Essential oil was extracted from the petroleum ether-soluble fraction of the leaves showed having antibacterial activity. It was demonstrated that the essential oil has significant antibacterial activity and the activity of the petroleum ether-soluble fraction is attributed to it. The constituents of the essential oil were analysized by GC-MS.10 relatively abundant components were identified on the basis of MS, among which Geranlgeraniol was found in the essential oil of Perilla frutescens leaves for the first time.

目的 探讨白花丹体外抗肿瘤作用的活性部位。方法 mtt染色法对白花丹五种溶剂提取物体外抗肿瘤活性进行了初步的研究。结果氯仿提取物对乳腺癌细胞（bre-04）、神经癌细胞（n-04）、肺癌细胞（lu-04）有较好的抑制生长作用，ic50分别为0.269 9 mg/ml、0.263 4 mg/ml、0.496 1 mg/ml，对肝癌细胞hepg2抑制作用差， ic50为0.937 9 mg/ml；白花丹石油醚提取部位对乳腺癌细胞（bre-04）、神经癌细胞（n-04）、肺癌细胞（lu-04）、肝癌细胞hepg2的ic50分别为0.590 2 mg/ml、0.572 5 mg/ml、0.793 8 mg/ml、0.637 4 mg/ml；乙酸乙酯提取物对肺癌细胞（lu-04）有一定的抑制作用，ic50为0.734 3 mg/ml；水溶性提取物以及正丁醇提取物无明显抑制肿瘤作用。结论白花丹氯仿提取部位、石油醚提取部位体外抗肿瘤作用较好，值得对其提取部位进一步分离纯化并研究其抗肿瘤作用机制。

The oil producer's astute risk management will make it the envy of Opec, the oil cartel whose members are struggling with a collapse in prices from last year's peak of $147 a barrel and who are due to meet tomorrow to discuss output levels.

石油生产国的充满智慧的风险管理措施使其成为OPEC中唯一幸免于难的国家。油价在去年达到147美元一桶后急速下滑，OPEC组织的其他成员国正面临巨大的困难，并将于明天会面讨论石油产量问题。

All one saw were the somnolent tanks filled with oil, hundreds of them, spread over the rolling hills, some brand-new, some more than 70 years old, and some holding, inside their silver or rust-orange skins, more than half a million barrels of oil each.

你所能见到的只有那堆放在绵延起伏的群山之中，数百桶装满石油令人昏昏欲睡的油罐，有些外壳崭新，有些则有着70多年的历史，在它们那银色或是锈成橘色的漆皮之下，有些油罐装过的石油不下50万桶。

Development and Reform Commission yesterday, the Ministry of Finance, the Ministry of Transportation and the State Administration of Taxation jointly issued a notice on the 5th, do not increase the current oil price on the premise of gasoline consumption tax allowance units from 0.2 yuan per liter To 1 yuan, 0.1 yuan per liter of diesel by up to 0.8 yuan, and other oil products unit increased allowances.

In this dissertation, the weak gels with good thermal stability and/or salt tolerance for use in EOR were prepared from HPAM and aluminium citrate or the compound containing hydroxymethyl groups in aqueous solution. The gelation mechanisms, structure, and properties of the HPAM-AlCA and HPAM-PRIM gels were investigated. For the HPAM-AlCA gelling system, the effects of aluminium : citrate and pH value on the properties of AlCA were systematically studied.

Mature, synrift lacustrine shales of Eocene to Oligocene age and mature, late rift coals and coaly shales of Oligocene to Miocene age are source rocks for oil and gas in two important petroleum systems of the onshore and offshore areas of the Northwest Java Basin. Biogenic gas and carbonate sourced gas have also been identified. These hydrocarbons are trapped primarily in anticlines and fault blocks involving sandstone and carbonate reservoirs.
