Abstract
Amomum tsao-ko is an important spice and medicinal plant that has received extensive attention in recent years for its high content of bioactive constituents with the potential for food additives and drug development. Diarylheptanoids are major and characteristic compounds in A. tsao-ko; however, the biochemical and molecular foundation of diarylheptanoids in fruit is unknown. We performed comparative metabolomics and transcriptomics studies in the ripening stages of A. tsao-ko fruit. The chemical constituents of fruit vary in different harvest periods, and the diarylheptanoids have a trend to decrease or increase with fruit development. GO enrichment analysis revealed that plant hormone signaling pathways including the ethylene-activated signaling pathway, salicylic acid, jasmonic acid, abscisic acid, and response to hydrogen peroxide were associated with fruit ripening. The biosynthetic pathways including phenylpropanoid, flavonoids, and diarylheptanoids biosynthesis were displayed in high enrichment levels in ripening fruit. The molecular networking and phytochemistry investigation of A. tsao-ko fruit has isolated and identified 10 diarylheptanoids including three new compounds. The candidate genes related to diarylheptanoids were obtained by coexpression network analysis and phylogenetic analysis. Two key genes have been verified to biosynthesize linear diarylheptanoids. This integrative approach provides gene regulation and networking associated with the biosynthesis of characteristic diarylheptanoids, which can be used to improve the quality of A. tsao-ko as food and medicine.

Abstract
The fruits of Amomun tsao-ko (Chinese black cardamom; Zingiberaceae) contain an abundance of essential oils, which have previously demonstrated significant antimicrobial activity. In our preliminary search for natural anti-tuberculosis agents, an acetone extract of A. tsao-ko (AAE) exhibited strong antibacterial activity against Mycobacterium tuberculosis H37Rv. Therefore, the aim of this study was to find the principal compounds in an AAE against M. tuberculosis. Nine aliphatic compounds (1−9) including a new compound (1, tsaokol B) and a new natural unsaturated aliphatic diester (6), together with three acyclic terpenoids (10−12), were isolated from an AAE by repetitive chromatography. The structures of the isolates were determined by spectroscopic data analysis. All isolates were evaluated for activity against M. tuberculosis H37Rv. Isolated compounds 1−6, and 11 had MICs ranging from 0.6−89 µg/mL. In contrast, compounds 7 to 10, and 12 had MICs that were >100 µg/mL. Tsaokol A (3) was the most active compound with MICs of 0.6 µg/mL and 1.4 µg/mL, respectively, against replicating and nonreplicating M. tuberculosis. These results are the first to illustrate the potency of tsaokol A (3) as a natural drug candidate with good selectivity for treating tuberculosis.

Abstract
The clinical application of gentamicin may lead to acute kidney injury (AKI), and the nephrotoxicity of gentamicin is related to the pathological mechanism of several oxidative and inflammatory cytokines. Plant-derived essential oils have good anti-inflammatory and antioxidant properties. This study aimed to clarify the protective effect of Amomum tsao-ko essential oils (AOs) on gentamicin-induced AKI in rats and its possible mechanism. The rat AKI model was induced by intraperitoneal injection of gentamicin. After 14 days of oral AO treatment, the renal function and pathological changes of the kidney tissues were evaluated, and the level of kidney tissue oxidative stress was detected. The content of inflammatory cytokines was measured by ELISA. The expression of ERK1/2, JNK1/2, p38, NF-κB, caspase-3, and Bax/Bcl-2 proteins were estimated by Western blot analysis. The results showed that taking AO reduced the contents of serum urea and creatinine in AKI rats and improve the pathological changes and oxidative stress of the kidney tissue in rats. At the same time, AO reduced inflammation and apoptosis during AKI by regulating the MAPK pathway. The data show that AO has a protective effect on the kidneys and may be a potential drug for treating kidney injury.

