Abstract
These days, easy access to commercially available (poly)phenolic compounds has expanded the scope of potential research beyond the field of chemistry, particularly in the area of their bioactivity. However, the quality of these compounds is often overlooked or not even considered. This issue is illustrated in this study through the example of (dihydro)phenanthrenes, a group of natural products present in yams, as AMP-activated protein kinase (AMPK) activators. A study conducted in our group on a series of compounds, fully characterized using a combination of chemical synthesis, NMR and MS techniques, provided evidence that the conclusions of a previous study were erroneous, likely due to the use of a misidentified commercial compound by its supplier. Furthermore, we demonstrated that additional representatives of the (dihydro)phenanthrene phytochemical classes were able to directly activate AMPK, avoiding the risk of misinterpretation of results based on analysis of a single compound alone.

Discovery of Anti-NRLP3 Inflammasome, Immunomodulatory Phytochemicals from the Extract of Habenaria intermediaD. Don: An Unexplored Plant Species. ACS OMEGA 2023; 8:31112-31122. [PMID: 37663462 PMCID: PMC10468832 DOI: 10.1021/acsomega.3c03071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Accepted: 07/20/2023] [Indexed: 09/05/2023]
Abstract
The present study describes the isolation, identification, and quantification of biomarker compounds in plant extracts of Habenaria intermedia D. Don (Orchidaceae). The isolation of the compounds was carried out from H. intermedia D. Don by repeated column chromatography of petroleum ether and ethanol fractions of extract of tubers. These compounds were characterized by 1H and 13C NMR and mass spectral data. A new quantitative method was established by using high-performance liquid chromatography (HPLC)-PDA. As a result, seven compounds were isolated and characterized. This is the first report of isolation of these compounds from this plant species H. intermedia D.Don. Out of seven isolated compounds, five were used for the quantitative study. A reliable and suitable HPLC method was developed for the well-resolved chromatogram of compounds. The proposed method was applied successfully to the detection and quantification of compounds. This study also represents the immunomodulatory and anti-inflammasome biological studies of isolated natural products. Loroglossol (HBR-4) has been reported to possess immunomodulatory activity. The immunostimulating assay indicated that HBR-4 could significantly promote the cell proliferation, especially via IL-2, TNF-α, and IFN-γ secretion from spleen cells. These results suggested the potential utilization of HBR-4 as an attractive functional health supplement candidate for hypoimmunity population. Additionally, cyclophosphamide-induced immunosuppression was counteracted by treatment with HBR-4, revealing significant increase in hemagglutinating antibody responses and hemolytic antibody responses. The current work revealed the potential anti-inflammasome and immunomodulatory activities of H. intermedia D. Don compounds and validates the usage of this prominent Rasayna plant.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gymnadenia conopsea, a perennial herbaceous flowering plant that belongs to the family of Orchidaceae, sporadic distributed in the altitudes of 200-4700 m across northern Europe and, temperate and subtropical Asia region. The dried tubers of G. conopsea have been used to treat cough, asthma, and their syndromes, and also as a tonic in China and surrounding countries for a long history. G. conopsea is often processed deeply processed before use to enhance its efficacy. In recent years, because of its remarkable pharmacological activity and health care function, G. conopsea has been used more and more widely. Due to its extensive application and bad growth environment, the wild distribution of G. conopsea is decreasing and it has been listed as an endangered plant. AIM OF THE REVIEW This review aims to summarize the propagation and breeding, traditional uses, chemical composition, pharmacology, quality control, and processing of G. conopsea. Moreover, it also provides suggestions for the future high-value utilization of G. conopsea. MATERIALS AND METHODS A literature search on Gymnadenia genus and G. conopsea was performed using scientific databases including SciFinder, ACS, Web of Science, Springer, ScienceDirect, PubMed, and CNKI. Information was also collected from classic books of Chinese herbal medicine, official websites, Ph.D. and M.Sc. Dissertations, and so on. Structures of chemical compounds were drawn by ChemDraw software. RESULTS As of submission date of this manuscript, total 170 natural compounds have been isolated and characterized from G. conopsea, and all of the compounds were isolated from the tubers. The isolated compounds including benzylester glucosides, dihydrostilbenes, phenanthrenes, phenolic compounds, alkaloids, polysaccharide, lignans, flavones, triterpenoids, steroids, and other compounds. Some of these compounds and active extracts exhibited a wide range of pharmacological activities, in which, the tonifying, anti-fatigue, anti-oxidant, anti-viral, sedative and hypnotic activities are consistent with the traditional uses for the treatment of diseases. In addition, a variety of new pharmacological activities, such as preventing and treating gastric ulcers, immunoregulatory, anti-hyperlipidemia, anti-anaphylaxis, anti-silicosis, anti-cancer and neuroprotective activities have also been reported. However, the bioactive compounds responsible for most of the above pharmacological effects have not been well summarised till now. In this manuscript, analysis, speculation and summary of compounds that responsible for pharmacological effects were conducted. CONCLUSIONS The chemical constituents and pharmacological activities studies of G. conopsea extract have been summarised in this context, the isolated compounds responsible for the pharmacological activities were also analyzed and deduced according to the publications, all above led to suggestions for the future high-value utilization of G. conopsea.

