Antiviral activities of purified compounds from Youngia japonica (L.) DC (Asteraceae, Compositae)

Tanacetum vulgare: antiherpes virus activity of crude extract and the purified compound parthenolide

“…Medicinal plants with potential antiviral activity have been widely studied with promising results. Several members of the family Asteraceae have shown antiviral activity against all sorts of viruses (Robin et al, 2001;Bettega et al, 2004;Ooi et al, 2006 (1); untreated infected cell (2); infected cells treated with 1 μg/mL (3); 1.5 μg/mL (4); 2 μg/mL (5); 2.5 μg/mL of parthenolide (6). et al, 2006).…”

Identification of the phenolic components of chrysanthemum flower (Chrysanthemum morifolium Ramat)

“…Among them, acacetin 7-O-galactoside and apigenin 7-O-beta-D-(4"-caffeoyl) glucuronide were isolated as the anti-HIV compounds of this herb (Hu, Chen, Shi, Kilkuskie, Cheng, & Lee, 1994;Lee, Kim, & Lee, 2003). Chlorogenic acid, 3,5-, 1,5-and 4,5-di-caffeoylquinic acids, luteolin 7-O-glucoside and luteolin-7-O-glucuronide demonstrate a variety of biological characteristics, such as radical-scavenging and antioxidant, anti-inflammatory, anti-virus, anti-HIV, anti-mutagenic, anti-carcinogenic, anti-hepatotoxic, and antiaging activities that are considered beneficial to human health (Kurata, Adachi, Yamakawa, & Yoshimoto, 2007;Manach, Scalbert, Morand, Remesy, & Jimenez, 2004;Yoshimoto, Yahara, Okuno, Islam, Ishiguro, & Yamakawa, 2002;Ooi, Wang, He, & Ooi, 2006;Parejo, Caprai, Bastida, Viladomat, Já uregui & Codina, 2004).…”

Purification and identification of antiviral components from Laggera pterodonta by high-speed counter-current chromatography

“…Based on thin-layer chromatography (TLC), UV and HPLC analysis, it indicated that the aqueous extract of L. pterodonta was rich in phenolic compounds, and three dicaffeoylquinic acids were the main compounds [9]. Recent studies have showed that dicaffeoylquinic acids had potent antiviral activity [10][11][12]. So, further studies on pharmacological and clinical effects necessitate the development of an efficient preparative separation method of these three main compounds.…”
