A Comprehensive Review on Pharmacological Activities of Pachypodol: A Bioactive Compound of an Aromatic Medicinal Plant Pogostemon Cablin Benth. Molecules 2023; 28:molecules28083469. [PMID: 37110702 PMCID: PMC10141922 DOI: 10.3390/molecules28083469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 03/29/2023] [Accepted: 04/11/2023] [Indexed: 04/29/2023] Open
Abstract
As is well known, plant products have been increasingly utilized in the pharmaceutical industry in recent years. By combining conventional techniques and modern methodology, the future of phytomedicines appears promising. Pogostemon Cablin (patchouli) is an important herb used frequently in the fragrance industries and has various therapeutic benefits. Traditional medicine has long used the essential oil of patchouli (P. cablin) as a flavoring agent recognized by the FDA. This is a gold mine for battling pathogens in China and India. In recent years, this plant has seen a significant surge in use, and approximately 90% of the world's patchouli oil is produced by Indonesia. In traditional therapies, it is used for the treatment of colds, fever, vomiting, headaches, and stomachaches. Patchouli oil is used in curing many diseases and in aromatherapy to treat depression and stress, soothe nerves, regulate appetite, and enhance sexual attraction. More than 140 substances, including alcohols, terpenoids, flavonoids, organic acids, phytosterols, lignins, aldehydes, alkaloids, and glycosides, have been identified in P. cablin. Pachypodol (C18H16O7) is an important bioactive compound found in P. cablin. Pachypodol (C18H16O7) and many other biologically essential chemicals have been separated from the leaves of P. cablin and many other medicinally significant plants using repeated column chromatography on silica gel. Pachypodol's bioactive potential has been shown by a variety of assays and methodologies. It has been found to have a number of biological activities, including anti-inflammatory, antioxidant, anti-mutagenic, antimicrobial, antidepressant, anticancer, antiemetic, antiviral, and cytotoxic ones. The current study, which is based on the currently available scientific literature, intends to close the knowledge gap regarding the pharmacological effects of patchouli essential oil and pachypodol, a key bioactive molecule found in this plant.

Fontana G, Bruno M, Sottile F, Badalamenti N. The Chemistry and the Anti-Inflammatory Activity of Polymethoxyflavonoids from Citrus Genus. Antioxidants (Basel) 2022; 12:antiox12010023. [PMID: 36670885 PMCID: PMC9855034 DOI: 10.3390/antiox12010023] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 12/15/2022] [Accepted: 12/21/2022] [Indexed: 12/24/2022] Open
Abstract
Polymethoxyflavonoids (PMFs) are a large group of compounds belonging to the more general class of flavonoids that possess a flavan carbon framework decorated with a variable number of methoxy groups. Hydroxylated polymethoxyflavonoids (HPMFs), instead, are characterized by the presence of both hydroxyl and methoxy groups in their structural unities. Some of these compounds are the aglycone part in a glycoside structure in which the glycosidic linkage can involve the -OH at various positions. These compounds are particular to Citrus genus plants, especially in fruits, and they are present mainly in the peel. A considerable number of PMFs and HPMFs have shown promising biological activities and they are considered to be important nutraceuticals, responsible for some of the known beneficial effects on health associated with a regular consumption of Citrus fruits. Among their several actions on human health, it is notable that the relevant contribution in controlling the intracellular redox imbalance is associated with the inflammation processes. In this work, we aim to describe the status concerning the chemical identification and the anti-inflammatory activity of both PMFs and HPMFs. In particular, all of the chemical entities unambiguously identified by isolation and complete NMR analysis, and for which a biochemical evaluation on the pure compound was performed, are included in this paper.

