Cephalotaxine ester of 2-oxo-6-methylheptanoic acid was treated with lithium diisopropylamide and Me O-(1-methoxyisopropyl)glycolate to give a mixture of homoisoharringtonine and its stereoisomers with 56% yield. The four stereoisomers separated by TLC showed identical mass spectra and almost superimposed IR but with different 1H NMR spectra. The configuration of the 2'-C and 3'-C of the four isomers were postulated based upon their 1H NMR spectra as compared with the 1H NMR spectra of isoharringtonine and its stereoisomers.

2-氧代-6-甲基庚酰基三尖杉碱(3)与0-(1-甲氧基异丙基)羟基乙酸甲酯(4)在强碱性试剂二异丙胺锂存在下，起亲核加成反应，反应中间体5在室温用酸性丙酮水解，得到一种新的三尖杉酯类生物碱一一高异三尖杉酯碱(6c)及其立体异构体(6a、6b、6d)的混合物，产率56%、通过制备薄层层析分得这四个立体异构体，它们的1H NMR和异三尖杉酯碱及其立体异构体的1H NMR类似，推定了它们的绝对构型。

The chemical constituents of Huperzia serrata Trev. are mainly flavonoids, triterpenoids and alkaloids. In order to get further comprehension of lycopodium alkaloids, we studied the low-polar section of the alkaloids extraction of Huperzia serrata and 19 alkaloids were isolated by ways of silica gel, RP-18 and Sephadex LH-20 etc. All of their structures, including five new compounds and two known ones that were firstly found from this genus, were elucidated with the help of Mass, IR, NMR spectra and so on. The five new alkaloids (HS-07, HS-08, HS-09, HS-10 and HS-11) are belonged to lycopodine class. The other two ones that were new to this genus (HS-18 and HS-19) are belonged to miscellaneous group.

蛇足石杉的主要化学成分为黄酮，三萜和生物碱，为进一步了解该植物的生物碱成分，我们研究了蛇足石杉氯仿总碱低极性部位的生物碱成分，运用正相硅胶、反相RP-18、凝胶LH-20等方法分得了19个生物碱，并通过质谱、红外、核磁共振等波谱鉴定了它们的结构，其中5个为新化合物，2个为首次从该属植物中分离得到的化合物，所分得的新化合物：HS-07、HS-08、HS-09、HS-10和HS-11均为lycopodine类石松生物碱，首次从该属植物中分得的化合物为miscellaneous类：HS-18和HS-19。

If this is a republican group, dress well, clean and conservative, if it's a democrat group, use more casual clothe, if it's a Nadder socialist group, open a hole in your rainbow color T-shirt, and show your rolling paper around.

如果是共和党小组，礼服干净保守，如果它是民主党小组，用更加偶然的穿着，如果是会主义团体，打开你的彩虹颜色T恤杉的一个袖子，并且秀出你的卷轴式记录纸。

To investigate the mechanism of wood formation and lignin biosynthesis, it is important to understand the function and characteristic of OMT. In the present study, a set of primer was designed based on the conserved region of OMT genes from several woody and non-woody plants, to clone the counter part gene by PCR and RACE from Chamaecvparis formosensis Matsum., Chamaeeyparis obtusa var. Jormosana, Abies kawakarnii, Tsuga ehinensis var. Jormosana and Taiwania eryptonierioide Hayata. The cloned genes were sequenced and their amino acid sequences predicted.

我们自资料库中收集并分析已发表之草本和木本植物caffeoyl CoA3-O-methyltransferase序列，在具高保守性的序列中设计了一对引子，并对红桧、台湾扁柏、台湾冷杉、台湾铁杉和台湾杉进行OMT基因的钓取，同时配合RACE的策略，成功获得红桧、台湾扁柏、台湾杉的全长基因及台湾冷杉与台湾铁杉之部分基因片段。

The content of assemble alkaloids of huperzine in 10 different geographical populations of Huperzia serrata and Phlegmariurus cryptomerianus from Zhejiang and Fujian Province was determined,and their phenetic differentiation in chemical composition was studied using the method of dedentred correspondence analysis based on their UV spectra.
