pennogenin/paris polyphylla

Paris polyphylla Smith var. yunnanensis, has been used in traditional Chinese medicine for its antibiotic and anti-inflammatory properties; in addition it has been used to cure liver cancer in particular. In this current study, β-ecdysterone (1) and three pennogenin steroidal saponins (2-4) were

Rhizomes of the perennial herb Paris polyphylla have been used in traditional Chinese medicine for hundreds of years. Agricultural production of the rhizomes requires 7-10 years, which is too long to meet the demand of the medicinal industry. Therefore, studies on improving the yield of the herb and

OBJECTIVE To research the steroidal saponins of Paris polyphylla Smith var stenophylla Franch for enriching the resource of Radix Paridis. METHODS Compounds were isolated by silica gel, macroporous adsorption resin,Sephadex LH-20 and RP-C18 column chromatography and the structures were elucidated on

BACKGROUND Total steroidal saponins of Paris polyphylla Sm. var. yunnanensis (TSSP) have been widely used in China for the treatment of abnormal uterine bleeding (AUB). But until now, the main active constituents and the mechanisms underlying the pharmacological actions on uterine activity have not

The methanolic extract from the rhizomes of Paris polyphylla SM. var. yunnanensis (FR.) H-M. was found to potently inhibit ethanol-induced gastric lesions in rats. Through bioassay-guided separation, four known spirostanol-type steroid saponins, pennogenin

BACKGROUND Steroidal saponins have long attracted scientific attention, due to their structural diversity and significant biological activities. For example, total steroidal saponins extracted from the rhizome of Paris polyphylla Sm. var. yunnanensis (TSSPs) constitute an effective treatment for

BACKGROUND Total steroidal saponins extracted from the rhizome of Paris polyphylla Sm. var. yunnanensis (TSSPs) have been demonstrated to promote hemostasis in vivo and induce platelet aggregation in vitro. Pennogenin tetraglycoside (Tg) has been identified as one of the active ingredients in TSSPs

Three steroidal saponins, including one new and two known compounds, were isolated from the rhizomes of Paris polyphylla Smith. One- and two-dimensional NMR, LC-MS, and interpretation of hydrolytic cleavage experiments led to the identification of the structure of the new saponin as (

Pennogenin 3-O-β-D-glucopyranosyl-(1 → 3)-[α-L-rhamnopyranosyl-(1 → 2)]-β-D-glucopyranoside, a monodesmosidic saponin isolated from Paris polyphylla Smith var. yunnanensis with promised antitumor activities, was firstly synthesized from glucoside thiol via nine steps and with 27% overall yield.

BACKGROUND Total steroidal saponins extracted from the rhizome of Paris polyphylla Sm. var. yunnanensis (TSSPs) have been widely used in China for the treatment of abnormal uterine bleeding. We previously studied the main active constituents of TSSPs and their structure-activity relationships with

OBJECTIVE To study the anti-tumor active constituents from the rhizome of Paris polyphylla var. yunnanensis. METHODS The compounds were isolated by column chromatography with silica gel, and purified by Sephadex LH-20 columu chromafography and reverse-phase preparative, HPLC. The structures were

BACKGROUND Chong-lou (Paris polyphylla var. yunnanensis or P. polyphylla var. chinensis) is traditionally used as an anticancer medicine in China. It is also the material basis of some Chinese patent anticancer medicines, such as Gan-Fu-Le capsules, Bo-Er-Ning capsules, Lou-Lian capsules, Ruan-Jian

Colorectal cancer is one of the most common cancers worldwide and chemotherapy is the main approach for the treatment of advanced and recurrent cases. Developing an effective complementary therapy could help to improve tumor suppression efficiency and control adverse effects from chemotherapy.

High performance liquid chromatography coupled with electrospray ionization multi-stage tandem mass spectrometry (HPLC-ESI-MS(n)) and triple quadrupole mass spectrometric detection (HPLC-ESI-MS/MS), respectively, had been employed for the simultaneous identification and quantification of steroidal

OBJECTIVE Total steroidal saponins extracted from the rhizome of Paris polyphylla (TSSP) have been used in China for the treatment of abnormal uterine bleeding. The aim of this study was to analyse the structure-activity relationship of steroidal saponins purified from P. polyphylla Sm. var.
