OBJECTIVE To determine the anti-inflflammatory effects of an ethanol fraction of Periploca forrestii Schltr. (EFPF) and to investigate the potential mechanisms underlying in vivo and in vitro models. METHODS The antiinflflammatory effects of EFPF were evaluated using the xylene-induced mouse ear

BACKGROUND Periploca forrestii Schltr. is a classical traditional Chinese medicine (TCM) called Heilonggu (HLG) in China. According to the theory of TCM, it possesses the efficacy of eliminating wind and removing dampness. In clinical practice, it is commonly used for the treatment of rheumatoid

OBJECTIVE To investigate the chemical constituents of the roots of Periploca forrestii and evaluate their cytotoxicity activities. METHODS Silica gel column chromatography was employed for the isolation and purification of chemical constituents. The structures were identified on the basis of

The CHCl₃ fraction of MeOH extract of Periploca somaliensis (family Asclepiadaceae) fruits afforded a new scalarane sesterterpene, namely perisomalien A (1), along with lupeol acetate (2), β-amyrin (3), cycloart-23Z-ene-3β,25-diol (4), and β-sitosterol-3-O-β-D-glucopyranoside (5). Their

Six new cardenolides, periforosides D-E (1-2), periforgenin C (3) and periforosides F-H (4-6), as well as 10 previously identified cardenolides (7-16) were isolated from the ethanol extract of the stems of Periploca forrestii. The structures of the new compounds were determined using extensive

Many anticancer drugs are obtained from natural sources. Nature produces a variety of toxic compounds, which are often used as anticancer drugs. Up to now, there are at least 120 species of poisonous botanicals, animals and minerals, of which more than half have been found to possess significant

Oleanolic acid (3β-hydroxy-olean-12-en-28-oic acid; OA-01), a pentacyclic triterpene, exhibit a wide range of pharmacological and biological activities. We have isolated oleanolic acid from methanolic extract of Periploca aphylla, collected from surroundings of Karachi in the month of February.

Periplocin, an active and toxic component of the traditional Chinese herbal medicine Periploca sepium Bge, is a cardiac glycoside compound that has been implicated in various clinical accidents. This study investigated the role of transporters in the intestinal absorption and biliary excretion of

Cortex periplocae is the dried root bark of Periploca sepium Bge., a traditional Chinese herb medicine. It contains high amounts of cardiac glycosides. Several cardiac glycosides have been reported to inhibit tumor growth or induce tumor cell apoptosis. We extracted and purified cortex periplocae

Background: Periploca sepium is traditionally used in Chinese medicine to treat particularly rheumatic disorders and as a tonic. Periplocin was found as the most cytotoxic compound of its root bark and induced death receptor mediated

BACKGROUND During a screening of Chinese plants traditionally used for the treatment of cancer and related diseases, extracts of the root bark of Periploca sepium Bunge showed strong cytotoxic activity. OBJECTIVE Isolate and identify cytotoxic compounds from P. sepium and investigate the effects and

Nine cardiotonic steroids, six 17beta-cardenolides (2, 4, 6-9) and three 17alpha-cardenolides (1, 3, 5) have been identified from the chloroform and chloroform-methanol extracts of Periploca graeca L. (Asclepiadaceae) stems. Among these, compound 5, the 17alpha-isomer of periplocin 6, was identified

OBJECTIVE Cardenoliddes are steroid glycosides which are known to exert cardiotonic effects by inhibiting the Na(+)/K(+)-ATPase. Several of these compounds have been shown also to possess anti-tumor potential. The aim of the present work was the characterization of the tumor cell growth inhibition

Periplocymarin, a cardiac glycoside isolated from Periploca sepium (P. sepium) and Periploca graeca (P. graeca), is a potential anti-cancer compound. The aim of the study was to investigate the potential for periplocymarin to interact with P-glycoprotein (P-gp) and to inhibit cytochrome P450s known

In the present study the antioxidant capacity of Periploca hydaspidis was assessed through various in vitro assays and by the hepatoprotective potential on CCl4 induced toxicity in rat. Phytochemical analysis of different extracts of P. hydaspidis indicated existence of various phytochemical
