Background:Pistacia chinensis Bunge has been traditionally used to manage various conditions,including asthma,pain,inflammation,hepatoprotection,and *** study was conducted to investigate the antioxidant and anti-lipoxygenase(LOX)properties of the isolated compound 2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-4H-chromen-4-one from Pistacia ***:LOX assay and antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl(DPPH)assay were *** docking studies were conducted using a molecular operating ***:The LOX assay revealed significant inhibitory effects at 0.2µM concentration,with an IC50 value of 37.80µ*** antioxidant effect demonstrated dose-dependency across 5 to 100µg/mL concentrations,reaching 93.09%at 100µg/mL,comparable to ascorbic acid’s 95.43%*** docking studies highlighted strong interactions with the lipoxygenase enzyme,presenting an excellent docking score of-10.98 kcal/***:These findings provide valuable insights into Pistacia chinensis’chemical components and biological effects,reinforcing its traditional medicinal applications.

作者： saima naz Muhammad Asif Hanif Tariq Mahmood Ansari Jamal Nasar Al-Sabahi Institute of Chemical Sciences Bahauddin Zakariya University Department of Chemistry University of AgricultureFaisalabad Department of Petroleum and Chemical Engineering Sultan Qaboos University

A comparative study of Cannabis sativa(Hemp)essential constituents obtained by using Supercritical Fluid Extraction(SCFE),Steam Distillation(SD)and Hydrodistillation(HD)is presented *** optimized extraction temperatures were 130,110and 50℃for hydrodistillation,steam distillation and supercritical fluid extraction *** essential oil of *** was analyzed by using Gas chromatography mass spectrometry(GC-MS).A total of 33,30and 31components have been identified in HD,SD and SCFE *** of essential oil using SCFE(0.039%)was more than HD(0.025%)and SD(0.035%)extraction *** main component of sesquiterpenes obtained by hydrodistillation at 130℃with their percentages included caryophyllene(40.58%),trans-α-bergamotene(5.41%),humulene(10.97%),cis-β-farnesene(8.53%)and monoterpenes includedα-pinene(2.13%),d-limonene(6.46%),p-cymol(0.65%)and cineole(2.58%)*** main component of sesquiterpenes obtained by SD steam distillation at110℃including caryophyllene(38.60%)trans-α-bergamotene(4.22%),humulene(10.26%),cis-β-farnesene(6.67%)and monoterpenes includedα-pinene(3.21%),d-limonene(7.07%),p-cymol(2.59%)and cineole(3.88%)whereas the more percentages of major components were obtained by SCFE at 50℃included caryophyllene(44.31%),trans-α-bergamotene(6.79%),humulene(11.97%)cis-β-farnesene(9.71%)and monoterpenes includedα-pinene(0.45%),d-limonene(2.13%)p-cymol(0.19%)and cineole(1.38%)*** found yield/efficiency,chemical composition,quality of the essential oils by supercritical fluid extraction superior in terms of modern,green,saving energy and a rapid approach as compared to traditional techniques.

目的探讨脂肪酸结合蛋白和脂肪酸合成酶与乳腺浸润性导管癌发生发展的关系及作用机制,以探询新的分子标志和早期分子治疗的靶基因。方法用半定量逆转录聚合酶链反应、免疫组织化学和Westernblot等方法检测表皮型脂肪酸结合蛋白(E-FABP)和脂肪酸合成酶(FAS)在76例浸润性乳腺导管癌中的表达变化。结果E-FABP广泛分布于浸润性导管癌的血管内皮细胞、导管和腺泡的上皮细胞,mRNA和蛋白质的表达量在III级浸润性导管癌的较I、II级明显下调(P0.05)。结论在I、II级浸润性导管癌,E-FABP可能作为FAS的下游分子,结合和转运FAS合成的长链脂肪酸,以维持肿瘤细胞旺盛的代谢;在III级导管癌,E-FABP、FAS的表达明显下调,癌细胞的活动可能有赖于其他信号分子起作用。本研究为进一步探寻浸润性乳腺导管癌的分子标志及早期治疗途径提供理论依据。
