  chinese tallow leaves
Effects of tannins on the decomposition of Chinese tallow leaves by terrestrial and aquatic invertebrates
      
The hypothesis of this study was that tannins from Chinese tallow leaves have a negative effect upon terrestrial and aquatic reducer organisms and thereby may affect the overall rate of tallow litter decomposition.

The change of protein composition and esterase isozymes in Oncomelania hupensis under agro forestry systems and covering with Chinese tallow tree leaves were studied in this paper.The result showed that the O.hupensis under agro forestry systems had a change in their protein composition,with a new protein (about 56 KD) belt on SDS PAGE,while the O.hupensis under covering with Chinese Tallow Tree leaves showed no such change.However,these two kinds of O.hupensis produced an identical new esterase isozyme.It...

研究在覆盖乌桕叶和林下间种等胁迫条件下, 钉螺体内蛋白质组分和酯酶同工酶的变化。结果表明, 林下间种区的钉螺体内可溶性蛋白质在SDS—PAGE上出现一条新的组分, 其分子量约为56KD, 而覆盖乌桕叶的钉螺体内蛋白质则无明显的变化。两种胁迫条件下钉螺酯酶同工酶比对照材料都多出一条有同样迁移率的酯酶同工酶。据此推测林下间种的胁迫作用要大于覆盖乌桕叶

Leaf protein contents of 10 Chinese tallow varieties (Sapium sebiferum) ranged from 58 to 104 g·kg~(-1) dry matter. Intervarietal differences in relative amino acid contents of Chinese tallow leaves were not very evident, but differences of ammonia and non-protein nitrogen in levels were notable. The nitrogen-to-protein conversion factors (Kp) for 10 varieties based on Kjeldahl nitrogen ranged from 3.73 to 5.97, showing that the traditional conversion factor of 6.25 was not valid for Chinese tallow leaf proteins....

The functional composition of bacteriostatic activity from Chinese tallow leaves was investigated. The bacteriostasis of the extraction of different varieties Chinese tallow leaves were tested with Escherichia coli and Staphylococcus aureus. Their total acids and flavonoids content were determined. The relativity between bacteriostasis and the chemical composition were studied. The results show taht bacteriostasis of total acid is prior in aqueous solution extract to other solvent. Their activities are 72% extract...

The functional composition of bacteriostatic activity from Chinese tallow leaves was investigated. The bacteriostasis of the extraction of different varieties Chinese tallow leaves were tested with Escherichia coli and Staphylococcus aureus. Their total acids and flavonoids content were determined. The relativity between bacteriostasis and the chemical composition were studied. The results show taht bacteriostasis of total acid is prior in aqueous solution extract to other solvent. Their activities are 72% extract with aqueous, 63.2% with 70% ethanol and 3.5% with ethyl acetate. Flavonol glycosides has stronger activity than that in the form of flavonol. Our results show that it was acids and flavonoids of Chinese tallow leaves that carry bacterostatic functions.

分析了乌桕叶中的抑菌活性功能成分。以大肠杆菌和金黄色葡萄球菌为受试菌,依次测定不同种质乌桕叶水、70 %乙醇和乙酸乙酯3种溶剂提取物的抑菌活性和其所含总酸和总黄酮物质的含量,分析它们的相关性。用碱中和法和分离的黄酮类物质的实测法确定了抑菌活性物质。结果显示,总酸在乌桕叶极性溶剂提取物抑菌中起主要作用。总酸在水、70 %乙醇、乙酸乙酯3种溶剂提取物中抑菌分别占其抑菌活性的72 %、6 3 2 %和3 5 %。黄酮苷比苷元抑菌活性强。酸类物质和黄酮类物质是乌桕叶抑菌活性的功能成分。
