Taxonomic and phylogenetic study of the subgenus Tricercandra in the genus Chloranthus</o> (Chloranthaceae)

The genus Chloranthus consists of 17 taxa with the two subgenera Chloranthus and Tricercandra. These two subgenera can be distinguished by the morphology of the androecium. In South Korea, C. japonicus and C. fortunei of the subgenus Tricercandra are distributed. Although C. fortunei is typically not branched, a variant that branches from the stem has recently been discovered. Here, we conducted morphological and molecular phylogenetic analyses to elucidate the interspecific relationships within the subgenus Tricercandra and to evaluate the taxonomic position of the variant of C. fortunei. Morphological analyses revealed distinct differences among C. angustifolius, C. japonicus, C. fortunei, and the variant of C. fortunei. However, distinguishing between C. holostegius and C. nervosus was challenging. A principal component analysis also showed that while C. angustifolius, C. japonicus, C. fortunei, and the corresponding variant clustered independently, C. holostegius and C. nervosus overlapped, rendering them indistinguishable. Molecular phylogenetic studies using nuclear ribosomal internal transcribed spacer (nrITS) regions and three plastid regions, rbcL, rpl20-rps12, and trnL-F, revealed that the subgenus Tricercandra was monophyletic. Within the subgenus Tricercandra, C. angustifolius formed a sister clade with C. fortunei in the combined three plastid gene tree, while C. japonicus displayed different phylogenetic relationships between the nrITS and plastid gene trees. In addition, neither C. holostegius nor C. nervosus was monophyletic, consistent with the morphological analyses. The variant of C. fortunei formed an independent subclade on the nrITS tree but was not distinguished from other C. fortunei on the plastid gene tree. Our study elucidated clear species delimitation among C. angustifolius, C. japonicus, and C. fortunei and suggested key morphological characters useful for distinguishing them. Furthermore, our findings highlighted the ambiguous species delimitation and phylogenetic uncertainty between C. holostegius and C. nervosus. While we demonstrated morphological differences between the typical C. fortunei and its variant, the limited molecular phylogenetic evidence implies a need for further study.

Terpenoids from the roots of Chloranthus henryi Hemsl. var. hupehensis (Pamp.) K. F. Wu and their chemotaxonomic significance

Phytochemical research on the roots of Chloranthus henryi Hemsl. var. hupehensis (Pamp.) K. F. Wu afforded twenty-three terpenoids, including twenty-two sesquiterpenoids (1–22) and one diterpenoid (23). Their structures were identified by extensive spectroscopic analysis and comparison with literature data. Among them, six sesquiterpenoids (2, 3, 13–16) were first obtained from the family Chloranthaceae, two sesquiterpenoids (4 and 5) were first reported from the genus Chloranthus, and all the twenty-three terpenoids were isolated for the first time from the investigated plant. Moreover, the chemotaxonomic significance of constituents was also discussed.

Preliminary phytochemical screening of medicinal herb, SAMBAU PAYA (Chloranthus erectus)

The genus Chloranthus (L.) is one of the most important groups of plants belonging to the Chloranthaceae family. Chloranthus erectus is an erect shrub, native to Southeast Asia's tropical and temperate zones. It is a popular folklore medicine used by many indigenous communities. However, no comprehensive assessment and scientific report of C. erectus were published. Hence, this preliminary study was carried out to screen the phytochemical analysis of leaves extract in methanol and aqueous extracts of indigenous medicinally important plants of C. erectus. The phytochemicals analysis reveals the presence of alkaloids, flavonoids, terpenoids, saponins, quinones, glycosides, and steroids. The current study shows that C. erectus solvent extract contains therapeutically significant bioactive components, which supports the use of plant species as traditional medicine for the treatment of a variety of disorders.

Among them, the main chemical constituents are sesquiterpenes and their diterpenoids. Modern pharmacological studies have shown that most of the Chloranthus plants possessed anti-cancer, anti-inflammatory, antibacterial, antiviral, and antimalarial activities. As one of the most important genera in China, Chloranthus should be paid further attention to gathering information about the pharmacological mechanism and value active compounds. This paper summarized the phytochemistry, pharmacology, and uses of genus Chloranthus in order to lay a foundation and provide reference for the follow-up research and wide application of the genus.

The complete plastid genome sequence of Chloranthus fortunei (A. Gray) Solms-Laub. in Chloranthaceae

Chloranthus fortunei (A. Gray) Solms-Laub. is a perennial herb in a basal angiosperm family Chloranthaceae. Here, we reported the complete plastid genome of C. fortunei using Illumina short-read data. The total genome size was 157,063 bp in length, containing 79 protein-coding genes, 30 tRNA genes, and four rRNA genes. The gene content and order were consistent with previously reported Chloranthus plastid genomes. The overall GC content of the C. fortunei plastid genome was 39.0%. In the phylogenetic result, genus Chloranthus was monophyletic and divided into two subclades: C. japonicus+C. angustifolius+C. fortunei, and C. henryi+C. spicatus+C. erectus. Our phylogenetic result was consistent with previous phylogenetic studies, and was supported by a previously proposed infrageneric classification of the genus Chloranthus.

