant syndrome among HIV/AIDS patients, and they present a more sever clinical manifestation.</p>
