Abstract
Androgen is a kind of steroid hormone that plays a vital role in reproductive system and homeostasis of the body. Disrupted androgen balance serves as the causal contributor to a series of physiological disorders and even diseases. Flavonoids, as an extremely frequent family of natural polyphenols, exist widely in plants and foods and have received great attention when considering their inevitable consumption and estrogen-like effects. Mounting evidence illustrates that flavonoids have a propensity to interfere with androgen synthesis and metabolism, and also have a designated improvement effect on androgen disorders. Therefore, flavonoids were divided into six subclasses based on the structural feature in this paper, and the literature about their effects on androgens published in the past ten years was summarized. It could be concluded that flavonoids have the potential to regulate androgen levels and biological effects, mainly by interfering with the hypothalamic-pituitary-gonadal axis, androgen synthesis and metabolism, androgen binding with its receptors and membrane receptors, and antioxidant effects. The faced challenges about androgen regulation by flavonoids masterly include target mechanism exploration, individual heterogeneity, food matrixes interaction, and lack of clinical study. This review also provides a scientific basis for nutritional intervention using flavonoids to improve androgen disorder symptoms.

Apigenin, flavonoid component isolated from Gentiana veitchiorum flower suppresses the oxidative stress through LDLR-LCAT signaling pathway. Biomed Pharmacother 2020; 128:110298. [PMID: 32504920 DOI: 10.1016/j.biopha.2020.110298] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 05/17/2020] [Accepted: 05/19/2020] [Indexed: 01/17/2023] Open
Abstract
Flower of Gentiana veitchiorum has traditionally been used as an herbal medicine in Tibet for treatment of variola, respiratory infection, and pneumonia. However, the effective components contained in flower are not identified yet, and the underlying mechanisms for anti-inflammatory, antibacterial, and antioxidative activities remain to be elucidated. Here, we first extracted the flavonoid mixture from G. veitchiorum flower. The mixture was then further isolated and the within compounds was identified through the high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). The results showed that apigenin (4',5,7-trihydroxyflavone) was the most abundant flavonoid in G. veitchiorum flower. We next examined the antioxidative activity of the extracted apigenin using the ferric reducing/antioxidant power (FRAP), the 1,1-diphenyl-2-picrylhydrazyl (DPPH), and the 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) assays and found that a positive correlation between apigenin concentration and reactive oxygen species (ROS) scavenging rate. The biochemical assays further revealed that the levels of total cholesterol (TC), triglyceride (TG), and malondialdehyde (MDA) were reduced, while the activity of superoxide dismutase (SOD) was increased after apigenin treatment in hyperlipidemic rats. Moreover, we performed histopathological investigations and found that the lipidic deposition patterns were recovered and the amount of lipid vacuoles was significantly reduced in apigenin-treated hyperlipidemic rat liver. Western blotting assay showed that the expression of low-density lipoprotein receptor (LDLR) and lecithin-cholesterol acyltransferase (LCAT) were up-regulated in the apigenin-treated samples. Overall, our results demonstrated that the apigenin isolated from G. veitchiorum flower exhibited radical scavenging activities, and reversed the high fat diet-induced oxidative damage in rats. Its antioxidative activities are probably achieved via LDLR-LCAT signaling pathway.
