| succession patterns of fungi associated to wound-induced agarwood in wild aquilaria malaccensis revealed from quantitative pcr assay. | aquilaria malaccensis produces agarwood in response to wounding and fungal attack. however, information is limited regarding aquilaria's interaction with its diverse fungal community. in this study, time-related changes of three natural fungal colonizers in two wounded wild a. malaccensis were tracked, beginning a few hours after wounding up to 12 months. using species-specific primers derived from their nrits sequences in quantitative real-time pcr (qpcr), we quantified the amount of cunningham ... | 2014 | 24840100 |
| antitrypanosomal screening and cytotoxic effects of selected medicinal plants. | trypanosoma evansi, the causative agent of "surra", infects many species of wild and domestic animals worldwide. in the current study, the aqueous and ethanolic extracts of six medicinal plants, namely, aquilaria malaccensis, derris elliptica, garcinia hombroniana, goniothalamus umbrosus, nigella sativa, and strobilanthes crispus were screened in vitro for activity against t. evansi. the cytotoxic activity of the extracts was evaluated on green monkey kidney (vero) cells using mtt-cell prolifera ... | 2014 | 24862048 |
| chemometric analysis reveals links in the formation of fragrant bio-molecules during agarwood (aquilaria malaccensis) and fungal interactions. | fragrant agarwood, arguably the costliest wood in the world, is formed by plant-fungal interactions in aquilaria spp. however, very little is known about this fragrant outcome of interaction. therefore, mimicking the ancient traditions of agarwood production in assam (northeast india), a chemometric assessment of the agarwood-fungus interaction was made by chemical profiling (gc-ms) coupled with statistical analysis (principal component, correlation network analysis) across three platforms, viz. ... | 2017 | 28290512 |
| antiallergic phorbol ester from the seeds of aquilaria malaccensis. | the aquilaria malaccensis (thymelaeaceae) tree is a source of precious fragrant resin, called agarwood, which is widely used in traditional medicines in east asia against diseases such as asthma. in our continuous search for active natural products, a. malaccensis seeds ethanolic extract demonstrated antiallergic effect with an ic50 value less than 1 µg/ml. therefore, the present research aimed to purify and identify the antiallergic principle of a. malaccensis through a bioactivity-guided fract ... | 2016 | 27007372 |
| genetic diversity and population structure of endangered aquilaria malaccensis revealed potential for future conservation. | the endangered aquilaria malaccensis,is an important plant with high economic values. characterization of genetic diversity and population structure is receiving tremendous attention for effective conservation of genetic resources. considering important repositories of biological diversity, the genetic relationships of 127 a. malaccensis accessions from 10 home gardens of three states of northeast india were assessed using amplified fragment length polymorphism (aflp). of the 1153 fragments ampl ... | 2015 | 26690525 |
| evaluation of comprehensive two-dimensional gas chromatography with accurate mass time-of-flight mass spectrometry for the metabolic profiling of plant-fungus interaction in aquilaria malaccensis. | to explore the possible obligate interactions between the phytopathogenic fungus and aquilaria malaccensis which result in generation of a complex array of secondary metabolites, we describe a comprehensive two-dimensional gas chromatography (gc × gc) method, coupled to accurate mass time-of-flight mass spectrometry (tofms) for the untargeted and comprehensive metabolic profiling of essential oils from naturally infected a. malaccensis trees. a polar/non-polar column configuration was employed, ... | 2015 | 25704770 |
| hepatoprotective herbs, avicenna viewpoint. | liver injury or dysfunction is considered as a serious health problem. the available synthetic drugs to treat liver disorders are expensive and cause further damage. hence, hepatoprotective effects of some herbal drugs have been investigated, and one of the methods to choose herbs in order to study their biological effects is to search in ancient medical texts. avicenna who is known as the prince of physicians had collected and classified greek, persian and islamic medicine in the best possible ... | 2014 | 24719702 |
| isolation and characterization of microsatellite markers for an important tropical tree, aquilaria malaccensis (thymelaeaceae). | aggressive collections and trade activities in recent decades have resulted in heavy pressure on the natural stands of aquilaria malaccensis and concerns over its long-term survival potential. to aid dna profiling and assessment of its genetic diversity, microsatellite markers were developed for the species. | 2012 | 23108468 |
| chemical composition of volatile oils of aquilaria malaccensis (thymelaeaceae) from malaysia. | volatile oils of aquilaria malaccensis benth. (thymelaeaceae) from malaysia were obtained by hydrodistillation and subjected to detailed gc-fid and gc/ms analyses to determine possible similarities and differences in their chemical composition in comparison with the commercial oil. a total of thirty-one compounds were identified compared with twenty-nine identified in the commercial oil. the major compounds identified were 4-phenyl-2-butanone (32.1%), jinkoh-eremol (6.5%) and alpha-guaiene (5.8% ... | 2010 | 21299133 |
| effects of agarwood extracts on the central nervous system in mice. | agarwood (jinkoh in japanese) is an oriental medicine for use as a sedative. neuropharmacological studies have been conducted with the extracts of petroleum ether, benzene, chloroform, and water from agarwood (aquilaria sp.; probably aquilaria malaccensis benth.) in mice. the benzene extract showed a reducing effect in spontaneous motility, a prolonging effect on hexobarbiturate-induced sleeping time, a hypothermic effect in terms of rectal temperature, and a suppressive effect on acetic acid-wr ... | 1993 | 8441779 |
| plant anticancer agents. xix constituents of aquilaria malaccensis. | the stem bark of the thai tree aquilaria malaccensis (thymelaeaceae) has afforded 1,3-dibehenyl-2-ferulyl glyceride (3), which is novel, and 12-o-n-deca- 2, 4, 6-trienoylphorbol-13-acetate (4). the structures of these cytotoxic compounds were elucidated by their spectral and chemical parameters. | 2014 | 7320738 |