Abstract
As an important economic and medicinal crop, Amomum tsao-ko is rich in volatile oils and widely used in food additives, essential oils, and traditional Chinese medicine. However, the lack of the genome remains a limiting factor for understanding its medicinal properties at the molecular level. Here, based on 288.72 Gb of PacBio long reads and 105.45 Gb of Illumina paired-end short reads, we assembled a draft genome for A. tsao-ko (2.70 Gb in size, contig N50 of 2.45 Mb). Approximately 90.07% of the predicted genes were annotated in public databases. Based on comparative genomic analysis, genes involved in secondary metabolite biosynthesis, flavonoid metabolism, and terpenoid biosynthesis showed significant expansion. Notably, the DXS, GGPPS, and CYP450 genes, which participate in rate-limiting steps for terpenoid backbone biosynthesis and modification, may form the genetic basis for essential oil formation in A. tsao-ko. The assembled A. tsao-ko draft genome provides a valuable genetic resource for understanding the unique features of this plant and for further evolutionary and agronomic studies of Zingiberaceae species.

Abstract
The effects of twelve different pre-drying and drying methods on the chemical composition in the pericarp and kernel of Amomum tsao-ko were studied. The volatile components were isolated from the samples by simultaneous distillation and extraction and analyzed by gas chromatography-mass spectrometry (GC-MS). Sixty and thirty-eight compounds were identified from pericarp and kernel, respectively, and the main constituents were oxygenated monoterpenes. These compounds were not only significantly affected by pre-drying and drying methods but also varied in content due to different tissue locations. The total volatile content of pericarp varied from 0.70 to 1.55%, with the highest obtained by microwave-dried samples (150 W) and the lowest in freeze-dried samples. The total volatile content of the kernel varied from 6.11 to 10.69%, with the highest content obtained during sun drying (SD) and the lowest content in samples treated with boiling water for 2 min. Oxygenated monoterpenes were the highest compounds in pericarp and kernel, which were also the most affected by drying methods. The highest content of oxygenated monoterpenes in the pericarp (0.77%) could be obtained by boiling water treatment for 5 min, and the highest content of oxygenated monoterpenes in the kernel (7.48%) could be obtained by SD. Additionally, the main components such as 1,8-cineole, 2-carene, (Z)-citral, nerolidol, (Z)-2-decenal, (E)-2-dodecenal, citral, (E)-2-octenal, 4-propylbenzaldehyde, and phthalan showed remarkable variations in pre-drying and drying methods.

Abstract
In recent years, the pathogen that causes leaf blast on Amomum tsao-ko repeatedly infected the plants in a large area of Luchun County, Honghe Prefecture, Yunnan Province, China. The disease is caused by the pathogen Pyricularia variabilis. The effects of light, temperature, pH, carbon, and nitrogen sources on the growth of the pathogen were determined, and its sensitivity to six fungicides was determined using the mycelial growth rate method. The optimal conditions for mycelial growth were as follows: temperature: 20–25°C; carbon source: maltose, nitrogen source beef extract, media corn flour, and potato dextrose agar. The mycelia could grow under four types of light conditions: 24 h light, 24 h dark, 12 h light/12 h dark, and 16 h light/8 h dark. In addition, Propiconazole was the most effective inhibitor, with an EC50 value of 0.030 μg/mL, and prochloraz was the second most effective, with an EC50 value of 0.076 μg/mL. It is suggested that the two fungicides should be alternated when used in production. Carbendazim and chlorothalonil were ineffective in inhibiting the fungus, with EC50 values of 6.137 and 3.765 μg/mL, respectively.

Abstract
Due to the world-wide concern relating to herb quality and safety, there is a momentum to authenticate the geographical origin of herb with multi-platform techniques. This study attempted to assess multi-platform information as a practical strategy for the geographical traceability of the fruits of Amomum tsao-ko. To this aim, one hundred and eighty dried fruits of A. tsao-ko from five geographical regions were analyzed by near infrared (NIR) and ultraviolet visible (UV-Vis) spectroscopy. On this basis, two variable dimension reduction strategies, including principal component analysis (PCA) and sequential and orthogonalized partial-least squares (SO-PLS), and two variables selection strategies, including variable importance in projection (VIP) and sequential and orthogonalized covariance selection (SO-CovSel), were performed to extract the feature information in the two blocks. Partial least squares discriminant analysis (PLS-DA) classification algorithm combined with fused matrices was used to identify the geographical origins. The results of PLS-DA models indicated that SO-PLS and SO-CovSel, taking advantage of the sequential modeling coupled to orthogonalization, could not only identify the common information presented in the two blocks but also provide more concise methods without any loss of classification ability, which could be employed in authenticating the geographical regions of the fruits of A. tsao-ko, effectively.

