Major specialized natural products from the endangered plant Heptacodium miconioides, potential medicinal uses and insights into its longstanding unresolved systematic classification. PHYTOCHEMISTRY 2024; 228:114259. [PMID: 39186996 DOI: 10.1016/j.phytochem.2024.114259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/23/2024] [Revised: 08/15/2024] [Accepted: 08/23/2024] [Indexed: 08/28/2024]
Abstract
A comprehensive phytochemical investigation of the flower buds and leaves/twigs of Heptacodium miconioides, a cultivated ornamental plant native to China and categorized as 'vulnerable', has led to the isolation of 45 structurally diverse compounds, which comprise 18 phenylpropanoids (1-4, 7-20), 11 pentacyclic triterpenoids (5, 6, 21-29), eight secoiridoid glycosides (30-37), three quinic acid derivatives (38-40), and a few miscellaneous components (41-45). Among them, (+)-α-intermedianol (1), (+)-holophyllol A (2), and (-)-pseudolarkaemin A (3) represent previously unreported enantiomeric lignans, while (+)-7'(R)-hydroxymatairesinol (4) is an undescribed naturally occurring lignan. Heptacoacids A (5) and B (6) are undescribed 24-nor-urs-28-oic acid derivatives. Their chemical structures were determined by 2D-NMR, supplemented by evidence from specific rotations and circular dichroism spectra. Given the uncertainty surrounding the systematic position of Heptacodium, integrative taxonomy (ITA), a method utilized to define contentious species, is applied. Chemotaxonomy, a vital aspect of ITA, becomes significant. By employing hierarchical clustering analysis (HCA) and syntenic pattern analysis methods, a taxonomic examination based on the major specialized natural products from the flower buds of H. miconioides and two other Caprifoliaceae plants (i.e., Lonicera japonica and Abelia × grandiflora) could offer enhanced understanding of the systematic placement of Heptacodium. Additionally, compounds 39 and 40 displayed remarkable inhibitory activities against ATP-citrate lyase (ACL), with IC50 values of 0.11 and 1.10 μM, respectively. In summary, the discovery of medical properties and refining systematic classification can establish a sturdy groundwork for conservation efforts aimed at mitigating species diversity loss while addressing human diseases.

[PMID: 35896957 PMCID: PMC9327190 DOI: 10.1186/s12864-022-08727-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Accepted: 06/29/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Viola philippica Cav. is the only source plant of "Zi Hua Di Ding", which is a Traditional Chinese Medicine (TCM) that is utilized as an antifebrile and detoxicant agent for the treatment of acute pyogenic infections. Historically, many Viola species with violet flowers have been misused in "Zi Hua Di Ding". Viola have been recognized as a taxonomically difficult genera due to their highly similar morphological characteristics. Here, all common V. philippica adulterants were sampled. A total of 24 complete chloroplast (cp) genomes were analyzed, among these 5 cp genome sequences were downloaded from GenBank and 19 cp genomes, including 2 "Zi Hua Di Ding" purchased from a local TCM pharmacy, were newly sequenced. RESULTS The Viola cp genomes ranged from 156,483 bp to 158,940 bp in length. A total of 110 unique genes were annotated, including 76 protein-coding genes, 30 tRNAs, and four rRNAs. Sequence divergence analysis screening identified 16 highly diverged sequences; these could be used as markers for the identification of Viola species. The morphological, maximum likelihood and Bayesian inference trees of whole cp genome sequences and highly diverged sequences were divided into five monophyletic clades. The species in each of the five clades were identical in their positions within the morphological and cp genome tree. The shared morphological characters belonging to each clade was summarized. Interestingly, unique variable sites were found in ndhF, rpl22, and ycf1 of V. philippica, and these sites can be selected to distinguish V. philippica from samples all other Viola species, including its most closely related species. In addition, important morphological characteristics were proposed to assist the identification of V. philippica. We applied these methods to examine 2 "Zi Hua Di Ding" randomly purchased from the local TCM pharmacy, and this analysis revealed that the morphological and molecular characteristics were valid for the identification of V. philippica. CONCLUSIONS This study provides invaluable data for the improvement of species identification and germplasm of V. philippica that may facilitate the application of a super-barcode in TCM identification and enable future studies on phylogenetic evolution and safe medical applications.

