Two ellagic acids isolated from roots of Sanguisorba officinalis L. promote hematopoietic progenitor cell proliferation and megakaryocyte differentiation.
Using a bioassay-directed chromatographic separation, two ellagic acids were obtained from the ethyl acetate extract of the roots of Sanguisorba officinalis L. On the basis of chemical and spectroscopic methods, the two ellagic acids were identified as 3,3',4-tri-O-methylellagic acid-4'-O-β-d-xyloside and 3,3',4-tri-O-methylellagic acid. Stimulation of cell proliferation was assayed in hematopo...
متن کاملTerpene glycosides from the roots of Sanguisorba officinalis L. and their hemostatic activities.
Guided by a hemostasis bioassay, seven terpene glycosides were isolated from the roots of Sanguisorba officinalis L. by silica gel column chromatography and preparative HPLC. On the grounds of chemical and spectroscopic methods, their structures were identified as citronellol-1-O-α-L-arabinofuranosyl-(1→6)-β-D-glucopyranoside (1), geraniol-1-O-α-L-arabinofuranosyl-(1→6)-β-D-glucopyranoside (2),...
متن کاملIsolation and identification of the phenolic compounds from the roots of Sanguisorba officinalis L. and their antioxidant activities.
Four phenolic compounds were isolated from the roots of Sanguisorba officinalis L. by silica gel column chromatography and preparative HPLC. On the basis of chemical and spectroscopic methods, their structures were identified as methyl 4-O-β-D-glucopyranosy-5-hydroxy-3-methoxylbenzoate (1), 3,3′,4′-tri-O-methylellagic acid (2), fisetinidol-(4α-8)-catechin (3), and (+)-catechin (4). Compound 1 i...
متن کاملHematopoietic stem/progenitor cell commitment to the megakaryocyte lineage.
The classical model of hematopoiesis has long held that hematopoietic stem cells (HSCs) sit at the apex of a developmental hierarchy in which HSCs undergo long-term self-renewal while giving rise to cells of all the blood lineages. In this model, self-renewing HSCs progressively lose the capacity for self-renewal as they transit into short-term self-renewing and multipotent progenitor states, w...
متن کاملThe Effect of Platelet Lysate on Expansion and Differentiation Megakaryocyte Progenitor Cells from Cord Blood CD34+ enriched Cells
Background: Umbilical cord blood hematopoietic stem cells (UCB-HSCs) are an attractive source for transplantation. The generation of megakaryocyte-committed cells could lead to shorten period of thrombocytopenia after HSCs transplantation. Platelet lysate (PL) unlike fetal bovine serum (FBS) can prevent immune problems as well as avert transmission of certain diseases to the recipient. In this ...
