abstract

amaryllidaceae is a well-known family for its high alkaloidal content. these alkaloids comprise a unique group of bases that have been found to occur in this family. the amaryllidaceae alkaloids represent a large and still expanding group of isoquinoline alkaloids, the majority of which are not known to occur in any other family of plants this article reports on the phytochemical investigation of the alkaloidal content of the flowers of clivia nobilis cultivated in egypt which resulted in the isolation of four alkaloids; lycorine with pyrrolo{de}phenanthridine nucleus (lycorine-type) which is the common alkaloid of the amaryllidaceae family, clivatine nobilisine, both with [2]benzopyrano (3,4-g) indole nucleus (lycorenine-type) and (+) 8-o-demethylmaritidine with 5,10b-ethanophenanthridine nucleus (crinine-type). furthermore, the antimicrobial activity of the chloroform extract of the flowers of c. nobilis along with some of the isolated alkaloids has been studied.

Phytochemical and Biological Studies on the Different Organs of Tanacetum parthenium L. Cultivated in Egypt

Phytochemical investigation of Tanacetum parthenium L. family Asteraceae cultivated in Egypt resulted in isolation and identification of four flavonoids. One surface flavonoid was isolated from the fresh leaves and three other flavonoids were isolated from the flower heads. Four sesquiterpene lactones were isolated from the leaves. Two sterols were isolated from the roots. A comparative study o...

Further Pharmacognostical and Biological Studies on the Flowers of Oenothera Speciosa Nutt. Cultivated in Egypt

The effect of the time of collection on the phenolic content of the flowers of Oenothera speciosa Nutt., cultivated in Egypt, was studied. Samples collected at the early (March) and late (July) flowering periods were analyzed. Flavonoids (expressed as aglycones) and phenol acids were determined by HPLC in the hydrolyzed extracts. Samples gathered in March showed a relatively high percentage of ...

Isolation and Identification of Fourteen Microsatellite Markers in Clivia miniata and Clivia nobilis (Amaryllidaceae)

Clivia is a genus of great horticultural importance and has been widely cultivated as ornamental plants in all over the world. In order to assess the phylogenetic relationships and genetic diversity of the wild Clivia species and cultivars, we isolated AC-enriched repeats using FIASCO from a single clone each of C. miniata Regel. and Clivia nobilis Lindl. Of the fourteen repeats, 10 were polymo...
