Abstract
Edible plant-derived exosome-like nanoparticles (PELNs) provide numerous benefits, including high yield, low cost, ethical compatibility, and multiple health benefits, which enable them to address technical constraints associated with mammalian nanoparticles. Herbs, known for their abundant bioactive components, are considered the primary source of natural medicines within the plant kingdom. Recently, a number of herbaceous sources have been investigated for the isolation and functionality of exosome-like nanoparticles (ELNs). However, they are commonly referred to as PELNs, and their distinct pharmacological properties are overlooked. In this review, these herb-derived ELNs are designated as HELNs, a novel herbal product that may also exhibit superior pharmacological activity compared to other types of PELNs. Among the documented HELNs, ginger-derived exosome-like nanoparticles (GELNs) are the most extensively studied. This review employs GELNs as an exemplar to delineate the process of extraction and purification, together with their physical and biochemical characteristics and therapeutic potential. The aim of this review is to promote the development and application of HELNs, and future research is encouraged to uncover their additional properties, extending beyond those of GELNs.

Otho AA, Memon RA, Abro SA, Memon AA. Elemental Analysis of Medicinal Herb Fagonia indica Burm. f. and Its Rhizospheric Soil from Six Geographical Locations of South-eastern Sindh Province, Pakistan, During Spring and Summer Seasons. Biol Trace Elem Res 2022; 200:2439-2454.

Abstract
This study hypothesized that seasons and geography may affect the elemental composition of Fagonia indica. The plant was sampled along with rhizospheric soil, from six hilly geographical sites of Sindh, during March (Spring) and July (Summer) and analyzed through ICP-OES. Among 20 elements detected, the elemental concentration of rhizospheric soil was significantly affected by geography rather than seasons. The rhizospheric soil elements, Fe, Mg, Hg, K, Mn, Na, Zn, Al, were hyper-concentrated, B, Ba, Cr, Cu, Pb, Sr were moderately concentrated, and As, Cd, Ni, Rb, Ti, V were concentrated in trace levels. Contrarily, elements in Fagonia indica biomass were significantly affected by both seasons and geography. K, Na, Fe, Hg, Al, Mn, Sr, Cr, Ti, V were hyperaccumulated during summer, while Mg, Zn, As, Ba, Cd, and Cu accumulated higher during spring. PCA reveals that elements with high variances were homogenously distributed to all sites except Rohri during spring, while during summer most elements were accumulated at Johi, Dadu, Jamshoro, and Karachi. In conclusion, the plant accumulates high concentration of heavy metals during summer and higher concentration of essential nutrients during spring; therefore, its collection for oral use can be recommended during spring.

Abstract
The aim of this work has been to establish and validate a simple and efficient method to detect the concentration of inulin-type fructan CPA from the roots of Codonopsis pilosula (Franch.) Nannf. in biosamples, and then apply it to evaluate the pharmacokinetics behavior, distribution character in tissue and excretion in mice. In this work, fluorescein isothiocyanate (FITC) was used to label CPA. Then FCPA was intravenously and orally administered to mice at different doses. In both i.v and p.o administration, FCPA concentration slowly declined in the circulatory system with a much longer T1/2 and MRT. After p.o administration, the area under the time curve (AUC0-∞) was dose-dependently increased. Taken together, FCPA showed poor absorption and wide tissue distribution. These pharmacokinetic results yield helpful insights into the pharmacological actions of FCPA.

