Publisher Summary This chapter discusses taxonomy, indole alkaloids from chemically
investigated Tabernaemontana species, structure elucidation and chemistry, and …

During chemical investigation for compounds possessing biological activity in the root bark
of Tabernaemontana catharinensis, six alkaloids were isolated: 12-methoxy-4 …

The isolation of 18 indole alkaloids from a whole plant extract of Tabernaemontana elegans
is described. Five new and 13 known alkaloids were isolated and identified. The five new …

Re-investigation of leaves and twigs of T. glandulosa (collected from Ghana) yielded 11
indole alkaloids, and known phenylpropanoids and pentacyclic triterpenes. The structures of …

Nine alkaloids, 8 of which were isolated for the first time from this plant, were isolated from
the stems and leaves of T. pandacaqui (collected from the Philippines). The main alkaloid …

The taxonomy, phytochemistry, ethnobotany, and pharmacology of the genus
Tabernaemontana L.(Apocynaceae) is reviewed. The genus is currently being revised …

Continued interest in cytotoxic alkaloids resulted in the isolation of 37 alkaloids including 29
known monoterpenoid indole alkaloids from the aerial parts of Tabernaemontana officinalis …

The alkaloids of two Amazonian species of Tabernaemontana havebeen studied; each
species yielded indole alkaloids of only one structural type. Thus, T. riedelii contained the …

A re-investigation of the root bark of Tabernaemontana divaricata resulted in the isolation of
18 compounds, viz. α-amyrin acetate, lupeol acetate, α-amyrin, lupeol, cycloartenol, β …

EXPERIMENTAL The residue obtained after concentrating the EtOH extract of the fresh
leaves (60 kg; single petal variety) was macerated with tartaric acid soln (4%, 8 x 1 I.). The …