Abstract
Six previously undescribed components, bis(4-glycosyloxybenzyl) 2-isobutyltartrate derivatives (pholidotoside A-E) and phenolic glycoside (pholidotosin A), together with twenty known compounds were isolated from the pseudobulbs of Pholidota chinensis. Their structures and absolute configuration were elucidated and established through various spectroscopic and chemical methods. The anti-inflammatory potential of selected compounds was examined using a human neutrophil cell model activated by N-formyl-methionyl-leucyl-phenylalanine/cytochalasin B (fMLP/CB). Among these, dihydrophenanthrenes exhibited potent inhibitory effect on both superoxide anion generation and elastase release assays with IC50 values ranging from 0.41 ± 0.05 to 7.14 ± 0.30 μM.

Abstract
The first total syntheses of the orchid-derived natural products isoarundinin I (1), (±)-bleochrin F ((±)-2), (±)-blestanol K ((±)-3), and (±)-pleionol ((±)-4) from renewable starting materials are reported, along with the evaluation of their biological activities. The total syntheses were based on regioselective aromatic bromination reactions in combination with a key acid-promoted regioselective intramolecular cyclization. The biological results suggest that isoarundinin I (1), (±)-blestanol K ((±)-3), and (±)-pleionol ((±)-4) have the potential to inhibit the growth of both sensitive and multidrug-resistant cancer cells.

Abstract
Objective To study the protective activities of the dietary malate esters derivatives of Bletilla striata against SiO2 nanoparticles-induced A549 cell lines and its mechanism action. Methods The components were isolated and elucidated by spectroscopic methods such as 1D NMR and 2D NMR. And MTT assays was used to tested these components on the A549 cell survival rates and ROS or proteins levels were detected by Western blotting. Results A new glucosyloxybenzyl 2-isobutylmalate (a malate ester derivative), along with 31 known compounds were isolated and identified from n-BuOH extract of EtOH extract of B. striata. Among them, compounds 3, 4, 11, 12 and 13 possessed noteworthy proliferative effects for damaged cells, with ED50 of 14.0, 13.1, 3.7, 11.6 and 11.5 µmol/L, respectively, compared to positive control resveratrol (ED50, 14.7 µmol/L). Militarine (8) prominently inhibited the intracellular ROS level, and increased the expression of Nrf2 and its downstream genes (HO-1 and γ-GCSc). Furthermore, Nrf2 activation mediates the interventional effects of compound 8 against SiO2 nanoparticles (nm SiO2)-induced lung injury. Moreover, treatment with compound 8 significantly reduced lung inflammation and oxidative stress in nm SiO2-instilled mice. Molecular docking experiment suggested that 8 bound stably to the HO-1 protein by hydrogen bond interactions. Conclusion The dietary malate esters derivatives of B. striata could significantly increase the viability of nm SiO2-induced A549 cells and decrease the finer particles-induced cell damages. Militarine is especially promising compound for chemoprevention of lung cancer induced by nm SiO2 through activation of Nrf2 pathway.

