OBJECTIVE
To select the optimum purification process of all tubeimosides from Bolbostemma paniculatum by macroporous resin.
METHODS
Static absorption test and deabsorption test were carried out to screen the best macroporous resin for all tubeimosides. The single factor test, orthogonal experimental
Bolbostemma paniculatum (Maxim.) Franquet (Cucurbitaceae) is a traditional Chinese medicinal plant (1), from which tubeimoside 1 was isolated. The antitumor activity and toxicity of tubeimoside 1 was investigated in vivo and in vitro. The results showed that tubeimoside 1 exerts potent anti-tumor
Malignant glioblastoma is one of the most common malignant tumors in the neurological system. Tubeimoside V (1), a new cyclic bisdesmoside from tubers of Bolbostemma paniculatum, appears to exhibit various biological activities, including antitumor effect, but the function and mechanism of this new
As tubeimoside I isolated from Bolbostemma paniculatum (Maxim.) Franquet (Cucurbitaceae) has been shown to suppress tumor promoter effects, tubeimoside III from the same plant was tested in vitro and in vivo against the action of the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA).
Tubeimoside 1, one of the new triterpenoid saponins from the bulb of Bolbostemma paniculatum (Maxim) Franquet, had an anti-inflammatory effect on mouse ear edema induced by arachidonic acid and 12-O-tetradecanoylphorbol-13-acetate (TPA). Furthermore, a potent anti-tumorigenic effect of tubeimoside 1
Macropinocytosis is a highly conserved endocytic process which characterizes the engulfment of extracellular fluid and its contents into cells via large, heterogeneous vacuoles known as macropinosomes. Tubeimoside-1 (TBM1) is a low toxic triterpenoid saponin extracted from a traditional Chinese herb
OBJECTIVE
To study the method of callus induction and culturing of Bolbostemma paniculatum and its relationship with accumulation of tubeimoside.
METHODS
Stem and leaf were selected as explants. The effects of growth substances and their combinations at different concentrations on callus formation
OBJECTIVE
Tubeimoside, which is composed of tubeimoside I (79%) and II (21%), was isolated from the tubers of Bolbostemma paniculatum (Maxim) Franquet (Cucurbitaceae), a traditional Chinese medicine, "Tu-Bei-Mu". This study was designed to investigate the anti-tumor mechanism of
Tubeimoside I is an important component isolated from Bolbostemma paniculatum. Tubeimoside I has been demonstrated to possess many pharmacological activities, including anti-inflammatory, antitumor, and antitumor-promoting effects. The purpose of the present study was to examine in vivo
Natural products isolated from Chinese medicinal herbs are useful sources of new drugs for cancer therapy. Tubeimoside-1 (TBMS1) is a natural compound isolated from the Chinese medicinal herb Bolbostemma paniculatum (Maxim.) Franquet (Cucurbitaceae). Studies have shown that TBMS1 has anticancer
Tubeimoside-1 (TBMS1) extracted from Bolbostemma paniculatum (Maxim), is a traditional Chinese herb with anticancer potential. It induces apoptosis in a number of human carcinoma cell lines, but the mechanism has remained unclear. In the present study, we investigated the pro-apoptotic activity of
Tubeimosides I, II and III (cyclic bisdesmosides) have been isolated from Chinese cucurbitaceous crude drug Tu-bei-mu, a tuber of Bolbostemma paniculatum (Maxim.) Franquet. Solubilizing effects of these cyclic bisdesmosides on water insoluble or less-soluble compounds were examined. It was revealed
Tubeimoside I (TBMS I), an extract from Chinese herbal medicine Bolbostemma paniculatum (MAXIM.) FRANQUET (Cucurbitaceae) has been shown as a potent anti-tumor agent for a variety of human cancers, but yet to be evaluated for hepatoma that is highly prevalent in Eastern Asian countries including
Type 2 diabetes mellitus is often companied with osteoporosis, a process which involves osteoclast activation. In this study, we found tubeimoside I, a natural compound isolated from the Chinese medicinal herb Bolbostemma paniculatum (Maxim) Franquet (Cucurbitaceae), significantly ameliorated the
