Abstract
Mesona chinensis, in Thai called Chao Kuay and in Chinese Hsian-tsao, belongs to the Lamiaceae family. This herbal plant grows widely in Southern China, Taiwan (China), Malaysia, the Philippines, Indonesia, Vietnam, and Thailand. The Mesona plant is used to make functional products such as drinks and soft textured sweet treats, and also traditional medicine, to treat heat stroke, high blood pressure, heart attack, high blood sugar, hepatic diseases, colon diseases, inflammatory conditions, and to alleviate myalgia. The proximate composition of M. chinensis is a mixture of protein, fat, fiber, ash, and minerals. The main biological compounds in M. chinensis extracts are polysaccharides, terpenoids, flavonoids, and polyphenols, with wide-ranging pharmacological properties including antioxidant, antidiabetic, antilipidemic, carcinoma-inhibitory, renal-protective, antihypertensive, DNA damage-protective, and anti-inflammatory effects. This review investigated the proximate composition, polysaccharide type, and pharmacological properties of M. chinensis extracts. Phytochemical properties enhance the actions of the gut microbiota and improve health benefits. This review assessed the functional and medicinal activities of M. chinensis extracts. Future studies should further elucidate the in vitro/in vivo mechanisms of this plant extract and its impact on gut health.

Abstract
Mesona chinensis is a common medicinal and edible plant in the Lingnan region of China, which has extensive pharmacological activity. However, the study of its chemical constituents is not sufficient. In this study, a variety of modern chromatographic separation techniques were used to isolate two compounds from 95% ethanol extract of the grass parts of M. chinensis. Their absolute configurations were determined by ultraviolet spectroscopy(UV), infrared spectroscopy(IR), high resolution mass spectrometry(HR-ESI-MS), 1D and 2D nuclear magnetic resonance(1D NMR and 2D NMR), and single-crystal X-ray diffraction(SC-XRD). Specifically, they were two new benzoyl-sesquiterpenes and named mesonanol A and mesonanol B, respectively. The results of the pharmacological activity evaluation showed that neither of the two new compounds showed obvious antiviral and anti-inflammatory activities.

Abstract
Starch is a major dietary carbohydrate, but its digestion properties need to be improved. Mesona chinensis polysaccharides (MCPs) had a unique function in improving the flocculation performance of starch. This study investigated the effects of adding Mesona chinensis polysaccharide extracted from wet fresh and dry plants with one-year storage, namely WMCP and DMCP, on the physicochemical properties and digestion kinetics of corn starch(CS). The composition analysis showed both WMCP and DMCP were an acidic heteropolysaccharide rich in galacturonic acid and galactose, whereas showed different average main fraction molecular weights (Mw) of 47.36 kDa and 42.98 kDa, respectively. In addition, WMCP showed higher yield, purity and better physicochemical properties to CS than DWCP. Thermal analysis showed WMCP decreased more gelatinization temperatures and enthalpy of CS, and increased more freeze-thaw stability, water holding capacity, and textural parameters of CS gels than DMCP. Structural analysis revealed WMCP induced more changes in crystallinity, short-range order, and microstructure of CS, which inhibited retrogradation than DMCP. In vitro digestion assays demonstrated WMCP addition significantly increased higher resistant starch content by altering starch-starch and starch-MCP interactions than DWCP. Overall, MCPs addition beneficially modulated CS properties and digestion kinetics, providing a novel way to improve starch functionalities. Moreover, WMCP had more advantages to be chosen to form hydrocolloid with CS than DMCP.

Abstract
The aim of this study was to investigate the stability and antioxidant activity of the polyphenols from Mesona chinensis Benth extract (MCE) and its alginate-based encapsulation by extrusion technique during simulated gastrointestinal digestion. The encapsulation efficacy ranged from 41.1 ± 4.7 to 56.7 ± 3.4% with different concentrations of MCE (50-75% v/v), sodium alginate (1.2-1.8% w/v), and CaCl2 solution (3-5% w/v). The optimal condition for MCE-loaded alginate beads (MCB) was composed of 75% MCE, 1.5% alginate, and 3% CaCl2 solution, which provided the highest encapsulation efficiency with a spherical structure and a mean particle diameter of 1516.67 ± 40.96 μm. Fourier transform infrared spectroscopy (FT-IR) reported no chemical interaction between alginate and MCE. The release of total phenolic content (TPC) was only 8.9% after placing MCB in water for 4 h. After simulated digestion, changes in TPC and ferric reducing antioxidant power (FRAP) of MCE significantly decreased by 25.0% and 29.7%, respectively. Interestingly, the incorporation of MCB significantly increased TPC and FRAP in the digesta compared to those of MCE during gastrointestinal tract conditions. The findings suggest that the encapsulation of MCE with alginate as a carrier helps to improve the bioaccessibility and biological activity of M. chinensis polyphenols.