Pharmaceuticals (Basel) 2021; 14:ph14090917. [PMID: 34577616 PMCID: PMC8469486 DOI: 10.3390/ph14090917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 09/03/2021] [Accepted: 09/08/2021] [Indexed: 12/01/2022] Open
Abstract
Coccoloba cowellii Britton (Polygonaceae, order Caryophyllales) is an endemic and critically endangered plant species that only grows in the municipality of Camagüey, a province of Cuba. A preliminary investigation of its total methanolic extract led to the discovery of promising antifungal activity. In this study, a bioassay-guided fractionation allowed the isolation of quercetin and four methoxyflavonoids: 3-O-methylquercetin, myricetin 3,3′,4′-trimethyl ether, 6-methoxymyricetin 3,4′-dimethyl ether, and 6-methoxymyricetin 3,3′,4′-trimethyl ether. The leaf extract, fractions, and compounds were tested against various fungi and showed strong in vitro antifungal activity against Cryptococcus neoformans and various Candida spp. with no cytotoxicity (CC50 > 64.0 µg/mL) on MRC-5 SV2 cells, determined by a resazurin assay. A Candida albicans SC5314 antibiofilm assay indicated that the antifungal activity of C. cowellii extracts and constituents is mainly targeted to planktonic cells. The total methanolic extract showed higher and broader activity compared with the fractions and mixture of compounds.

Phenolic Fingerprinting, Antioxidant, and Deterrent Potentials of Persicaria maculosa Extracts. Molecules 2020; 25:molecules25133054. [PMID: 32635342 PMCID: PMC7411858 DOI: 10.3390/molecules25133054] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Revised: 06/30/2020] [Accepted: 07/02/2020] [Indexed: 02/02/2023] Open
Abstract
Persicaria maculosa (Polygonaceae) (known as lady’s thumb) is an annual morphologically variable weed that is widely distributed in Chile. The purpose of this study was to investigate the antifeedant potential of methanolic (MeOH), ethanolic (EtOH), and dichloromethane (DCM) extracts from the aerial parts of this plant collected in the Valparaíso and Curicó provinces (Chile) and relate this activity to the antioxidant capacity and the presence of phenolic compounds in the extracts. A phenolic profile based on HPLC-ESI-MS/MS allowed the identification of 26 phenolic compounds, most of them glycosyl derivatives of isorhamnetin, quercetin, and kaempferol. In addition, the total phenolic content (TP), total flavonoids (TF), and antioxidant activity measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide anion scavenging (O2−), ferric-reducing antioxidant power (FRAP), and cupric-reducing antioxidant capacity (CUPRAC) of the extracts are reported. The antifeedant potentials of the plant extracts were tested against Epilachna paenulata, Pseudaletia adultera, Macrosiphum euphorbiae, and Diaphorina citri insects for the first time. The activity against the aphid M. euphorbiae was significant for the DCM extracts of plants from Valparaíso and Curicó (settling % = 23% ± 4% and 23% ± 5%, respectively). The antifeedant activities against the beetle E. paenulata and the lepidoptera P. adultera were significant for Valparaíso extracts, especially when tested against E. Paenulata (IFP = 1.0 ± 0.0). Finally, the MeOH and EtOH extracts from Valparaíso plants reduced the diet consumption of the psilid D. citri (p < 0.05). The results showed that P. maculosa is a good source of flavonoids with some antioxidant capacities and has potential interest as botanical eco-friendly alternative with deterrent activity.

Abstract
A series of 11 flavonol glucuronides were isolated from the herb of Polygonum aviculare L. (Ph.Eur) of which 8 were reported for the first time from the Polygonum species. Three acetylated kaempferol and isorhamnetin glucuronides were isolated from a natural source for the first time. All compounds, including the new ones, were characterized using 1D and 2D NMR spectra as well as high resolution mass spectrometry. The influence of all isolated compounds on the production of reactive oxygen species, as well as on elastase release by human neutrophils, was evaluated in in vitro studies. The results showed that all investigated compounds at physiologically achievable concentrations within the range of 0.5-10 μM significantly inhibited the production of reactive oxygen species as well as elastase release in human neutrophils model and should be considered as responsible for anti-inflammatory activity of the P. aviculare herb. The chemotaxonomic value of isolated compounds was also discussed.