Abstract
Amomum tsao-ko Crevost & Lemarié is an important crop that has been widely used in traditional Chinese medicine and daily diets for a long time. In this study, the genetic diversity and relationships of eight cultivated populations of A. tsao-ko grown in Southwest China were examined using sequence-related amplified polymorphism (SRAP) and inter-simple sequence repeat (ISSR) markers. The results showed that 139 (99.29%) of 140 and 185 (99.46%) of 186 bands were polymorphic by SRAP and ISSR primers amplification, respectively. The polymorphic information content of detected bands were 0.270 (SRAP) and 0.232 (ISSR), respectively. The average Nei's gene diversity (H = 0.217) and Shannon's information index (I = 0.348) at the species level generated by SRAP primer were higher than those by ISSR analysis (H = 0.158, I = 0.272). Genetic differentiation coefficients and molecular variance analysis (AMOVA) indicated that the genetic variance of A. tsao-ko mainly occurred within populations rather than among populations. The high genetic identity among populations was revealed by SRAP (0.937) and ISSR (0.963). Using UPGMA cluster analysis, principal coordinate analysis, and population structure analysis, the accessions were categorized into two major groups. Overall, results obtained here will be useful for A. tsao-ko germplasm characterization, conservation, and utilization.

Abstract
Amomum tsao-ko Crevost et Lemaire (Zingiberaceae) is a medicinal herb found in Southeast Asia that is used for the treatment of malaria, abdominal pain, dyspepsia, etc. The aim of this study was to investigate the effect of an ethanol extract of Amomum tsao-ko (EAT) on obesity and hyperlipidemia in C57BL/6 mice fed a high-carbohydrate diet (HCD). First, the mice were divided into five groups (n = 6/group) as follows: normal diet, HCD, and HCD+EAT (100, 200, and 400 mg/kg/day), which were orally administered with EAT daily for 84 days. Using microcomputed tomography (micro-CT) analysis, we found that EAT inhibited not only body-weight gain, but also visceral fat and subcutaneous fat accumulation. Histological analysis confirmed that EAT decreased the size of fat tissues. EAT consistently improved various indices, including plasma levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein, high-density lipoprotein, atherogenic index, and cardiac risk factors, which are related to dyslipidemia—a major risk factor for heart disease. The contents of TC and TG, as well as the lipid droplets of HCD-induced hepatic accumulation in the liver tissue, were suppressed by EAT. Taken together, these findings suggest the possibility of developing EAT as a therapeutic agent for improving HCD-induced obesity and hyperlipidemia.

Abstract
In Asia, Amomum tsao-ko has long been used as a spice or seasoning in food to stimulate digestion. In the present study, we evaluated the effects of ethanol extract of Amomum tsao-ko (EEAT) on menopausal osteoporosis and obesity. After the administration of EEAT in ovariectomy (OVX) mice models for five weeks, microcomputed tomography and a histological analysis were performed to assess, respectively, the trabecular structure and the fat accumulation in adipose, liver, and bone tissues. We also examined the effects of EEAT on a bone marrow macrophage model of osteoclastogenesis by in vitro stimulation from the receptor activator of nuclear factor-kappa Β ligand (RANKL) through real-time PCR and Western blot analysis. In addition, ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) with authentic standards was applied to characterize the phytochemical profiling of EEAT. We found that EEAT significantly decreased OVX-induced body weight gain and fat accumulation, significantly prevented OVX-induced deterioration of bone mineral density and microstructure of trabecular tissues, and significantly inhibited osteoclast differentiation by downregulating NF-κB/Fos/NFATc1 signaling in osteoclasts. Furthermore, UHPLC-MS/MS identified eight beneficial phytochemicals in EEAT. Collectively, these results suggest that EEAT might be an effective nutraceutical candidate to attenuate menopausal osteoporosis by inhibiting osteoclastogenesis and to prevent obesity by suppressing fat accumulation.