Abstract
Background As Gymnadenia R.Br. (Gym) has an obvious uric acid-lowering effect, but its specific bioactive substances and mechanism are still unclear. The key metabolites and pathways used by Gym to reduce uric acid (UA) were identify. Methods An optimized extraction process for urate-lowering active substances from Gym was firstly been carried out based on the xanthine oxidase (XOD) inhibition model in vitro; then, the Ultra-high-performance liquid chromatography and Q-Exactive mass spectrometry (UHPLC-QE-MS) based on non-targeted metabolomics analysis of Traditional Chinese Medicine were performed for comparison of Gym with ethanol concentration of 95% (low extraction rate but high XOD inhibition rate) and 75% (high extraction rate but low XOD inhibition rate), respectively; finally, the protective effect of ethanolic extract of Gym on zebrafish with Hyperuricemia (referred to as HUA zebrafish) was explored. Results We found that the inhibition rate of Gym extract with 95% ethanol concentration on XOD was 84.02%, and the extraction rate was 4.32%. Interestingly, when the other conditions were the same, the XOD inhibition rate of the Gym extract with 75% ethanol concentration was 76.84%, and the extraction rate was 14.68%. A total of 539 metabolites were identified, among them, 162 different metabolites were screened, of which 123 were up-regulated and 39 were down-regulated. Besides significantly reducing the contents of UA, BUN, CRE, ROS, MDA, and XOD activity in HUA zebrafish by Gym and acutely reduce the activity of SOD. Conclusion Along with the flavonoids, polyphenols, alkaloids, terpenoids, and phenylpropanoids, the ethanolic extract of Gym may be related to reduce the UA level of Gym.

Abstract
Gymnadenia conopsea R. Br. is a traditional Tibetan medicinal plant that grows at altitudes above 3000 m, which is used to treat neurasthenia, asthma, coughs, and chronic hepatitis. However, a comprehensive configuration of the chemical profile of this plant has not been reported because of the complexity of its chemical constituents. In this study, a rapid and precise method based on ultra-high performance liquid chromatography (UPLC) combined with an Orbitrap mass spectrometer (UPLC–Orbitrap–MS/MS) was established in both positive- and negative-ion modes to rapidly identify various chemical components in the tubers of G. conopsea for the first time. Finally, a total of 91 compounds, including 17 succinic acid ester glycosides, 9 stilbenes, 6 phenanthrenes, 19 alkaloids, 11 terpenoids and steroids, 20 phenolic acid derivatives, and 9 others, were identified in the tubers of G. conopsea based on the accurate mass within 3 ppm error. Furthermore, many alkaloids, phenolic acid derivates, and terpenes were reported from G. conopsea for the first time. This rapid method provides an important scientific basis for further study on the cultivation, clinical application, and functional food of G. conopsea.

Abstract
Oomycetes are one type of the most highly destructive of the diseases that cause damage to some important crop plants, such as potato late blight, cucumber downy mildew, and grape downy mildew. As main approach of the ongoing search for new botanical fungicide from plant, the secondary metabolites of D. aspersa were investigated. Through efficient bioassay-guided isolation, two new (1 and 2) and 12 known compounds (3 - 14) were isolated, and their structures were determined via extensive NMR, HR-ESI-MS, and IR. They were isolated from this genus for the first time except for compounds 11 and 12. The biological properties of 1 - 14 were evaluated against Pseudoperonospora cubensis and Phytophthora infestans. Compounds 1 - 8 showed potent antifungal activity in vitro. Additionally, compound 3 has preferable control effect on cucumber downy mildew, showing dual effect of protection and treatment in vivo.

