    查看更多>>摘要：The genus Euphorbia is the largest in the Euphorbiaceae family with about 2000 species worldwide and is well known for the chemical diversity of their isoprenoid constituents [1].The plants of the genus Euphorbia consist of 80 species in China.Some of them have been used as traditional medicine to cure abdominal pain,abdominal distention,skin disease,and paralysis [2].Euphorbia is a rich source of diterpenoids with many different core frameworks such as jatrophanes,lathyranes,tiglianes,ingenanes,myrsinols,etc.In addition,sesquiterpenoids,phloracetophenones,cerebrosides,glycerols,flavonoids,and steroids were also obtained [3].Terpenes isolated from different Euphorbia species are known for many different activities,including antioxidant,antitumor,MDR reversing,antimicrobial,vasoactive,immunomodulatory,and anti-inflammatory effects [4].

    查看更多>>摘要：Knema plants {Myristicaceae family),which comprise over 80 tropical evergreen trees,are found in Southeast Asian countries with a characteristic red resin in the bark,referred to a word meaning"blood"in their local name.Knema saxatilis WJ.de Wilde,called"mau-cho,"is an endemic plant in Vietnam,growing in the mountain slopes or low hills of the central provinces [1 ].In folk medicine,Knema plant oils have been used for pimples and skin diseases [2].Knema plant extracts and their active components possess a wide range of biological activities such as anticancer,antibacterial,and acetylcholinesterase inhibitory activities [3-6].Previous studies focused on the chemical composition of the stem barks or trunk woods,which contain the red resin,with phenol lipid derivatives including anacardic acids,resorcinols,cardanols,and acetophenones found as major compounds [4-9],In addition,several lignans [10,11],stilbenes [12],and flavonoids [3,13] were also isolated from Knema species.In our continuing study on Vietnamese Knema plants [9],a total of 15 compounds including three sterols(1-3),a lignan(9),a sesquiterpene(7),a phenolic acid(4),and nine flavonoids(5,6,8,10-15)have been isolated from the leaves of K.saxatilis.On comparison of their physical and spectroscopic data with published values,they were identied as stigmast-4-ene-3,6-dione(1)sitoindoside I(2),5β-hydroxysitostanol(3),vanillic acid(4),kaempferol(5),3'-O-methylorobol(6),clovan-2β,9α-diol(7),luteolin(8)(+)-isolariciresinol(9),astragalin(10),(+)-catechin(11),isoquercitrin(12),dehydrocatechin A(13),proanthocyanidin A1(14),and biochanin A(15).This is the first report on the chemical constituents of Knema saxatilis.Among the isolated compounds,compounds 1-7,lignan 9,and flavonoid dimers 13,14 were reported for the first time from the genus Knema.

    查看更多>>摘要：Dialium is a genus of legume in the Caesalpinioideae family.The genus consists of about 30 species,of which most species occur in Africa [1] and some species are found in Asia [2].Previous phytochemical studies of plants of the genus Dialium revealed the presence of steroids,terpenoids,polyphenols and oleanolic acid glycosides [3,4].Dialium cochinchinense Pierre is a large and popular tree in Vietnam,distributed from the North to the South.Many parts of the plant have been used in folk medicine for treating various diseases,and the fruits of this species are also used as food as they help to improve appetite and digestion.Our screening program on plants of Dialium genus in Vietnam found that the ethyl acetate extract of D.cochinchinense stem bark showed potential cytotoxic effect against the KB cancer cell line(36.27% inhibition of KB cell line growth at the concentration of 1 μg/mL).To the best of our knowledge,this is the first phytochemical study on D.cochinchinense,which led to the isolation and characterization of 10 compounds(1-10).The structures of the isolated compounds were established,by means of spectroscopic methods and by comparison with previously reported data,as friedelin(1)[5],taraxerol(2)[6],isoswertisin(3)[7],epitaraxerol(4)[8],ursolic acid(5)[9],6-methoxycalopogonium isoflavone A(6)[10],velutin(7)[11],3',4'-O-dimethyltaxifolin(8)[12],7,3',4'-O-trimethyltaxifolin(9)[13],and durmillone(10)[14].
