| induction of cytotoxicity of peritoneal exudate cells by agrimoniin, a novel immunomodulatory tannin of agrimonia pilosa ledeb. | the cytotoxic activities of the pec after an i.p. injection of agrimoniin, a tannin contained in agrimonia pilosa ledeb. were studied. the plastic nonadherent pec had significantly higher nk cell activity than the untreated control, and the adherent pec were cytostatic toward mm2 and mh134 cells. the adherent pec did not cause tumor cell lysis by themselves, but were cytolytic against mm2 cells in the presence of anti-mm2 sera. in the course of these effects of pec after the i.p. injection of ag ... | 1988 | 3396026 |
| antitumor effect of agrimoniin, a tannin of agrimonia pilosa ledeb., on transplantable rodent tumors. | the effect of agrimoniin, a tannin contained in agrimonia pilosa ledeb., on ascites type and solid type rodent tumors was investigated. when agrimoniin was intraperitoneally (i.p.) administered at dosages over 10 mg/kg before or after the mm2 cell i.p. inoculation, this tannin almost completely rejected the tumor growth in the mice. this tannin prolonged the life span of mice bearing mm2 or cured by the intravenous or per oral pre- or postmedication. agrimoniin also inhibited the growth of mh134 ... | 1987 | 3573425 |
| effect of hsien-ho-t'sao (agrimonia pilosa) on experimental thrombosis in mice. | the water extract of hsien-ho-t'sao (hht) prolonged the tail bleeding time in conscious mice. this antihemostatic effect was dose-dependent and exhibited a biphasic pattern; i.e. its activity declined at doses higher than 0.5 mg/kg. the prolonged bleeding time persisted for at least 12 hr and maximal effect was observed at 3 hr after the oral administration of hht 500 mg/kg. hht was effective in preventing adp-induced acute pulmonary thromboembolic death in mice, while aspirin and indomethacin h ... | 1987 | 3687839 |
| antitumor activity of methanol extract from roots of agrimonia pilosa ledeb. | to evaluate the antitumor activity of agrimonia pilosa ledeb., the effects of the methanol extract from roots of the plant (ap-m) on several transplantable rodent tumors were investigated. ap-m significantly prolonged the life span of s180-, meth-a fibrosarcoma- and mm-2 mammary carcinoma-bearing mice by intraperitoneal (i.p.) pre- or postmedication. ap-m also inhibited the growth of s-180 solid type tumor. on the other hand, the prolongation of life span induced by ap-m on s-180 ascites type tu ... | 1985 | 4040585 |

| [experimental study on decoctum agrimonia pilosa ledeb-induced apoptosis in hl-60 cells in vitro]. | in this study, mtt assay, cell morphology and flow cytometry were used to explore agrimonia pilosa ledeb on hl-60 cells in vitro. the data suggested that agrimonia pilosa ledeb had the effects of growth inhibition in hl-60 cells. after treated with decoctum agrimonia pilosa ledeb, cells underwent apoptosis with typical morphological feature. dna histograms by flow cytometric analysis displayed distinct apoptotic peak. | 2000 | 12575284 |
| [determination of trace elements in several hemostatic medicinal plants and their boiling water extracts]. | the experimental results indicate that the amounts of cu, zn, fe and mn in rubia cordifolia and agrimonia pilosa var. japonica are very small in boiling water extracts (only 6%). but after digestion they may rise to 30%. it was found that the amounts of four trace elements decreased with the increase of extracting time, but the ratios of mn/zn and zn/cu were almost the same. | 1993 | 8216788 |
| [studies on the structure of a new flavanonol glucoside of the root-sprouts of agrimonia pilosa ledeb]. | three compounds were isolated from benzene and acetone extracts of the root-sprouts of agrimonia pilosa ledeb. on the basis of physicochemical properties, spectroscopy (uv, ir, nmr, ms, cd, gc) and chemical degradation, two known compounds were identified as palmitic acid (viii) and daucosterol (ix), one new compound was elucidated as (2s,3s)-(-)-taxifolin-3-o-beta-d-glucopyranoside (x). | 1990 | 2281787 |
| [studies on the structure of a new ellagic acid glycoside from the root-sprouts of agrimonia pilosa ledeb]. | four compounds were isolated from the root-sprouts of agrimonia pilosa ledeb. on the basis of physico-chemical properties, spectroscopy (uv, ir, nmr, ms) and chemical degradation, a new compound was elucidated as ellagic acid-4-o-beta-d-xylopyranoside (xv), and three known compounds were identified as agrimonolide (xiii), tormentic acid (xiv), and ellagic acid (xvi). | 1990 | 2099598 |
