Antifungal activities of seven compounds, taxinine (1), paclitaxel (2), phenylisoserine methyl ester (3), sciadopitysin (4), ginkgetin (5), isorhamnetin (6), and quercetin (7), isolated from the leaves of kyaraboku, Taxus cuspidata var. nana, against five plant pathogenic fungi, Gibberella fujikuroi, Cladosporium cucumeninum, Fusarium oxysporum, Colletotrichum fragariae, and Corynespora cassiicola, were investigated for utilization of extractives from trees of the genus Taxus. Also, the amounts… Expand

Figures and Tables from this paper

New insights into the antifungal activity of Taxus baccata L.
TLDR
High level of antifungal activity of methanolic microstrobili extract is shown, which is significantly stronger in comparison to the inhibition by standard antimycotic solution, considering the emerging multidrug resistance in C. albicans. Expand
Antifungal and antibacterial activities of Taxus wallichiana Zucc
TLDR
In vitro antifungal and antibacterial potential of methanol extract and subsequent fractions obtained after partitioning in organic solvents with variable polarity of the aerial parts of the tree Taxus wallichiana Zucc is evaluated. Expand
Effects of sugar and amino acid supplementation on Aureobasidium pullulans NRRL 58536 antifungal activity against four Aspergillus species
Cultured cell extracts from ten tropical strains of Aureobasidium pullulans were screened for antifungal activity against four pathogenic Aspergillus species (Aspergillus flavus, Aspergillus niger,Expand
Anticancer activity of an extract from needles and twigs of Taxus cuspidata and its synergistic effect as a cocktail with 5-fluorouracil
TLDR
The combinational use of the TC extract with 5-FU displays strong cytotoxic synergy in cancer cells and low cytotoxicity in normal cells, suggesting that this cocktail may have a potential role in cancer treatment. Expand
The polar neutral and basic taxoids isolated from needles and twigs of Taxus cuspidata and their biological activity
TLDR
The result of primary screening based on 39 human cancer cell lines suggests that taxinine NN-1 belongs to a new mechanistic class and is a new anticancer agents. Expand
Isolation of Aureobasidium pullulans from bathroom surfaces and their antifungal activity against some Aspergilli
TLDR
From TLC analysis, an antifungal compound with an identical Rf to that of aureobasidin A was found in all extracts and supported the paper disc diffusion and conidial germination inhibition assays. Expand
Application of direct PCR in a forensic case of yew poisoning
TLDR
A novel direct PCR assay for the detection of DNA traces from Taxus spp. Expand
Anticonvulsant, analgesic and antipyretic activities of Taxus wallichiana Zucc.
TLDR
The observed pharmacological activities of the methanol leaf extract provide the scientific basis for the folkloric use of the plant in treating epilepsy, pyrexia and acute pain. Expand
Ethnomedical Properties of Taxus Wallichiana Zucc. (Himalayan Yew)
TLDR
This work focuses on the importance in traditional medicine for its multiple medicinal properties of taxus wallichiana Zucc, a medium-sized, temperate, Himalayan forest tree of medicinal importance in India. Expand

Taxol on the surface of leaves and inside the needles of three species and two varieties of Taxus.
TLDR
Renewable resources of taxol were found both within and on the leaf surface of different Taxus species, the highest taxol concentrations were found to be in the T. media hybrids, higher than in the case of both original species. Expand
Isolation of phenylisoserine methyl ester from the leaves of Taxus cuspidata var. nana
From methanolic extracts of leaves of kyaraboku, Taxus cuspidata var. nana, phenylisoserine methyl ester (3) was isolated along with taxinine (1), taxol (2), sciadopitysin (4), ginkgetin (5),Expand
Taxus spp. needles contain amounts of taxol comparable to the bark of Taxus brevifolia: analysis and isolation.
TLDR
Taxus needles may provide a renewable source of this valuable compound taxol and 10-deacetylbaccatin III, a related compound that can be converted to taxol through a semi-synthetic route. Expand
Antifungal properties of taxol and various analogues
The antimitotic agent taxol was tested for toxicity towards fungi from different taxonomic groups and found to be particularly active against oomycete fungi. In germinating zoospore cysts of theExpand
Why the yew tree (Taxus Baccata) is not attacked by insects
Abstract In recent years, the yew tree has attracted considerable attention due to the isolation from it of the important antitumour drug Taxol ® . The fact that the wood is not attacked by woodwormExpand
Seasonal changes in the concentrations of four taxoids in Taxus baccata L. during the autumn-spring period.
TLDR
Results confirm that epigenetic factors--date of collection (and thus phyllogenesis and kind of plant tissue--determine taxoid levels during the late autumn-spring period in T. baccata and suggest a possible role for 10-DAB III in the biosynthetic pathway to cephalomannine, a less polar taxoid with a side-chain at position C-13.
