| [chemical components of the leaves of pistacia chinensis bge]. | six compounds have been isolated from the leaves of pistacia chinensis, a species of anacardiaceae family. their structures were identified on the basis of uv, ir, nmr, and ms as gallic acid, m-digallic acid, quercetin, 6-0-galloyl arbutin-quercitrin and quercetin-3-0(6''-galloyl)-beta-d-glucosides. | 1992 | 1445648 |
| in situ lipase-catalyzed reactive extraction of oilseeds with short-chained dialkyl carbonates for biodiesel production. | dimethyl/diethyl carbonate was adopted as extraction solvent and transesterification reagent at the same time for in situ lipase-catalyzed reactive extraction of oilseeds for biodiesel production in this work. fatty acid methyl esters and ethyl esters were respectively obtained with higher yields than those achieved by conventional two-step extraction/transesterification. the augment ranged from 15.7% to 31.7%. the key parameters such as solvent/seed ratio and water content were further investig ... | 2009 | 19615896 |
| structures of 4-aryl-coumarin (neoflavone) dimers isolated from pistacia chinensis bunge and their estrogen-like activity. | activity-guided fractionation of twigs of pistacia chinensis resulted in the isolation and characterization of two novel ingredients as potent estrogen agonists. on the basis of spectral analysis and comparison with a related compound their structures were elucidated as 3,3''-dimers of 4-aryldihydrocoumarins (3,4-dihydro-4-(4'-hydroxyphenyl)-7-hydroxycoumarin) differing only in the stereochemical disposition of the linkage between the two 4-arylcoumarin moieties. these compounds are the first ex ... | 2000 | 10783069 |
| Expression and characterization of recombinant Rhizopus oryzae lipase for enzymatic biodiesel production. | The Rhizopus oryzae lipase containing prosequence was expressed in Pichia pastoris. Recombinant lipase subunit showed a molecular mass of 32 kDa. The maximum activity of recombinant lipase obtained from Mut(s) recombinant was 90 IU/ml. The enzyme was stable in broad ranges of temperatures and pH, with the optimal temperature at 35 °C and pH 7.0. The crude recombinant R. oryzae lipase can be directly used for the transesterification of plant oils at high-water content of 60-100% (w/w) based on oi ... | 2011 | 21852124 |
| Does Landscape Fragmentation Influence Sex Ratio of Dioecious Plants? A Case Study of Pistacia chinensis in the Thousand-Island Lake Region of China. | The Thousand-Island Lake region in Zhejiang Province, China is a highly fragmented landscape with a clear point-in-time of fragmentation as a result of flooding to form the reservoir. Islands in the artificial lake were surveyed to examine how population sex ratio of a dioecious plant specie Pistacia chinensis B. was affected by landscape fragmentation. A natural population on the mainland near the lake was also surveyed for comparison. Population size, sex ratio and diameter at breast height (D ... | 2011 | 21829667 |
| [cold resistance of pistacia chinensis and koelreuteria integrifoliola]. | taking one-year-old dormant shoots of pistacia chinensis and koelreuteria integrifoliola as test materials and the shoots of northern indigenous tree species k. paniculata as the control, the changes of their membrane-lipid peroxidation, antioxidative enzyme activity, and organic osmoregulatory substance content under artificial cooling were studied, aimed to analyze the differences of the three tree species in cold resistance. with the decrease of temperature, the ion leakage percentage of the ... | 2011 | 21812286 |
| salt-driven interactions between pistacia lentiscus and salsola inermis. | it can be learned from the pistacia spp. germplasm collection (http://www.bgu.ac.il/pistacia) that the growth of salsola inermis is inhibited in the vicinity of the evergreen pistacia lentiscus, but not in the surroundings of the deciduous pistacia atlantica and pistacia chinensis. irrigation of trees during the summer months increases soil salinity around the trees. it was therefore hypothesized that inhibition of s. inermis around p. lentiscus is related to depletion of salt in the vicinity of ... | 2009 | 19727882 |
