clematis stans/neoplasms

The plants examined in this study have previous biological activity reports indicating the possibility of found activity against herpes and cancer cell. The aim of this contribution was to carry out a screening of Juglans mollis (Juglandaceae), Persea americana (Lauraceae), Hamelia patens

BACKGROUND Epidermal growth factor receptor (EGFR) is an effective molecular target for cancer treatment. Boehmenan, a lignan from the dried stems of Clematis armandii, exhibited the potent cytotoxic effects against many cancer cell lines in previous studies. However, the effects and underlying

Clematichinenoside AR (AR), a major active ingredient extracted from traditional Chinese herb Clematis chinensis Osbeck, has been demonstrated to possess anti-inflammatory and immune-modulatory activities in the treatment of experimental rheumatoid arthritis (RA). The therapeutic potential of AR was

There is no ethnobotanical study conducted specifically on medicinal plants traditionally used to treat cancer in Ethiopia. Yet, traditional herbalists in different parts of the country claim that they have been treating cancer-like symptoms using herbal remedies. The objective of this study was to

OBJECTIVE To investigate the anti-proliferative effects of saponins prepared from Plena Clematis (PC) cultured in Fujian Province, China on 4 human tumor cell lines and its possible anti-tumor mechanism. METHODS The growth inhibition assays of saponins on human esophageal squamous carcinoma cell

Natural plants offer a treasure trove of resources for anticancer drug development. Clematis are widely used in Traditional Chinese Medicine. However, studies on the active substances in Clematis are scarce. In the present study, four monomer compounds were successfully extracted from this species

Four new oleanane type triterpenoid saponins (1-4) and three known saponins (5-7) were isolated from the whole plant of Clematis lasiandra Maxim. The structures of the four new compounds were elucidated as 3-O-β-D-ribopyranosyl-(1 → 3)-α-L-rhamnopyranosyl-(1 → 2)-[β-D-glucopyranosyl-(1 →

To investigate the chemical constituents of Clematis aethusifolia,a traditional Mongolian medicine for resolving hard lump. Bioactive guided isolation and purification of Clematis aethusifolia was performed by normal and reverse phase column chromatography, Sephadex LH-20 and preparation HPLC. The

Sixteen triterpenoid saponins (1-16) were isolated from the stems of Clematis parviloba, including a new compound, parvilobaside A (1), which was established as 23-O-acetyl-hederagenin-3-O-beta-D-ribopyranosyl-(1 --> 3)-alpha-L-rhamnopyranosyl-(1 --> 2)-alpha-l-arabinopyranoside on the basis of

BACKGROUND The dried stems of Clematis armandii (Caulis clematidis armandii), named "Chuan-Mu-Tong" in Chinese Pharmacopoeia, have been traditionally used as an herbal remedy mainly for inflammation-associated diseases. The Aim of the study is to identify the potential anti-neuroinflammatory

Eight new bisdesmosidic triterpenoid saponins, clematiunicinosides A-H (1-8), along with eleven known ones (9-19), were isolated from the roots of Clematis uncinata. Their structures were elucidated on the basis of spectroscopic analysis and chemical evidence. All the isolated saponins were tested

A new taraxastane-type triterpenoid glycoside, clematiunicinoside I (1), together with four known ones (2-5), was isolated from the roots of Clematis uncinata. The structure of the new compound was elucidated on the basis of spectroscopic analyses and acid hydrolysis. The cytotoxic activities of all

In the course of our search for antitumour constituents from the traditional Mongolian medicinal herb Clematis aethusifolia Turcz., 11 flavonoids were isolated for the first time from the dried aerial parts of the plant by flash C18 column chromatography, Sephadex LH-20 and reversed phase

This paper has shown the cytocidal effects of total saponin of Clermatis chisensis Osbeck (CCS) on experimental tumours EAC cells, S180A cells and HepA cells in vitro, using microculture method 72 hours. The IC50 were 242 micrograms/ml, 193 micrograms/ml and 130 micrograms/ml respectively. In vivo

A saponin-enriched fraction prepared from the MeOH extract of the roots of Clematis chinensis showed cytotoxic activity against HL-60 promyelocytic leukemia cells, from which five new triterpene saponins based on oleanolic acid, along with three known saponins, were isolated. The structures of the