Abstract
Gymnadenia conopsea (L.) R. Br. (Orchidaceae) is a perennial herbaceous orchid plant that grows widely throughout Europe and in temperate and subtropical zones of Asia. In China, its tuber has been used in traditional Chinese medicines, Tibetan medicines, Mongolian medicines and other ethnic medicines, and taken to treat numerous health conditions. The present paper provides a review of the traditional uses, phytochemistry, biological activities, and toxicology to highlight the future prospects of the plant. More than 120 chemical compounds have been isolated, and the primary components are glucosides, dihydrostilbenes, phenanthrenes, aromatic compounds, and other compounds. G. conopsea and its active constituents possess broad pharmacological properties, such as the tonifying effect, anti-oxidative activity, anti-viral activity, immunoregulatory, antianaphylaxis, antigastric ulcer, sedative, and hypnotic activities, etc. However, overexploitation combined with the habitat destruction has resulted in the rapid decrease of the resources of this plant, and the sustainable use of G. conopsea is necessary to study. Meanwhile, the toxicity of this plant had not been comprehensively studied, and the active constituents and the mechanisms of action of the tuber were still unclear. Further, studies on G. conopsea should lead to the development of scientific quality control and new drugs and therapies for various diseases; thus, its use and development require additional investigation.

Abstract
Two new pyranoflavonoids, morustralins A (1) and B (2), a new natural benzene derivative, one benzenoid (Z)-1-hydroxy-4-(2-nitroethenyl)benzene (3), and thirty known compounds were isolated and characterized from the root bark of Morus australis. The structures of the new compounds were established from spectroscopic and spectrometric analyses. Ten isolates (1-10) were examined for inhibitory effects on adenosine diphosphate (ADP)-, arachidonic acid (AA)-, and platelet-aggregating factor (PAF)-induced platelet aggregation. Among the tested compounds, compound 3 displayed the most significant inhibition of ADP- and AA-induced platelet aggregation with IC50 values of 9.76±5.54 and 9.81±2.7μM, respectively. In addition, eight purified compounds (3-10) were examined for inhibition of nitric oxide (NO) production in RAW 264.7 cells and six compounds (3-8) displayed significant inhibitory effects with IC50 values ranging from 2.1±0.3 to 6.3±0.6μM.

Abstract
Chemical fractionation of the ethanolic extract generated from the twigs and leaves of Sapium discolor led to the isolation and identification of four new macrocyclic diterpenoids including three members of the rare casbane family, sapidisins A-C (1-3), and an analog of the cembrane class, sapidisin D (4), a new 3,4-seco ent-kaurane diterpenoid (5), and 18 known phenolic compounds. Their structures were elucidated by comprehensive spectroscopic analyses especially 1D NMR (1)H-(1)H couplings and 2D NMR ROESY data. The discovery of 1-4 from S. discolor provides a clue for further study on the biogenetic evolution of the widely existent tigliane-type diterpenoids in the Sapium species.

Abstract
o- and/or p-naphthoquinone methides (NQMs) can be selectively prepared by the ring opening of 1-(siloxymethyl)-1,4-epoxy-1,4-dihydronaphthalene derivatives based on a substituent effect at the 4 position of the substrates. The 4-alkyl- or silyl-substituted 1-(siloxymethyl)-1,4-epoxy-1,4-dihydronaphthalene was transformed to o-NQM (1-naphthoquinone-2-methide), which underwent Friedel-Crafts 1,4-addition of the α,β-unsaturated carbonyl moiety to provide the 2-benzyl-1-naphthol as the biarylmethane and [4 + 2]-cycloaddition with a dienophile to give the fused heterocyclic arene. Meanwhile, the 4-unsubstituted 1-(siloxymethyl)-1,4-epoxy-1,4-dihydronaphthalene could be converted to the corresponding 4-benzyl-1-naphthol by the Friedel-Crafts 1,6-addition of p-NQM (1-naphthoquinone-4-methide) generated by the site-selective ring opening of the 1,4-epoxy moiety. Furthermore, the 4-(siloxymethyl)-(1,4-bis(siloxymethyl))-1,4-epoxy-1,4-dihydronaphthalene was transformed into a 2,4-bisbenzyl-1-naphthol or pentacyclic derivative via both the o- and p-NQM intermediates.