Abstract
In our search for novel plant-derived inhibitors of nitric oxide (NO) with potential for treating inflammatory diseases, the phytochemicals of Amomum tsao-ko fruits were investigated, leading to the isolation of one bicyclic nonane (1), three menthene skeleton monoterpenoids (2-4), and two acyclic monoterpenoids (5 and 6). Their structures were identified using one- and two-dimensional nuclear magnetic resonance spectroscopy, and mass spectrometry. To the best of our knowledge, compounds 2-5 were obtained from the genus Amomum for the first time. All isolates were tested for their ability to inhibit lipopolysaccharide-stimulated NO overproduction in RAW264.7 cells. Compound 4 was found to inhibit NO production. Western blotting analysis indicated that active compound 4 can regulate inducible NO synthase expression. In addition, lipopolysaccharide-induced interleukin 1 beta and interleukin-6 overproduction was reduced in a concentration-dependent manner.

Abstract
Amomum tsao-ko (Zingiberaceae) is a traditional Chinese medicine and condiment, and an important economic crop in the tropical forest of southwest China. However, few simple sequence repeat (SSR) markers are available in A. tsao-ko, which is hindering genetic research in this species. The aim of this study was to develop and characterize microsatellite markers for A. tsao-ko using restriction-site-associated DNA sequencing. A total of 115,482 microsatellites were identified using MISA software, and 13,411 SSR primer pairs were designed. 100 pairs of SSR primers were selected at random and used to evaluate polymorphisms among 4 A. tsao-ko samples. Finally, 23 pairs of SSR primers with clear bands and obvious polymorphism were selected for genetic diversity analysis of 72 A. tsao-ko accessions. The number of alleles and effective number of alleles per locus ranged from 2 to 6 and from 1.315 to 3.776, respectively. The observed heterozygosity ranged from 0.208 to 0.779, and the expected heterozygosity was from 0.239 to 0.735. The average values of the polymorphic information content were 0.454. Hardy–Weinberg equilibrium (HWE) analysis showed that 10 loci significantly deviated from HWE (P < 0.05). The pairwise FST and genetic distance values revealed low levels of genetic differentiation and high genetic similarity among six A. tsao-ko populations. These microsatellite markers developed will provide a valuable tool for further germplasm characterization, genetic diversity, and breeding studies in A. tsao-ko.

Abstract
The dried fruits of Amomum tsao-ko were first revealed to have hypoglycemic effects on db/db mice at a concentration of 200 mg/kg. In order to clarify the antidiabetic constituents, 19 new flavanol-fatty alcohol hybrids, tsaokoflavanols A-S (1-19), were isolated and determined by extensive spectroscopic data and ECD calculations. Most of the compounds showed α-glucosidase and PTP1B dual inhibition, among which 1, 2, 6, 11, and 18 exhibited obvious activity against α-glucosidase with IC50 values of 5.2-9.0 μM, 20-35 times stronger than that of acarbose (IC50, 180.0 μM); meanwhile, 6, 10-12, and 19 were PTP1B/TCPTP-selective inhibitors with IC50 values of 56.4-80.4 μM, 2-4 times stronger than that of suramin sodium (IC50, 200.5 μM). Enzyme kinetics study indicated that compounds 1, 2, 6, and 11 were α-glucosidase and PTP1B mixed-type inhibitors with Ki values of 13.0, 11.7, 2.9, and 5.3 μM and 142.3, 88.9, 39.2, and 40.8 μM, respectively. Docking simulations proved the importance of hemiacetal hydroxy, the orientation of 3,4-dihydroxyphenyl, and the length of alkyl in binding with α-glucosidase and PTP1B.

Abstract
Eleven undescribed diarylheptanoids, amomutsaokols A‒K (1-11), together with 13 known ones (13-24), were isolated from the active fraction of the fruits of Amomum tsao-ko. The structures of the undescribed compounds were determined by extensive 1D and 2D NMR, HRESIMS and ECD calculations. Compounds 3-5, 7, 8, 12, 14 and 19 showed obviously α-glucosidase inhibitory activity with IC50 values ranging from 12.9 to 48.8 μM. An enzyme kinetic analysis indicated that compounds 8 and 9 were α-glucosidase noncompetitive inhibitors with Ki values of 18.5 and 213.0 μM, respectively. This study supported diarylheptanoids as the active constituents of A. tsao-ko with α-glucosidase inhibitory effects.

