Kuntze (Lamiaceae) aerial parts were collected from four different localities in sub-Mediterranean area of Bosnia and Herzegovina and subjected to phytochemical profiling. Shade-dried and fresh samples were used to determine their headspace volatile organic composition by solid-phase microextraction on two differently coated fibers. Corresponding essential oils were obtained by hydrodistillation. Both headspace and essential oil were analysed by gas chromatography-mass spectrometry Among detected compounds, piperitenone oxide and pulegone were dominant in the headspace of shade-dried and fresh C. nepeta samples. The essential oils contained 42 compounds including pulegone (44.8%), piperitenone (48.8%) and piperitenone oxide (60.2%) as the major compounds, followed by limonene, cis piperitone oxide, p -menthone and dihydrocarvyl acetate. In this work, a wide range of volatile compounds present in C. nepeta samples from Bosnia and Herzegovina was determined. The obtained data provides detail phytochemical analysis of the volatiles of C. nepeta and therefore completes earlier researches of this plant from the other geographical areas.","PeriodicalId":21053,"journal":{"name":"Records of Natural Products","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49651524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gross structure of todasinoid A were established by analyses of the NMR and HRESIMS data. A comparison of the experimental ECD spectrum of 1 with the calculated ECD spectra for a model compound ( 1a ) resolved the absolute configuration of 1 . The known compounds were identified to be bullatantriol ( 2 ), aculeatin ( 3 ), 6-(3-ethoxy-2-hydroxy-3-methylbutyl)-5,7-dimethoxy-2H-1-benzopyran-2-one ( 4 ), trans -N-p-coumaroyltyramine ( 5 ), feruloyltyramine ( 6 ), − sitosterol ( 7 ), sitosterol D -glucoside( 8 ), 7 α -hydroxysitosterol ( 9 ) by comparing the NMR data and specific rotations with reported data in literature. Compound 1 is an eremophilane-type sesquiterpenoid containing a mercaptolactate side-chain that is rarely found in nature. Compounds 2 , 5 , and 9 were isolated from this plant for the first time. Bioassay study revealed that compound 5 exhibited inhibitory effects against  -glucosidase with an IC 50 of 320  M, being more active than the positive control acarbose.","PeriodicalId":21053,"journal":{"name":"Records of Natural Products","volume":"1 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69542896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structure of new compound 1 was determined by extensive spectroscopic analysis and electronic circular dichroism (ECD) calculation. Notably, this is the first reported monoterpene alkaloids from R. vomitoria . Besides, compounds 3 , 5 , and 7 – 9 were first discovered in the Apocynaceae family and compounds 4 and 6 were first reported in the Rauvolfia genus. This is also the first example of matrine-type alkaloids reported in the Apocynaceae family, indicating that matrine-type alkaloids are not unique to the Leguminosae/Fabaceae family. All isolated compounds were evaluated for their anti-acetylcholinesterase, anti-α-glucosidase, and antioxidant activities. Compound 6 showed significant α-glucosidase inhibitory activity and remarkable DPPH radical scavenging capacity, both of which are superior to the positive controls. Molecular docking of compound 6 with α-glucosidase was further performed, suggesting that compound 6 could form hydrogen bonds with residues ALA-292, ASN-259, and ARG-263.","PeriodicalId":21053,"journal":{"name":"Records of Natural Products","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43918064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
