The Cassia (Leguminosae) genus has attracted a lot of attention as a prolific source of
alkaloids and chromones with diverse structures and biological properties. The aim of this …

Two new alkaloids, 3-(hydroxymethyl)-6, 9-dimethyl-7H-benzo [de] quinolin-7-one (1) and 3-
(hydroxymethyl)-8-methoxy-6, 9-dimethyl-7H-benzo [de] quinolin-7-one (2), together with …

Two new chromones, 2-(2-(furan-2-yl)-2-oxoethyl)-6-methoxy-8-(2-oxopropyl)-chromone (1)
and 2-(2-(furan-2-yl)-2-oxoethyl)-5-methoxy-8-(2-oxopropyl)-chromone (2), along with four …

Two new phenolic compounds, 6-hydroxy-7-methoxy-3-(4-methoxyphenyl)-2 H-chromen-2-
one (1) and 7-hydroxy-6-methoxy-3-(4-methoxyphenyl)-2 H-chromen-2-one (2), together …

Two new compounds (1 and 2), together with three known chromone derivatives (3–5), were
isolated from Cassia leschenaultiana. Their structures were elucidated by spectroscopic …

Seven new chromones, siamchromones A–G (1–7), and 12 known chromones (8–19) were
isolated from the stems of Cassia siamea. Compounds 1–19 were evaluated for their …

Two new chromone derivatives, 5-(isobutyryl)-2-(2-oxopropyl)-7-methoxy-4 H-chromen-4-
one (1) and 5-(isobutyryl)-2-(2-oxopropyl)-6-methoxy-4 H-chromen-4-one (2), were isolated …

Two isoquinoline alkaloids, including a new natural product (1) and a compound (2) isolated
from plant for the first time, and named fistulatins A and B (1 and 2), together with four known …

Three new tricyclic alkaloid, siamalkaloids A–C (1–3), together with three known alkaloids (3–
6) were isolated from the twigs of Cassia siamea. Their structures were determined by …

Two structurally unique polyphenols, alatains A (1) and B (2), were isolated from the bark of
Cassia alata. Their structures were elucidated on the basis of spectroscopic analysis …
