Tuberostemonine O from the roots of Stemona tuberosa
Stemonae Radix is the dried root of Stemona species (Stemonaceae) including S. tuberosa Lour, S. japonica (Blume) Miquel, and S. sessilifolia (Miquel) Miquel. Stemonae Radix is a traditional medicine
Morphological and chemical variation of Stemona tuberosa from southern China - Evidence for heterogeneity of this medicinal plant species.
TLDR
The obtained data show the need for future species delimitation to either species or subspecies level of Stemona tuberosa, as defined in the Flora of China, shows a remarkable variation in flower morphology and additionally in the accumulation of alkaloids.
Binary chromatographic fingerprint analysis of Stemonae Radix from three Stemona plants and its applications
TLDR
The results indicate that the chemical constituents from different parts of the underground material of Stemona plants are diverse and that the processing methods affect certain constituents in the root tuber samples, and show that the binary chromatographic fingerprint method can be used to differentiate the three officialStemona species or the adulterants of SR.
A review of the botany, traditional uses, phytochemistry and pharmacology of Stemonae Radix
TLDR
The up-to-date research progress in botany, traditional application, phytochemistry, pharmacology, toxicity, and quality control is summarized, and the research prospects and development direction of Stemonae Radix and its origin plants are discussed.

Stemona alkaloids represent a unique class of natural products exclusively known from the three genera Stemona, Stichoneuron, and Croomia of the monocotyledonous family Stemonaceae. Structurally they
Molecular analysis of Stemona plants in China based on sequences of four chloroplast DNA regions.
TLDR
A phylogenetic tree reconstructed by the trnH-psbA sequences for 9 Stemona species distributed in China and Thailand showed that the three CP species belonged to the same clade, among which S. japonica and S. sessillifolia formed a sister group, showing closer relations to each other than to S. tuberosa, while S. parviflora was genetically far from the threeCP species.

Antitussive activity of Stemona alkaloids from Stemona tuberosa.
TLDR
It is demonstrated, for the first time, that compounds 1 and 5 showed significant antitussive activities in guinea pig after cough induction by citric acid aerosol stimulation.
Alkaloids and chemical diversity of Stemona tuberosa.
Phytochemical investigation of the chemical components of Stemona tuberosa led to the isolation of two new alkaloids named tuberostemonine K (1) and tuberospironine (2), together with the known
Feeding deterrence and contact toxicity of Stemona alkaloids-a source of potent natural insecticides.
On the basis of chronic feeding bioassays with neonate larvae of Spodoptera littoralis reared on an artificial diet, the methanolic leaf and root extracts from Stemona collinsae displayed very high
Analyses of Stemona alkaloids in Stemona tuberosa by liquid chromatography/tandem mass spectrometry.
TLDR
The LC/MS fingerprints of these alkaloids could provide an overall characterization of the authenticity and quality of this species and help to differentiate it from S. japonica and S. sessilifolia, as all three species are recognized as genuine sources of the herb Radix Stemonae in the Pharmacopoeia of the People's Republic of China.
Antifungal stilbenoids from Stemona collinsae.
Fifteen new stilbenoids including 11 phenylbenzofurans, the stemofurans A-K (1-11), and four dihydrostilbenes, the stilbostemins A (15), C (17), E (19), and F (20), were isolated and identified from

TLDR
According to the volatile oil compositions, there are two chemotypes (Pogostone-type and Patchouliol-type) in Pogostemon cablin plant, which correspond to the genotypes of plastid matK gene and nuclear 18s rRNA gene by cluster analysis.
Analyses of the Volatile Compounds of Callitris columellaris F. Muell. Needles from Two Different Regions of Nigeria
Abstract Volatile compounds from the leaves of Callitris columellaris F. Muell. collected from Ibadan (southwest) and Kaduna (north central), Nigeria, were analyzed by GC and GC/MS. The predominant
Effects of airway inflammation on cough response in the guinea pig.
TLDR
The results suggest that airway inflammation potentiates an elevation of cough sensitivity in this model, and immunosensitized and multiple challenged animals showed an increased infiltration of inflammatory cells into the airway.