Abstract
Polygonaceae is a large family of medicinal herbs that includes many species used as traditional Chinese medicine, such as Persicaria perfoliate. Here, we sequenced the complete cp genome of P. perfoliata using Illumina sequencing technology with the purpose to provide a method to facilitate accurate identification. After being annotated, the cp genome of P. perfoliata was compared with Fagopyrum tataricum, Persicaria chinensis, Fagopyrum dibotrys and Fallopia multiflora. The complete cp genome of P. perfoliata is 160,730 bp in length, containing a small single copy (SSC) region of 12,927 bp, a large single copy (LSC) region of 85,433 bp and a pair of inverted repeats (IR) regions of 62,370 bp. A total of 131 genes were annotated, including eight rRNA genes, 34 tRNA genes and 84 protein-coding genes. Forty-two simple sequence repeats and fifty-five repeat sequences were identified. Mutational hot spots analyses indicated that five genes (matK, ndhF, ccsA, cemA, rpl20) could be selected as candidates for molecular markers. Moreover, phylogenetic analysis showed that all the Polygonaceae species formed a monophyletic clade, and P. perfoliata showed the closest relationship with P. chinense. The study provides valuable molecular information to accurately identify P. perfoliata and assist in its development and application.

Abstract
Polygonati rhizoma (Huangjing in Chinese) is a traditional and classic dual-purpose material used in food and medicine. Herbalists in China and Japan have noticed several different rhizome types in Huangjing with different qualities. Rhizome of Polygonatum cyrtonema Hua and P. sibiricum Red. is divided into five types: "Jitou-type" Polygonati rhizoma (JTPR), atypical "Jitou-type" Polygonati rhizoma (AJTPR), "Jiang-type" Polygonati rhizoma (JPR), "Cylinder-type" Polygonati rhizoma (CPR), and "Baiji-type" Polygonati rhizoma (BJPR). This study observed the microstructure and histochemical localization of polysaccharides, saponins, and proteins in Huangjing. Nutritional and medicinal component data and antioxidant capacity (DPPH and ABTS) were analyzed to evaluate the quality of different types of Huangjing. The results showed that the comprehensive quality of the rhizomes, BJPR and JTPR, was better, regardless of their nutritional or medicinal values. Altogether, these results could recommend future breeding efforts to produce Huangjing with improved nutritional and medicinal qualities.

Abstract
Proanthocyanidins are natural glycosidase inhibitors with excellent antioxidant activity. This study aims to search for a new source of proanthocyanidins for the prevention and treatment of type 2 diabetes with higher content and better activity and get their structure elucidated. First, the total proanthocyanidins contents (TOPCs), antioxidant activity, antidiabetic activity of seven common Polygonaceae plants were analyzed and compared. Then proanthocyanidins from the rhizome of Fagopyrum dibotrys were purified, and the detailed structure was comprehensively analyzed by ultraviolet visible spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FT-IR), 13C nuclear magnetic resonance spectroscopy (13C NMR), reversed-phase high-performance liquid chromatography-electrospray mass spectrometry (RP-HPLC-ESI-MS), and matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS). The rhizome of F. dibotrys showed the highest TOPCs, the strongest antioxidant, and antidiabetic activities; the TOPCs, antioxidant and antidiabetic activities were all very significantly positively correlated. Proanthocyanidins purified from the rhizome of F. dibotrys showed better antidiabetic activity than grape seed proanthocyanidins (GsPs). Seventy-two proanthocyanidins from trimer to undecamer with a mean degree of polymerization (mDP) of about 5.02 ± 0.21 were identified with catechin and epicatechin as the dominant monomers. Conclusion: Proanthocyanidins are the main antioxidant and antidiabetic active substances of F. dibotrys and are expected to be developed into potential antioxidant and hypoglycemic products.

Abstract
Heshouwu, derived from root tubers of Fallopia multiflora (Thunb.) Harald., is a well-known herb used for millennia in traditional Chinese medicine. However, different forms of root tubers of Heshouwu have occurred in current Chinese herbal market and used in clinic, although it is still unknown whether their quality is consistent. In the present study, a mass spectrometry imaging and laser microdissection combined with UPLC-Q/TOF-MS were therefore used for the metabolite profiling on the whole and different parts of root tubers of F. multiflora and F. multiflora var. angulata. Our results suggested that the character of "woody heart" root tubers of F. multiflora was similar to that of F. multiflora var. angulata, but the latter had more phloem fibers and larger diameter vessel in the normal vascular bundle. Moreover, 140 compounds including stilbenes, anthraquinones, phenolic acids, naphthalenes, and other compounds were identified or putatively characterized from F. multiflora and F. multiflora var. angulata. Both unsupervised principal component analysis (PCA) and supervised Orthogonal Partial Least Squares Discrimination Analysis (OPLS-DA) multivariate statistics allowed discriminating F. multiflora and F. multiflora var. angulata. And a total of 32 potential markers were identified. The tissue-specific study indicated that the compounds in the phelloderm of F. multiflora and F. multiflora var. angulata were the most abundant. This is the first study on metabolite profiling and comparison of root tubers between F. multiflora and F. multiflora var. angulata, which would provide reasonable basis for further quality evaluation and safe medication of F. multiflora.