Abstract
Rhodiola crenulata L. is an important species in genus Rhodiola widely used as a health food to reinforce immunity, improve memory and learning, scavenge active-oxygen species, and relieve altitude sickness. Eleven new lignans and a new benzonitrile compound, crenulatanoside A, were isolated from the roots of R. crenulata L. along with 25 known compounds, including 12 lignans. The structures of these compounds were elucidated by spectroscopic data and chemical evidence. Among them, compounds 1-4 and 5-7 were determined to be optical isomers of two 8-O-4' neolignan glycosides. Compounds 8-11 were aryl tetralin type lignans, and compounds 12 and 13 were dihydrobenzofuran neolignans. All of the isolated compounds were evaluated for their inhibitory activity against α-glucosidase. From the data obtained, compound 37 showed strong inhibitory activity against α-glucosidase with an IC(50) value of 96.8 μM.

Abstract
Eucomic acid [(2R)-2-(p-hydroxybenzyl)malic acid)] (1) and three new glucopyranosyloxybenzyl eucomate derivatives, vandaterosides I (2), II (3), and III (4), were isolated and identified from the stems of Vanda teres. Their cellular antiaging properties were evaluated in a human immortalized keratinocyte cell line (HaCaT) by monitoring their effect on cytochrome c oxidase activity, implicated in mitochondrial respiratory function and cellular energy production. Eucomic acid (1) and vandateroside II (3) increased cytochrome c oxidase activity and/or expression, without enhancing cellular mitochondrial content. These two V. teres biomarkers apparently contributed to stimulate respiratory functions in keratinocytes. Since aging and its pathologies may be ascribed to a decline in mitochondrial functions, these biomarkers have the potential to become new natural ingredients for antiaging preparations to remedy age-related disorders such as skin aging.

Abstract
The methanolic extract of the whole plant of Cyperus longus originating in Egypt was found to show antiallergic effect on ear passive cutaneous anaphylaxis reactions in mice. By bioassay-guided separation, 11 stilbenes and stilbene dimers including a novel norstilbene dimer, longusone A, and three new stilbene dimers, longusols A, B, and C, were isolated. Their structures were elucidated on the basis of chemical and physicochemical evidence. Among the isolates, longusol B (IC(50)=96 µM), luteolin (3.0 µM), resveratrol (17 µM), piceatannol (24 µM), and cassigarols E (84 µM) and G (84 µM) were found to inhibit the release of β-hexosaminidase, as a marker of antigen-induced degranulations, in rat basophilic leukemia (RBL-2H3) cells. In addition, the methanolic extract and the constituents showed 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity (SC(50)=22 µg/ml and 2.8-29 µM, respectively).

Abstract
The aim of this review is to survey the various naturally occurring phenanthrene compounds that have been isolated from different plants. Only one review has previously been published on this topic. Gorham (1989) reviewed the structures, biosynthesis, separations and spectroscopy of stilbenes and phenanthrenes. The present study furnishes an overview of the hydroxy or/and methoxy-substituted 9,10-dihydro/phenanthrenes, methylated, prenylated and other monomeric derivatives, dimeric and trimeric phenanthrenes and their biological activities. A fairly large number of phenanthrenes have been reported from higher plants, mainly in the Orchidaceae family, in the species Dendrobium, Bulbophyllum, Eria, Maxillaria, Bletilla, Coelogyna, Cymbidium, Ephemerantha and Epidendrum. A few phenanthrenes have been found in the Hepaticae class and Dioscoreaceae, Combretaceae and Betulaceae families. Their distribution correlates strongly with the taxonomic divisions. These plants have often been used in traditional medicine, and phenanthrenes have therefore been studied for their cytotoxicity, antimicrobial, spasmolytic, anti-inflammatory, antiplatelet aggregation, antiallergic activities and phytotoxicity. On the basis of 120 references, this review covers the phytochemistry and pharmacology of phenanthrenes, describing 252 compounds. This contribution stems from our work on the medicinal plant Tamus communis.

