Abstract
An unprescribed nortriterpenoid with an aromatic E ring, uncanortriterpenoid A (1), together with fourteen known triterpenoids (2-15), were isolated from the hook-bearing stems of Uncaria rhynchophylla Miq. Based on extensive spectroscopic analyses, the NMR data of 2, 5, and 10 in CD3OD were assigned for the first time, and the wrongly assigned δC of C-27 and C-29 of 2 were revised. Among the known compounds, 7, 13, and 15 were isolated from this species for the first time, and 15 represents the first lanostane triterpenoid bearing an extra methylidene at C-24 for the Rubiaceae family. Additionally, compounds 6 and 14 exhibited moderate ferroptosis inhibitory activity, with an EC50 value of 14.74 ± 0.20 μM for 6 and 23.11 ± 1.31 μM for 14.

Abstract
Two new quinoline alkaloids (1-2) together with twenty-two known alkaloids (3-24) were isolated and identified from Dictamnus dasycarpus Turcz. Compounds 6-7, 9, 11, 15-16, 19 and 24 were isolated from D. dasycarpus for the first time. The structures of all compounds were characterised by spectroscopic methods (1D, 2D NMR and HRESIMS). The anti-proliferative activity was mediated by the arrest of three human cancer cell lines (SW982, HepG2 and A549) of all the compounds that were evaluated by CCK-8 assay.

Abstract
OBJECTIVES Solanum lyratum Thunb (SLT) is a perennial plant of the Solanaceae family, and is extensively used in the clinical practice of traditional Chinese medicine. Malaria, oedema, gonorrhoea, cancer, wind and fever, jaundiced hepatitis, cholecystitis and rheumatoid arthritis are among the diseases that it is used to treat. To offer a foundation for further development and usage of SLT, the pieces of literature about the chemical composition and pharmacological action of SLT were reviewed and analysed. KEY FINDINGS The chemical constituents of SLT mainly included steroids, alkaloids, flavonoids, terpenoids, anthraquinones, phenylpropanoids and others. Pharmacological action mainly contains anti-tumour, antibacterial, anti-inflammatory, anti-oxidation and other pharmacological actions, among them, the anti-tumour effect is particularly outstanding. SUMMARY At present, studies on the pharmacological effects of SLT mainly focus on alkaloids and steroidal saponins. In the follow-up studies, studies on the pharmacological activities of other chemical components in SLT, such as flavonoids and terpenoids, should be strengthened. It has the potential to pave the way for more research and development of novel SLT medicines.
