yuehchukene, a novel anti-implantation indole alkaloid from murraya paniculata. 19854070445
coumarin-related compounds as plant growth inhibitors from two rutaceous plants in thailand.chemical investigation of naturally occurring plant growth inhibitors from rutaceous plants in thailand led us to identify five 7-methoxycoumarins and one 5,7-dimethoxycoumarin from murraya paniculata, and six furanocoumarins from citrus aurantifolia. of these compounds, murranganon senecioate (1) is a new natural compound found in m. paniculata. minumicrolin (6) was found to be highly active against the 2nd leaf sheath elongation of rice seedlings.200010737204
host plant affects morphometric variation of diaphorina citri (hemiptera: liviidae).the asian citrus psyllid (acp), diaphorina citri kuwayama, is one of the most serious citrus pests worldwide due to its role as vector of huanglongbing or citrus greening disease. while some optimal plant species for acp oviposition and development have been identified, little is known of the influence of host plants on acp size and shape. our goal was to determine how size and shape of acp wing and body size varies when development occurs on different host plants in a controlled rearing environ ...201627833820

the in vitro anti-giardial activity of extracts from plants that are used for self-medication by aids patients in southern thailand.this study evaluated the anti-giardial activity of chloroform, methanol and water extracts of 12 medicinal plants (39 extracts), commonly used as self medication by aids patients in southern thailand. the plant extracts and a standard drug, metronidazole, were incubated with 2x10(5) trophozoites of giardia intestinalis per millilitre of growth medium in 96-well tissue culture plates under anaerobic conditions for 24 h. the cultures were examined with an inverted microscope and the minimum inhibi ...200415614584
oxidative potential of some endophytic fungi using 1-indanone as a substrate.the oxidative potential of the fungus penicillium brasilianum, a strain isolated as an endophyte from a meliaceae plant (melia azedarach), was investigated using 1-indanone as a substrate to track the production of monooxygenases. the fungus produced the dihydrocoumarin from 1-indanone with the classical baeyer-villiger reaction regiochemistry, and (-)-(r)-3-hydroxy-1-indanone with 78% ee. minor compounds resulting from lipase and sam activities were also detected. the biotransformation procedur ...201222573162
essential oil variation from twenty two genotypes of citrus in brazil-chemometric approach and repellency against diaphorina citri kuwayama.the chemical composition of volatile oils from 22 genotypes of citrus and related genera was poorly differentiated, but chemometric techniques have clarified the relationships between the 22 genotypes, and allowed us to understand their resistance to d. citri. the most convincing similarities include the synthesis of (z)-β-ocimene and (e)-caryophyllene for all 11 genotypes of group a. genotypes of group b are not uniformly characterized by essential oil compounds. when stimulated with odor sourc ...201627338332
phylogenetic relationships of citrus and its relatives based on matk gene sequences.the genus citrus includes mandarin, orange, lemon, grapefruit and lime, which have high economic and nutritional value. the family rutaceae can be divided into 7 subfamilies, including aurantioideae. the genus citrus belongs to the subfamily aurantioideae. in this study, we sequenced the chloroplast matk genes of 135 accessions from 22 genera of aurantioideae and analyzed them phylogenetically. our study includes many accessions that have not been examined in other studies. the subfamily auranti ...201323638116
coumarins and flavonoid from murraya paniculata (l.) jack: antibacterial and anti-inflammation activity.the ethyl acetate extract of leaves of murraya paniculata (l.) jack was described in the previous in vitro study on the inhibition effect on the growth of periodontopathic bacteria and the reduction of cytokines from lps-stimulated macrophages. in this study, four coumarins including murrangatin (1), murrangatin acetate (2), murranganonesenecionate (3), micropubescin (4) and one flavonoid, 3', 4', 5', 7-tetramethoxyflavone (5) were isolated from the leaves of ethyl acetate extract of m. panicula ...201526639491
the evolution of cma bands in citrus and related genera.most species of citrus and related genera display a similar karyotype with 2n = 18 and a variable number of terminal heterochromatic blocks positively stained with chromomycin a(3) (cma(+) bands). some of these blocks are 45s rdna sites, whereas others may correspond to the main gc-rich satellite dna found in several citrus species. in the present work, the distribution of the 45s rdna and the main satellite dna isolated from c. sinensis (cssat) were investigated by in situ hybridization in seve ...201020490650
the anti-amoebic activity of some medicinal plants used by aids patients in southern thailand.the anti-amoebic activities of chloroform, methanol and water extracts from 12 thai medicinal plants (39 extracts) commonly used by aids patients in southern thailand were screened, at a concentration of 1,000 microg/ml, against entamoeba histolytica strain hth-56:mutm and strain hm1:imss growing in vitro. the extracts were incubated with 2x10(5) e. histolytica trophozoites/ml of medium at 37 degrees c under anaerobic conditions for 24 h. the cultures were examined with an inverted microscope an ...200616447069
isoflavonoids in the rutaceae family: 1. fortunella obovata, murraya paniculata and four citrus species.several types of compounds with immunoreactivity similar to isoflavonoids were detected in water: ethanol extracts of leaves of fortunella obovata hort. ex tanaka, murraya paniculata jack. and four citrus species, namely c. aurantium l, c. grandis osbeck, c. limonia osbeck., and c. sinensis osbeck (rutaceae). the chromatographic mobilities of the immunoreactive substances were compared with those of authentic standards, revealing a spectrum of isoflavonoid metabolites in all plants studied. agly ...200415508833
