As revised here, Discocarpus is interpreted to consist of three neotropical species: D. essequeboensis Klotzsch, D. gentryi S. M. Hayden, which is described and named herein as new to science, and D. spruceanus Mull. Arg. One previously accepted name, D. brasiliensis Klotzsch ex Mull. Arg., is reduced to synonymy of D. essequeboensis. Lectotypes are proposed for the two species previously descr...

Because low developmental stability may compromise the precision with which adaptations can be reached, the variability and genetic basis of developmental stability are important evolutionary parameters. Developmental stability is also an important clue to understanding how traits are regulated to achieve their phenotypic target value. However, developmental stability must be studied indirectly...

euphorbia macrostegia or persian wood spurge is one of the seventeen endemic plants of this genus in iran. three triterpenoids: 24-methylenecycloartan-3β-ol (1), butyrospermol (2) and cycloartenol (3) and three diglycerides: 1,2-di-o-α-linolenoyl-sn-glycerol (4), 1-o-linoleoyl-3-o-palmitoyl-sn-glycerol (5) and 1-o-α-linolenoyl-2-o-palmitoyl-sn-glycerol (6) were isolated from a hexane layer of m...

The in vitro antimicrobial activity of the crude methanolic and ethanolic leaf extract of Bridelia retusa (L.) Spreng. was studied against four gram negative and two gram positive bacteria. The results showed that both the extracts showed antimicrobial activity. Maximum zone of inhibition was observed in the methanolic extract against Escherichia coli which was 29.5 ± 0.50. However, ethanolic e...

piscicidal and molluscicidal activities of aqueous extracts of many members of the family euphorbiaceae are well-known, but the toxicity potential of euphorbia turcomanica was not yet studied on any aquatic animals. an acute toxicity test was performed by using a four-day static renewal test to determine the lc 50 value of dried powder of e. turcomanica for the euryhaline fish, aphanius dispar ...

(In vitro culture of Phyllanthus stipulatus (Euphorbiaceae)). An efficient micropropagation protocol was developed for the medicinal plant Phyllanthus stipulatus (Euphorbiaceae) using nodal segments for axillary shoot proliferation. Maximum multiplication rates (8-9 shoots per explant) was achieved on MS media supplemented with either 2.5-5.0 μM IBA. The best basal media for axillary shoot prol...

The stem bark of Croton gratissimus (Euphorbiaceae) yielded four cembranolides, including the first reported example of a 2,12-cyclocembranolide, (+)-[1R*,2S*,7S*,8S*,12R*]-7,8-epoxy-2,12-cyclocembra-3E,10Z-dien-20,10-olide, whose structure was confirmed by means of single crystal X-ray analysis. This compound showed moderate activity against the PEO1 and PEO1TaxR ovarian cancer cell lines.