Abstract
Obesity is a chronic, costly disease, and flavonoids such as quercetin have been proven to play protective roles against it. This study investigated the suppressive effect of quercetin-3-O-(6″-feruloyl)-β-D-galactopyranoside (QFG) on adipogenesis of 3T3-L1 preadipocytes. Quercetin-3-O-(6″-feruloyl)-β-D-galactopyranoside and quercetin were both extracted from Psidium guajava (Myrtaceae, commonly known as guava) leaves and were evaluated for their suppressive effect on adipogenesis by means of oil red O staining and triglyceride assay. It was shown that QFG inhibited adipogenesis in a dose- and time-dependent manner, and it exerted a stronger effect than did quercetin at the same concentration. Quantitative real-time polymerase chain reaction and western blotting were conducted to further examine the differentiation expression of marker genes and transcriptional factors. Both mRNA and protein expression of the key adipogenic transcriptional factors, peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT (cytidine-cytidine-adenosine-adenosine-thymidine)/enhancer-binding protein alpha (C/EBPα), were inhibited by QFG. Moreover, the mRNA expression patterns of key participants in the Wnt-β-catenin pathway were not altered during the QFG-induced adipogenesis inhibition. These results suggest that QFG effectively suppresses adipogenesis and that it exerts its role mainly through the significant down-regulation of PPARγ and C/EBPα and, probably, via a Wnt-β-catenin independent pathway.

Abstract
In our screening program for natural products that increase DR5 (death-receptor 5) expression, nine new cycloartane triterpenes, combretanones A-G (1-7), combretic acid A (8), and combretic acid B (9), were isolated from a MeOH extract of Combretum quadrangulare leaves. The known oleanane triterpenes (10, 11) and six known flavonols (12-17) were also isolated. The structures of 1-9 were elucidated by spectroscopic studies. Compounds 7, 9, 12, 16, and 17 enhanced DR5 expression, and 16 showed TRAIL-resistance abrogating activity.

Abstract
Two Bangladeshi Polygonum species, P. barbatum (L.) Hara var. barbata (common
name ?bekhanjabaj?) and P. stagninum Buch.-Ham. ex Meissn. (common name
?ratooti sag? or ?bara bishkatali?), are perennial herbs of the family
Polygonaceae. The genus Polygonum L. is well-known for its use in oriental
traditional medicine systems for the treatment of various ailments including
fever, pain, inflammation, infections, cancer and tumors. The extracts of P.
barbatum var. barbata and P. stagninum were assessed for potential antitumor
properties using the potato disc assay. All extracts showed a considerable
level of potential antitumor activity. The petroleum ether extract of P.
barbatum var. barbata and the n-hexane and ethyl acetate extracts of P.
stagninum, having IC50 values of 290, 200 and 180 ?g/disc, respectively, were
the most active among the extracts. The methanol extracts of both plants were
the least active and had an IC50 value of >400 ?g/disc. Overall, the extracts
of P. stagninum showed better antitumor activity potential than the extracts
of P. barbatum var. barbata.

Abstract
The n-hexane, ethyl acetate (EtOAc), and methanol extracts of the aerial parts of Polygonum stagninum Buch.-Ham. ex Meissn. (Polygonaceae), a Bangladeshi medicinal plant, were assessed for analgesic and anti-inflammatory properties in experimental mice and/or rat models. In the acetic-acid-induced writhing test in mice, all extracts displayed a dose dependent analgesic effect. The most potent analgesic activity was observed with the EtOAc extract at the dose of 400 mg/kg body weight, with an inhibition of writhing response of 50.3% compared to 62.2% for the positive control aminopyrine. Among the extracts, n-hexane extract at the doses of 200 and 400 mg/kg body weight showed the highest levels of anti-inflammatory activity after 2 h, with the inhibition of paw edema of 60.1% and 64.1%, respectively, and this effect was much better than that of the conventional anti-inflammatory agent phenylbutazone (maximum inhibition of 38.3% after 4 h).