Abstract
Mesona chinensis is an important medicinal and edible plant resource distributed in eight provinces in southern China. In December 2021, an unknown stem and leaf blight disease was found in M. chinensis cultivation areas in Longzhou County, Guangxi, China. Sixty days after transplanting, the incidence of this disease was 10%. Leaf spots mostly appeared from the leaf edge, were irregular, brown to dark brown, causing more than half of the leaf or the whole leaf to die. The infected stem first showed dark brown spots, then constricted slightly, became necrotic and rotted with the expansion of the spots, resulting in the death of the whole plant. Loose cobweb-like mycelia, which resembled Rhizoctonia, could be seen on the diseased tissues in conditions of high humidity. To identify the pathogen, diseased stems and leaves with typical symptoms from Longzhou County were collected and surface-sterilized with 75% ethanol for 30 s. Small fragments (5×5 mm) at the junction of diseased and healthy tissues were disinfected with 1% NaClO for 1min, washed with sterile water three times, transferred to potato dextrose agar (PDA), and incubated at 28°C for 3 days. Mycelial tips were removed, and six isolates (No. R1-R6) were obtained. The colonies were initially gray white and later light brown. Many nearly round to irregular sclerotia appeared after 7 days of culture. The sclerotia turned from light brown to deep brown and were 1 to 5 mm in diameter. The mycelium branched at a 90° angle, with septa near the branches and a constriction of the mycelium at the base of the branch. These morphological characteristics were consistent with Rhizoctonia. For molecular identification, genomic DNA of the six isolates was obtained using an extraction kit (Biocolor, Shanghai, China), and primers ITS4/ITS5 were used to amplify the internal transcribed spacers (ITS) and 5.8S rRNA (White et al. 1990). A 750 bp DNA fragment was obtained and the sequences were deposited in GenBank (OM095383-OM095388). All isolates had ≥ 99% identity with anastomosis group AG1-1B (HG934429 and HQ185364) of R. solani. A phylogenetic tree showed that the isolates and those from anastomosis group AG1-1B clustered into one branch. To satisfy Koch's postulates, the isolates from diseased leaf (No. R1, R2, and R3) and diseased stem (No. R4, R5, and R6) were inoculated on leaves and stems of 45-day-old M. chinensis plants. Five leaves and stems were inoculated with mycelial plugs of each isolate without wounding and another five leaves and stems were inoculated with mycelial plugs of each isolate after pinprick wounding. Control wounded leaves and stems were inoculated with sterile PDA discs. To maintain high humidity, the plants were incubated at 28°C and covered with transparent plastic covers. Diseased spots first appeared 24 h after inoculation. Three days post-inoculation, all inoculated leaves and stems showed symptoms like those observed in the field, whereas controls were asymptomatic. The pathogen was re-isolated from the diseased inoculated tissues using the method described above, and isolated fungi had the morphological characteristics of R. solani. Thus, the pathogen causing stem and leaf blight disease of M. chinensis was determined to be R. solani. The host range of R. solani is wide, and anastomosis group AG1-1B has been reported to infect plants such as rice, bean, fig, cabbage, and lettuce (Sneh et al. 1991). To our knowledge, this is the first report of R. solani causing a stem and leaf blight on M. chinensis, and provides a basis for diagnosis and control of the disease.

Abstract
Chinese mesona (Platostoma palustre) plays an important role as special crop in Southeast Asia and Taiwan for the production of herbal tea, grass jelly, and further processed food. In order to assess the potential threat of fungi to Chinese mesona, we surveyed isolates from symptomless plants in the area of mesona production, as well as from leaf spots of potted plants in a garden shop and a plantation in a botanical garden in Taiwan. From leaves, stems, and roots of 15 symptomless plants sampled at five collection events over two years, 154 isolates from 810 surface-sterilized plant fragments were obtained and identified based on DNA sequence data of the internal transcribed spacer region, and partially of the β-tubulin and histone H3 genes. The most common species belonged to the genera Cercospora, Colletotrichum, and Fusarium and were considered to be potential plant pathogens. Latent pathogenicity was confirmed by an infection experiment with an endophytic strain of Corynespora cassiicola. Observation of leaf spot disease associated with Cercospora kikuchii suggested pathogenicity of this fungus, which was also isolated as an endophyte from symptomless leaves. We hypothesize that the most common endophytic fungi are latent pathogens in the host and may cause plant disease when the host becomes weakened by senescence or changed cultivation condition. Leaf spots of plants in the botanical garden were associated with a species of Pseudocercospora, which was not found among the endophytic isolates and is newly described based on morphology and analysis of translation elongation factor 1 alpha gene sequences.

Abstract
Mesona chinensis is an important traditional Chinese medicine and edible plant resource in China. In this work, we sequenced the complete chloroplast genome of M. chinensis and researched its evolution. The genome size is 152,547 bp, with 37.89% GC content, including a large single copy region (LSC) of 83,482 bp, a small single copy region (SSC) of 17,725 bp and a pair of inverted repeats region (IRs) of 25,670 bp. The complete chloroplast genome was predicted to encode 131 genes, consist of 86 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Phylogenetic analysis showed that M. chinensis was closely related to other Labiatae species Ocimum tenuiflorum.
