甲黄

The occurrence of peridinin in the alga shows that Xanthophyta is closely related Dinophyta in terms of evolution.

多甲藻素在该种的存在显示了黄藻在进化上与甲藻有较近的亲源关系。

Dihydroxy-7, 4′-dimethoxy-dihydrflavonol and -3, 5, 7 -trihydroxy-4′-methoxy- dihydrflavonol were synthesized by selective protection, condensation, epoxidation, cyclization and deprotection from 2, 4, 6-trihydroxyacetophone and anisaldehyde.

以2，4，6-三羟基苯乙酮和茴香醛为起始原料，经选择性保护、缩合、环氧化、关环等步骤首次完成了-3，5-二羟基-7，4′-二甲氧基二氢黄酮醇和-3，5，7-三羟基-4′-甲氧基二氢黄酮醇全合成。

During the year-round survey, 46 species of dinoflagellates had been identified, within which 39 species were recognized as benthic dinoflagellate, including 15 common species and four dominant species.

2001年8月至2002年7月，对厦门岛东海岸黄厝沙滩底栖甲藻的种类组成和优势种的时空分布进行了为每月一次的调查，共鉴定甲藻种类46种，其中底栖种39种，常见种14种，优势种4种。

Chlorophyll a, c2 and c1 and the carotenoids fucoxanthin, diadinoxanthin, diatoxanthin and β,β-carotene were existed in all species. No new marker pigment was found in these species.

叶绿素中的叶绿素a、叶绿素c2、叶绿素c1和类胡萝卜素中的岩藻黄素、硅甲藻黄素、硅藻黄素和β，β-胡萝卜素存在于所有的种类中。

The above results suggests that the hydrolase and FMO in microsomes are involved in the formation of M1 and M2 respectively.

黄素单氧化酶的特异性抑制剂甲巯咪唑可以显著地抑制M2的形成，但对M1的形成无明显的抑制作用，且M1在肝微粒体中的形成为NADPH非依赖性，上述结果提示参与M1和M2代谢的酶分别为肝微粒体中的水解酶和黄素单氧化酶。

Commercially available 2 nitro 4 methoxyaniline was used as starting material and converted via reduction with zinc dust and cyclization with potassium ethyl xanthate into the title compound,suggesting that this procedure is suitable for industrial production.

以4 甲氧基 2 硝基苯胺为原料，经锌粉还原后，再与乙基黄原酸钾环缩合制得2 巯基 5 甲氧基 1H 苯并咪唑。结果收率80%。结论该方法简单易行，适合工业化生产。

The content of five free-anthraquinones (aloemodin, rhein, emodin, chrysophanol, physcion) in Alc95% active part were simultaneously determined by HPLC method.

其中7，3'-二羟基-5'-甲氧基异黄酮是自然界中罕见的B环为间位二取代的异黄酮类化合物，为新化合物。

RESULTS: A germacrane sesquiterpenoid, incaspitolide D (1), along with-N-benzoylphenylalanine--2-benzamido-3-phenyl- propyl ester (2), indole-3-carboxylic acid (3), apigenin (4), diosmetin (5) and luteolin (6) was isolated. CONCLUSION: Compounds 1-5 were isolated for the first time from Vernonia patula.

结果：分离到1个牻牛烷型倍半萜内酯， 1个苯丙氨酸衍生物、1个生物碱和3个黄酮化合物，根据波谱数据和X-衍射分析分别鉴定为：incaspitolide D (1)，-N-苯甲酰基苯基丙氨酸–-2-苯甲酰氨基–3-苯基丙酯(S-N-benzoylalanine-–2-benzamido-3-phenylpropyl ester， 2；吲哚-3-羧酸(indole-3-carboxylic acid， 3)；香叶木素(diosmetin， 4)，芹菜素(apigenin， 5)和木犀草素(luteolin， 6)。

In order to investigate effects of bound residues of metsulfuron-methyl on the activities of soil enzymes, the activities of urease, acid phosphatase, catalase, and sucrase were determined in Huangfentuspiked with bound residues of metsulfuron-methyl for 98 days.

为了研究甲磺隆结合残留对土壤酶活性的影响，将黄粉土经甲磺隆结合残留处理98天，检测土壤脲酶、酸性磷酸酶、过氧化氢酶和蔗糖酶活性。