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Polygonum acuminatum Kunth. (Polygonaceae) is used to heal infected wounds and as antifungal in the traditional Argentinean medicine. AIM OF THE STUDY The present investigation was carried out to evaluate the antifungal properties of aerial parts of Polygonum acuminatum, in order to give support to its ethnopharmacological use as antifungal agent and to isolate the compound(s) responsible for the antifungal properties. The influence of the plant part used, the season of the year and a study of the correlation of the antifungal activity with the content of the main active constituent were investigated too, with the aim of contributing to determine the most suitable plant extract and season of the year for achieving the best antifungal properties for Polygonum acuminatum traditional use. MATERIALS AND METHODS For the antifungal evaluation, the microbroth dilution assay recommended by the Clinical and Laboratory Standards Institute (CLSI, formerly NCCLS) was used against a panel of human opportunistic and pathogenic fungi. Bioassay-guided fractionation allowed us to isolate the compounds responsible for the antifungal activity. GC-MS was used to quantify the main component in the different extracts. For the statistical analysis, ANOVA test for analyses of variance followed by the Tukey test of Multiple Comparisons were used. The correlations between content of the antifungal compound and antifungal activity, were calculated with the Spearman Correlation Coefficient. RESULTS Aerial parts (A) of Polygonum acuminatum showed to possess antifungal properties against yeasts as well as dermatophytes but not against Aspergillus spp. From the most active extract (ADCM), polygodial, isopolygodial, drimenol and confertifolin were isolated, possessing polygodial a broader spectrum of action and lower MICs than the rest of compounds. Among the different parts, leaves (L), stems (S) and fruits (F), that constitute the aerial parts of Polygonum acuminatum, (L) showed to possess the best activities, compared to (S) and (F). The analysis of the content of polygodial in the LHex, LDCM, LEtOAC, LMeOH extracts collected in Summer, Autumn, Winter and Spring showed that LDCM of all seasons possessed higher percentages of this sesquiterpene than the rest of extracts. Among the LDCM of different seasons, that of Autumn was the most concentrated in polygodial. The correlation between content of polygodial with antifungal behavior of the different extracts, showed that LDCM of Autumn contains the highest content of polygodial and concomitantly the lowest MICs. CONCLUSION The ethnopharmacological use of Polygonum acuminatum aerial parts in the Argentinean traditional medicine for ailments related to fungal infections is supported by the results obtained in this investigation. From the obtained results, LDCM of Autumn, possessing the highest content of polygodial and the lowest MICs, appeared to be the most suitable extract for being used as antifungal in the traditional medicine. Nevertheless, if some other plant collection of another season different from Autumn is available, a LDCM extract would be the better option, because it contains a higher amount of polygodial compared to LHex, LEtOAc or LMeOH and therefore, a better antifungal activity can be expected.

Abstract
The antimicrobial activity of methanol and acetone extracts of Butomus umbellatus, Polygonum amphibium, and two species of the genus Sparganium (S. erectum and S. emersum) against three Gram-positive, five Gram-negative bacteria and one fungus was assessed by the disk diffusion method. The microorganisms used were Staphylococcus aureus ATCC-29740,Escherichia coli ATCC-25922, Pseudomonas aeruginosa ATCC-15442, Salmonella typhi NCTC-9394, Klebsiella pneumoniae NCTC-5046, Proteus vulgaris ATCC-7829, Bacillus subtilis ATCC-6633, Corynebacterium diphteriae RSHM-633 and Candida albicans ATCC-10231. Methanol extracts of the plants did not exhibit any inhibitory activity against any of the microorganisms, while the acetone extracts of the all tested plants only showed significant activity against Bacillus subtilis, with inhibition zones and minimal inhibitory concentration values in the 7-16 mm and 0.49-12.50 mg/mL ranges, respectively.

