Paeonia ostii is now being extensively planted for oil extraction in China, which is recognized as a single oil‐use tree peony cultivar and commonly called ‘Fengdan’. This study investigated the effects of nitrogen fertilizer on oil yield, fatty acid compositions and antioxidant activity of P . ostii . Oil yield (33.46%), oleic acid (25.12%), linoleic acid (29.21%) and a‐linolenic acid (43.12%) reached

This study aimed to investigate the metabolic effects of endophytic fungi in Gentiana rigescens . From the 100 selected morphospecies , strain 7‐2 ( Penicillium brasilianum ) showed a remarkable biocatalytic activity for gentiopicroside and swertiamarin, yielding seven products, including one new compound, 5‐ethylidene‐8‐hydroxy‐4,5,6,8‐tetrahydropyrano[3,4‐ c ]‐pyran‐1‐one ( M04 ), alongside six known

Medicinal mushrooms have tremendous potential in production of bioactive compounds with diverse bioactivities while the biochemical potential of some specific mushroom strains (autochthonous for the region) in production of specific bioactive agents may be of the main importance in a continuous search for novel strains with supreme activities world over. In this study, the ethanolic (EtOH) and water

The continued development of folk medicine to potentially treat infectious diseases has resulted in an increase in natural sources of antimicrobial agents, particularly the use of plant essential oils containing volatile products from secondary metabolism. The objectives of this investigation were to (i) analyze the chemical components of essential oils using GC‐MS, and (ii) to examine their in vitro

Two new yohimbine‐type monoterpene indole alkaloids rauvine A and B ( 1 − 2 ) and six known derivatives ( 3 − 8 ) were obtained from the leaves of R. vomitoria . The structures of the two new alkaloids were determined by extensive spectroscopic analyses, 13 C NMR and ECD calculations. This is the first time to determine the absolute configurations of yohimbine‐type N ‐oxides by quantum chemistry calculations

Thirty Boraginaceae species from different tribes were evaluated in a search of γ‐linolenic (GLA, 18:3 n‐ 6)‐ and stearidonic acid (SDA, 18:4 n‐ 3)‐rich oils. The higher GLA percentages were found in the seed oils of Symphytum bulbosum and S. tuberosum subsp. tuberosum (27.6 and 27.2% of total fatty acids (FA)), which are unusual values for GLA‐oils in the current literature. On the whole seed, noticeable

Three new β ‐triketone flavanone hybrids, cajuputones A–C ( 1 – 3 ) were obtained from Melaleuca cajuputi (the Australian “tea tree”) . The structures of compounds 1 – 3 were elucidated by 1D/2D NMR spectroscopy and HRESIMS analyses, and absolute configurations of them were established by electric circular dichroism (ECD) calculations using TDDFT method. Structurally, compounds 1 – 3 feature a rare

Lodoicea maldivica (J. F. Gmel.) Pers. (Arecaceae), ‘Coco de Mer’, is a palm, growing as endemic in the Seychelles islands. Its fruit weighs up to 20 kg and is characterized by a fleshy and fibrous envelope surrounding the nutlike portion. The present work combines for the first time a morpho‐anatomical and a phytochemical analysis of the fruit exocarp and mesocarp. The exocarp is composed by a layer

Colorectal cancer (CRC) is one of the most common malignant tumors in the world. In this study, the Caco‐2 in vitro cell model was used to study the effect and mechanism of Aronia melanocarpa Elliot anthocyanins (AMA) on colon cancer. The experimental results showed that the binding energy of anthocyanins on β‐Catenin was in the range of ‐5.92 to 4.95 kcal/mol, with good low energy parameters and binding

Cisplatin (CISP) is an efficacious anticancer agent used in chemotherapy, however, the constraint to its clinical utility is the stray organ toxicity including testicular damage linked to oxidative and inflammatory cascades. This study aimed to explore the protective effect of nucleosides‐rich extract from Cordyceps cicadae (NRCE) against CISP‐induced testicular damage in rats. Rats were subjected

Two new oligostilbenes, caragasinins D (1) and E (2), along with four known compounds, kobophenol A (3), α‐viniferin (4), wistin (5), and 5‐hydroxy‐2‐[2‐(4‐hydroxyphenyl)acetyl]‐3‐methoxylbenzoic acid (6) were isolated from Caragana sinica roots. These compounds were spectroscopically analyzed for their structure and stereochemistry and compared with existing data. The configurations of 1 and 2 were

Thirteen commercial essential oils were assessed for their possible inclusion in a mouthwash formulation based on their inhibitory effect against potentially pathogenic anaerobic oral bacterial isolates from subgingival plaque, and their cytotoxicity towards gingival cells. The essential oils, originating from species belonging to seven major aromatic plant families, were chosen to provide the necessary

This study presented a micromorphological and phytochemical survey on Lavandula dentata L. cultivated at the Ghirardi Botanic Garden (Toscolano Maderno, BS, Italy). The morphological investigation revealed the presence of peltate, short‐ and medium‐stalked capitate trichomes. The histochemical survey showed terpenes production by peltates and medium‐stalked capitates, hydrophilic secretions by short‐stalked

The phytochemical investigation of the leaves and stems of Murraya tetramera C. C. Huang, a traditional folk medicine used as an anti‐inflammatory agent, yielded 19 simple carbazole alkaloids, two of which (1‐ethoxy‐2‐hydroxy‐3‐methylcarbazole and 1,7‐dimethoxy‐8‐formyl‐2‐hydroxy‐3‐methylcarbazole, 1 & 2) are new ones. The structures of the new compounds were determined by extensive spectroscopic analysis

Conotrachelus dimidiatus (Coleoptera: Curculionidae) interacts with immature guava fruits ( Psidium guajava L.) for feed, sleep, mate and oviposit. Determination of the volatile organic compounds (VOCs) emitted by the insect and immature fruits can help improve understanding of plant‐insect and intraspecific insect interactions between females and males of C. dimidiatus . Daytime fruit setting emissions

The EtOAc extract of Artemisia argyi‐derived Fungus Trichoderma koningiopsis QA‐3 showed potent inhibitory activity against pathogenic bacteria. Fractionation of the extract resulted in the isolation of three new polyketides (1–3) and two new terpenoids (4 and 5), together with three known metabolites (6–8). Their chemical structures were analytically analyzed by NMR spectra, ECD, HRESIMS or HREIMS

In this study, bufalin was glycosylated by an efficient chemo‐enzymatic strategy. Firstly, 2‐chloro‐4‐nitrophenyl‐1‐ O‐ b ‐D ‐glucoside (sugar donors) was obtained by chemical synthesis. Then the glycosylation of the bufalin was achieved with the synthesized sugar donor under the catalysis of two glycosyltransferase s (Loki and ASP). Finally, two glycosides, i.e. bufalin‐3‐O‐b‐D‐glucopyranoside ( 3

Toona sinensis (A. Juss.) Roem, a multi‐purpose tree, is widely distributed and intensively cultivated in Asia, yet its high yielding, lipid‐rich seeds are rarely exploited. The present study systematically analyzed the differences and correlations of seed morphological characteristics and fatty acid (FA) profiles of 62 representative T. sinensis germplasms distributed across northern to southern China

Myrtucyclitones A–C ((+)‐and (−) ‐1 – 3 ), three pairs of new triketone‐phloroglucinol‐triketone hybrids were isolated from the plant Myrtus communis .
