Two new steroidal alkaloids (1-2) have been isolated from the leaves and roots of Solanum hypomalacophyllum Bitter, respectively. Their structures have been elucidated as deacetoxysolaphyllidine-3-O-β-D-glucopyranoside (1) and 4-keto-5,6dihydro-(20S)-verazine (2). Furthermore, two known steroidal alkaloids, 20R-verazine and 20S-verazine, and the common secondary metabolites oleanolic acid and β-sitosterol were isolated from the roots, whereas deacetoxysolaphyllidine was obtained from the leaves.
The essential oil from the leaves of Phyllanthus acidus (Phyllanthaceae) was obtained by hydrodistillation and its composition determined by GC and GC/MS. Twenty-one compounds were identified, representing 92.8 % of the oil. The most abundant components were t-muurolol (20.4 %), α-cadinol (14.6 %), β-cadinene (8.9 %) and α-muurolene (7.5 %).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
