Wang W, Li N, Wang J, Chen G, Huang R, Zhao W, Li J, Si Y. Bioactive benzofuran-chalcanes as potential NQO1 inducers from Millettia pulchra (Benth) kurzvar-laxior (Dunn) Z.Wei. PHYTOCHEMISTRY 2016; 131:107-114. [PMID: 27663949 DOI: 10.1016/j.phytochem.2016.09.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/15/2015] [Revised: 09/04/2016] [Accepted: 09/12/2016] [Indexed: 06/06/2023]
Abstract
Five chalcanes ((α'R)-2, α'-dimethoxy-furano-[4″, 5'': 3', 4'] chalcane, (α'R, βR)-2', α', β-trimethoxy-furano-[4″, 5'': 3', 4'] chalcane, (α'S, βR)-2', α', β-trimethoxy-furano-[4″, 5'': 3', 4'] chalcane, (α'R, βR)-2', β-dimethoxy-α'-hydroxyethoxy-furano-[4″, 5'': 3', 4'] chalcane, (α'S, βR)-2', β-dimethoxy-α'-hydroxyethoxy-furano-[4″, 5'': 3', 4'] chalcane) and a flavonoid glycoside (3', 7-dihydroxy-6-methoxy-4', 5'-methylenedioxyisoflavone 6-O-β-D- glucopyranoside), together with 15 known components, were isolated from the leaves of Millettia pulchra (Benth) Kurzvar-laxior (Dunn) Z. Wei, a traditional Zhuang medicine. Their chemical structures were established by extensive analysis of NMR, mass spectrometry and ECD spectra. Furthermore compounds (α'R, βR)-2', β-dimethoxy-α'-hydroxyethoxy-furano-[4″, 5'': 3', 4'] chalcane, (α'S, βR)-2', β-dimethoxy-α'-hydroxyethoxy-furano-[4″, 5'': 3', 4'] chalcane, quercetin, methyl 2-O-β-D-glucopyranosylbenzoate, 6,7-dimethoxy-3',4'-methylenedioxyisoflavone and lyoniresinol were suggested to be potential chemopreventive agents because of their significant activity in inducing NQO1 ([NAD(P)H quinine oxidoreductase 1], a phase II metabolism enzyme).

Chen S, Xu HQ, Zhang J, Wang CX, Liu JQ, Peng LH, Cheng JL, Liu A. A systematic study of the dissolution and relative bioavailability of four ginsenosides in the form of ultrafine granular powder, common powder and traditional pieces of Panax quinquefolius L, in vitro and in beagles. JOURNAL OF ETHNOPHARMACOLOGY 2016; 185:9-16. [PMID: 26976765 DOI: 10.1016/j.jep.2016.03.032] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/14/2015] [Revised: 02/22/2016] [Accepted: 03/11/2016] [Indexed: 06/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Panax quinquefolius L (PQ), also known as American ginseng, has been used as a medicinal herb for thousands of years in the Far East, which was wildly used actively in healing the cardiovascular, endocrine and immune systems, in supporting chemoprevention of cancer. MATERIALS AND METHODS An integrated, rapid, sensitive and reliable UHPLC-ESI-QQQ MS/MS method was validated and successfully applied in a pharmacokinetics study in which four representative ginsenosides were measured in beagle plasma following oral administration of Panax quinquefolius L (PQ) in the form of ultrafine granular powder, standard powder and an extract. RESULTS Two paired ions ([M+Na](+) in the positive MS process, and two characteristic ions [Q3](+) in the positive MS/MS process) of the target compounds were optimized and selected for improved qualitative and quantitative analysis of ginsenosides in beagle plasma. The relative bioavailability of the target ginsenosides in these three formulations was measured by the pharmacokinetic parameters, including Cmax, Tmax, AUC0-∞ and so on. The ultrafine granular powder had the highest bioavailability, as well as the greatest extent of and fastest dissolution in vitro. CONCLUSION Our results show that improved formulations of PQ could facilitate the dissolution and promote absorption of the important compounds it contains.