Abstract
The methanolic extract from the roots of Rhodiola sachalinensis was found to show a protective effect on D-galactosamine-induced cytotoxicity in primary cultured mouse hepatocytes. From the methanolic extract, five new glycosides, two monoterpene glycosides, two flavonol bisdesmosides, and a cyanogenic glycoside, were isolated together with 34 known compounds. The structures of new constituents were elucidated on the basis of chemical and physicochemical evidence. In addition, the principal constituents, sachalosides III and IV, rhodiosin, and trans-caffeic acid, displayed hepatoprotective effects.

Abstract
The methanolic extract from the whole plant of Sinocrassula indica (Crassulaceae) was found to inhibit the increase in serum glucose levels in oral administration of sucrose and glucose in rats at a dose of 250 mg/kg (p.o.). However, the extract did not inhibit the increase in serum glucose levels after intraperitoneal administration of glucose in these animals but did partly inhibit the gastric emptying. On the other hand, this extract significantly inhibited the increase in serum glucose levels after administration for 2 weeks in KK-A(y) mice, a genetically type II diabetic mice, at a dose of 250 mg/kg/d (p.o.) without significant changes of the weights of body, liver, and visceral fat. From the extract, four new acylated flavonol glycosides, sinocrassosides A(1), A(2), B(1), and B(2), were isolated together with 11 flavonoids and 2 megastigmanes. The absolute stereostructures of the four new compounds were elucidated on the basis of chemical and physicochemical evidence.

Abstract
The methanol-eluted fraction of the hot water extract from the whole plant of Sedum sarmentosum (Crassulaceae) was found to show hepatoprotective effect on D-galactosamine-induced cytotoxicity in primary cultured mouse hepatocytes. From the active fraction, five new megastigmane glycosides, sedumosides A(4), A(5), A(6), H, and I, were isolated together with 22 megastigmane constituents. Their absolute stereostructures were elucidated on the basis of chemical and physicochemical evidence. Among them, sedumoside F(1) (IC(50)=47 microM), (3S,5R,6S,9R)-megastigmane-3,9-diol (61 microM), and myrsinionosides A (52 microM) and D (62 microM) were found to show the strong hepatoprotective activity.

Abstract
The ethyl acetate-soluble fraction of the methanolic extract from the seeds of Psoralea corylifolia was found to inhibit the release of beta-hexosaminidase, as a marker of antigen-IgE-induced degranulation in RBL-2H3 cells. Sixteen constituents were isolated from the ethyl acetate-soluble fraction and several constituents, Delta(1),3-hydroxybakuchiol (IC(50) = 49 microM), Delta(3),2-hydroxybakuchiol (69 microM, bavachin (58 microM), and psoralidin (ca. 100 microM), showed inhibitory activities against the antigen-induced degranulation.

Abstract
The methanolic extract from the male flowers of Borassus flabellifer was found to inhibit the increase of serum glucose levels in sucrose-loaded rats at a dose of 250 mg/kg, p.o. From the methanolic extract, six new spirostane-type steroid saponins, borassosides A-F (1-6), were isolated together with 23 known constituents. The structures of borassosides (1-6) were elucidated on the basis of chemical and physicochemical evidences. In addition, the principal steroid saponin, dioscin (13), inhibited the increase of serum glucose levels in sucrose-loaded rats at a dose of 50 mg/kg, p.o.

Abstract
The methanolic extract from the dried stems of Cistanche tubulosa (Schrenk) R. Wight was found to show an inhibitory effect on contractions induced by noradrenaline in isolated rat aortic strips. From the extract, new phenylethanoid oligoglycoside constituents, kankanosides F and G, and an acylated oligosugar, kankanose, were isolated together with 14 known compounds. The structures of these new compounds were determined on the basis of their chemical and physicochemical evidence. In addition, principal constituents, kankanoside F, kankanose, echinacoside, acteoside, and cistanoside F, showed vasorelaxant activity, and several structural requirements for the activity were clarified.