In vitro inhibitory properties of sesquiterpenes from Chloranthus serratus on cell motility via down-regulation of LIMK1 activation in human breast cancer

BackgroundLIM kinase 1 plays an important role in tumor cell invasion and metastasis by regulating architecture of actin cytoskeleton, and inhibiting activity of this kinase may be a promising strategy to prevent cancer cells from distant spread. In our previous studies, we found several extracts from the medical herbs in genus Chloranthus to exhibit anti-metastatic effects. PurposeThe aim of this study is to find LIMK1 inhibitors from Chloranthus serratus, a medical herb from genus Chloranthus and to evaluate their effects on cell motility. MethodsThree sesquiterpenes, chloranthalactone E (compound 1), serralactone A (compound 2, SERA is used in the further testing), and 8β, 9α-dihydroxylindan-4(5), 7(11)-dien-8α, 12-olide (compound 3) were isolated from Chloranthus serratus, and the anti-LIMK1 activities of these compounds were investigated by kinase-Glo® luminescent kinase assay. Then, the anti-LIMK1 properties of SERA were verified by kinase-Glo® luminescent kinase assay and western blot assay. The effects of SERA on F-actin polymerization and cell migration were investigated by Phalloidin dying, AP 48 chamber system and ORIS™ cell migration assay. Furthermore, the inhibitory effects of SERA on LIMK1 were confirmed by overexpression of LIMK1 and small interfering RNA (siRNA) mediated gene silencing. Resultswe reported here that among the three sesquiterpenes, SERA showed significantly inhibition on LIMK1 activity, and the IC50 values on MDA-MB-231 and MDA-MB-468 cells were 3.14 μM and 4.64 μM, respectively. Furthermore, it was also found that SERA significantly suppressed LIMK1 and cofilin1 phosphorylation, F-actin polymerization and also cell migration. Data from LIMK1 overexpression and RNA interfering assay confirmed that the inhibitory effects of SERA on LIMK1 was antagonized and enhanced by the overexpression and knockdown of LIMK1. Conclusioncollectively, it was concluded that SERA exhibited significant inhibitory effects on breast cancer cells migration, and these effects of this sesquiterpene are due to its properties reducing the activation of LIM kinase 1.

Secondary metabolites of plants from the genus chloranthus: chemistry and biological activities.

Chloranthus, a genus of the family Chloranthaceae, which is mainly distributed in eastern and southern Asia, has been used in Chinese folk medicine due to its antitumor, antifungal, and anti-inflammatory activities. This review compiles the research on isolation, structure elucidation, structural diversity, and bioactivities of Chloranthus secondary metabolites reported between 2007 and 2013. The metabolites listed encompass 82 sesquiterpenoids, 50 dimeric sesquiterpenoids, 15 diterpenoids, one coumarin, and five other compounds. Among them, dimeric sesquiterpenoids, the characteristic components of plants from the genus Chloranthus, have attracted considerable attention due to their complex structures and significant biological features, e.g., antitumor, antibacterial, antifungal, anti-inflammatory, and hepatoprotective activities, and potent and selective inhibition of the delayed rectifier (IK) K(+) current and tyrosinase.

Chloranthus_like Stamens from the Upper Cretaceous of New Jersey

Chloranthus_like Stamens from the Upper Cretaceous of New Jersey

CHLORANTHUS‐LIKE STAMENS FROM THE UPPER CRETACEOUS OF NEW JERSEY

Fossil angiospermous stamens with in situ pollen from the Turonian (ca. 90 million years before present, Late Cretaceous) of New Jersey are described and assigned to the Chloranthaceae. The fossil stamens, which are three‐parted and bear two bisporangiate thecae on the central lobe and one bisporangiate theca on each lateral lobe, are indistinguishable from stamens of several extant species of Chloranthus. The pollen is spheroidal, 13–18 μm in diameter, with a reticulate exine and apparently elongate/elliptical apertures. The pollen is similar to that in extant Chloranthus in grain size, shape, exine sculpture, and aperture structure. Like pollen of some extant species of Chloranthus, aperture number in the fossil pollen appears to be variable. Because fossil pistillate chloranthoid reproductive structures have not been found at this locality it is unknown whether the fossil stamens described here were borne on the side of the ovary, as in extant Chloranthus, or in another arrangement. The three‐parted stamen of Chloranthus is unique in angiosperms and there has been considerable debate concerning the origin and evolutionary significance of the structure. Uncertainty as to whether the three‐parted stamen represents a synapomorphy for the genus or a retained plesiomorphy in angiosperms is the primary reason why these fossil stamens are not assigned to the extant genus Chloranthus.