Abstract
The reversed-phase HPLC analysis of a methanol extract of the aerial parts of Cuscuta reflexa afforded a non-separable mixture (55 : 45) of two novel tetrahydrofuran derivatives, named swarnalin (1) and cis-swarnalin (2), and a known coumarin, 5,6,7-trimethoxycoumarin (3). The structures of the compounds were elucidated unequivocally by UV, HRFABMS and a series of 1D and 2D NMR analyses. The mixture of 1 and 2 showed significant free radical scavenging activity in the DPPH assay and the RC50 value was found to be 3.80 x 10(-4) mg mL(-1) for the mixture, compared to 2.88 x 10(-5) mg mL(-1) for the positive control, quercetin.

Abstract
Xylocarpus granatum J. König (Meliaceae), commonly known as 'dhundul', is a Bangladeshi mangrove tree, and well distributed in a number of other countries of south-east Asia, Australia and east Africa. Traditionally, X. granatum has been used as an astringent and febrifuge, and also for the treatment of fever, malaria, thrush, cholera, dysentery and diarrhoea in many countries including Bangladesh. Two limonoids, gedunin and 1alpha-hydroxy-1,2-dihydrogedunin, the latter being new, have been isolated from the bark of Xylocarpus granatum by reversed-phase preparative HPLC, and the structures were confirmed by spectroscopic means. The cytotoxic potential of gedunin has been evaluated by the Promega's CellTiter 96 non-radioactive cell proliferation assay using the CaCo-2 colon cancer cell line (IC(50) = 16.83 microM). A summary of the biological activities of gedunin reported to date is also presented.

Abstract
The homoisoflavanone 5,7-dihydroxy-6-methoxy-3-(9-hydroxy-phenylmethyl)-chroman-4-one (1) and its structurally related 2',4',6'-trihydroxy-3'-methoxy-alpha-hydroxymethyl-beta-hydroxy-dihydrochalcone (2) along with the known pashanone (3), flavokawin B (4) and cardamonin or alpinetin chalcone (5) pinostrobin (6) and 5,8-dimethoxy-7-hydroxychroman-4-one (7) were isolated from dry leaves of Polygonum ferrugineum (Polygonaceae). To our knowledge, this is the first report of the isolation of a homoisoflavanone from the Polygonum genus and the Polygonaceae family, and could be an important chemotaxonomic finding. In addition, the pattern of substitution of this homoisoflavanone is different from others previously reported.

Abstract
Three clerodane diterpenoids, premnones A-C (1-3), were isolated from a chloroform-soluble fraction of Premna tomentosa along with four known flavonoids and three known triterpenoids. Among these isolates, premnones A-C exhibited cytotoxic activity when evaluated against a small panel of tumor cell lines. However, premnone A was found to be inactive when evaluated in a follow-up in vivo hollow fiber assay at the highest dose tested (50mg/kg), using LNCaP, Lu1, and MCF-7 cells.

Abstract
An efficient and rapid protocol for in vitro induction and complete plant regeneration of Polygonum multiflorum THUNB has been developed. Nodal explants were grown in vitro on Murashige and Skoog's (MS) basal medium containing different concentrations of alpha-naphthaleneacetic acid (NAA) and benzyladenine (BA). The nodal explants (97%) produced multiple shoots (4.7 shoots per explant) on MS basal medium supplemented with 0.2 mg/l NAA and 2.0 mg/l BA after 6 weeks of culture. Eighty-eight percent to 100% of the shoots (1.0 cm in length) elongated (about 3.02-4.28 cm) and rooted on MS basal medium supplemented with NAA or indole-3-butyric acid (IBA). All the rooted shoots were transferred to pots containing autoclaved soil, vermiculite, and peat moss (1 : 1 : 1). The plantlets were successfully acclimatized under greenhouse conditions with high humidity before transferring to the field. The anthraquinone contents were determined using HPLC. Analysis revealed that the contents of the major medicinal compounds-emodin and physcion in the 6 weeks old in vitro grown shoots and three month old in vitro propagated plants grown in greenhouse were higher than those of the marketed crude drug (processed underground or stem parts of P. multiflorum).