Abstract
Amomum tsao-ko (Zingiberaceae) is an important edible and medicinal crop. The complete chloroplast (cp) genome of A. tsao-ko was determined using Illumina sequencing platform. The size of whole cp genome was 163,648 bp, containing a small single copy (SSC) region of 15,355 bp and a large single copy (LSC) region of 88,741 bp, which were separated by a pair of inverted repeat (IRs) regions (29,776 bp). The A. tsao-ko cp genome contained 133 genes, including eight ribosomal RNA genes (4 rRNA species), 38 transfer RNA genes (30 tRNA species) and 87 protein-coding genes (79 PCG species). The overall GC content of A. tsao-ko cp genome is 36.02%. To investigate the evolution status of A. tsao-ko, as well as Zingiberales, a phylogenetic tree with A. tsao-ko and other 16 species was constructed based on their complete chloroplast genomes. Phylogenetic analysis revealed that A. tsao-ko was closely related to Alpinia zerumbet.

Abstract
Amomum tsao-ko Crevost et Lemarié (Zingiberaceae) has traditionally been used to treat inflammatory and infectious diseases, such as throat infections, malaria, abdominal pain and diarrhoea. This study was designed to assess the anti-inflammatory effects and the molecular mechanisms of the methanol extract of A. tsao-ko (AOM) in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages and in a murine model of sepsis. In LPS-induced RAW 264.7 macrophages, AOM reduced the production of nitric oxide (NO) by inhibiting inducible nitric oxide synthase (iNOS) expression, and increased heme oxygenase-1 (HO-1) expression at the protein and mRNA levels. Pretreatment with SnPP (a selective inhibitor of HO-1) and silencing HO-1 using siRNA prevented the AOM-mediated inhibition of NO production and iNOS expression. Furthermore, AOM increased the expression and nuclear accumulation of NF-E2-related factor 2 (Nrf2), which enhanced Nrf2 binding to antioxidant response element (ARE). In addition, AOM induced the phosphorylation of extracellular regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) and generated reactive oxygen species (ROS). Furthermore, pretreatment with N-acetyl-l-cysteine (NAC; a ROS scavenger) diminished the AOM-induced phosphorylation of ERK and JNK and AOM-induced HO-1 expression, suggesting that ERK and JNK are downstream mediators of ROS during the AOM-induced signalling of HO-1 expression. In LPS-induced endotoxaemic mice, pretreatment with AOM reduced NO serum levels and liver iNOS expression and increased HO-1 expression and survival rates. These results indicate that AOM strongly inhibits LPS-induced NO production by activating the ROS/MAPKs/Nrf2-mediated HO-1 signalling pathway, and supports its pharmacological effects on inflammatory diseases.

Abstract
Amomum tsao-ko Crevost et Lemaire, used as a spice in Asia, is an important source of Chinese cuisine and traditional Chinese medicines. A. tsao-ko is reported to exert a variety of biological and pharmacological activities, including anti-proliferative, anti-oxidative and neuroprotective effects. In this study, NNMBS227, consisting of the ethanol extract of A. tsao-ko, exhibited potent anti-inflammatory activities in RAW264.7 macrophages. We investigated the effect of NNMBS227 in the suppression of pro-inflammatory mediators, including pro-inflammatory enzymes (inducible nitric oxide synthase and cyclooxygenase-2) and cytokines (tumor necrosis factor-α and interleukin-1β) in LPS stimulated macrophages. NNMBS227 also inhibited the phosphorylation and degradation of IκB-α, as well as the nuclear translocation of nuclear factor kappa B (NF-κB) p65 caused by stimulation with LPS. In addition, NNMBS227 induced heme oxygenase (HO)-1 expression through the nuclear translocation of nuclear factor E2-related factor 2 (Nrf2) in macrophages. Using tin protoporphyrin (SnPP), an HO activity inhibitor, we confirmed an association between the anti-inflammatory effects of NNMBS227 and the up-regulation of HO-1. These findings suggest that Nrf2-dependent increases in the expression of HO-1 induced by NNMBS227 conferred anti-inflammatory activities in LPS stimulated RAW264.7 macrophages.