Abstract
Abstract
Saline–alkali stress is a major abiotic stress affecting the quality and yield of crops. Astragalus membranaceus (Fisch) Bge. var. mongholicus (Bge.) Hsiao (A. mongholicus) is a well-known medicine food homology species with various pharmacological effects and health benefits that can grow well in saline–alkali soil. However, the molecular mechanisms underlying the adaptation of A. mongholicus plants to saline–alkali stress have not yet been clarified. Here, A. mongholicus plants were exposed to long-term saline–alkali stress (200 mmol·L -1 mixed saline–alkali solution), which limited the growth of A. mongholicus. The roots of A. mongholicus could resist long-term saline–alkali stress by increasing the activity of antioxidant enzymes and the content of osmolytes. Transcriptome analysis (via the Illumina platform) and metabolome analysis (via the Nexera UPLC Series QE Liquid Mass Coupling System) revealed that saline–alkali stress altered the activity of various metabolic pathways (e.g., amino acid metabolism, carbohydrate metabolism, lipid metabolism, and biosynthesis of other secondary metabolites). A total of 3,690 differentially expressed genes (DEGs) and 997 differentially accumulated metabolites (DAMs) were identified in A. mongholicus roots under saline–alkali stress, and flavonoid-related DEGs and DAMs were significantly up-regulated. Pearson correlation analysis revealed significant correlations between DEGs and DAMs related to flavonoid metabolism. MYB transcription factors might also contribute to the regulation of flavonoid biosynthesis. Overall, the results indicate that A. mongholicus plants adapt to saline–alkali stress by up-regulating the biosynthesis of flavonoids, which enhances the medicinal value of A. mongholicus.

Abstract
BACKGROUND Astragali Radix (AR) is widely used because of its dual use in medicine and food. Wild Astragali Radix from Hunyuan county of Shanxi Province in China is accepted as a geo-authentic medicine with high quality and good medicinal effects. Multi-elements of Astragali Radix partially reflect its efficacy and safety. However, there is no systemic research about the elemental analysis of geo-authentic Astragali Radix until now. OBJECTIVE In this paper, multi-elemental profiling of Astragali Radix from Gansu, Jilin, Inner Mongolia, Shaanxi and Shanxi provinces in China was implemented. METHODS A microwave digestion coupled with ICP-MS, principle component analysis and partial-least square-discriminate analysis were used for the analysis of unique elemental accumulation ability of Shanxi wild-type. RESULTS For 53 stably detected elements, the contents of most elements (Ba, Cs, Ga, La, Pr and so on) were significantly higher while some others (Cd, Cu, P, W and Zn) were significantly lower in wild Astragali Radix from Shanxi than those of the samples from Gansu, Jilin, Inner Mongolia, Shaanxi provinces and the cultivated samples from Shanxi. After binary logistic regression, combinational variable Ba-P was found to be a good marker to identify wild Astragali Radix of Shanxi Province from the samples with other origins, and the total positive prediction probability of the test samples from both market and their original field could reach 93.8% through external validation using the model. CONCLUSIONS Multi-elemental analysis coupled with PCA, PLS-DA, nonparametric analysis and binary logistic regression can be a good tool for the identification of wild Astragali Radix from Shanxi Province. HIGHLIGHTS An ICP-MS method was developed and validated for multi-elements. Fifty-three elements in Astragali Radix from differential origins were compared. The wild Astragali Radix from Shanxi had unique elemental characteristics. Combinational variable Ba-P is a good marker to identify wild-type from Shanxi.

Abstract
Carborane are widely applied in boron neutron capture therapy (BNCT) field, but it is difficult to perform biocompatibility with cells due to its own water solubility differences, so how to solve the water solubility problem has always been the focus of research. A simple, inexpensive and effective method was used to study the synthesis of nido-carborane azaspirodecanium poly(carboxybetaine methacrylate) by one-pot cyclization of nido-carborane azaspirodecanium under the synergistic effect of inorganic bases and conventional organic solvents. Its characterization is mainly to use 1H-NMR nuclear magnetic resonance spectrum and infrared spectroscopy to determine the characteristic peak and range of borane. Through transmission electron microscope (TEM), it can be observed that the white nanoparticles, namely carborane, are completely contained by polymer ions, which not only increases the surface area but also the concentration of boron uptake in the cell is 100 times that of borono-phenylalanine (BPA). Based on the successful synthesis of N-CB5-4 and N-CB6-5 without harsh conditions, a feasibility point of view was put forward, namely, super water-soluble carborane polymer.

Abstract
Astragalus membranaceus is an important traditional Chinese herb whose roots have been used for medicinal purposes for more than 2000 years. Because of excessive exploitation, the wild resources are currently almost exhausted, and therefore, artificial planting of Astragalus membranaceus has been increasingly important. But to date, few studies have focused on the active ingredients and mineral element of Astragalus membranaceus in the Qinghai-Tibet Plateau.In this study, five density gradients (M1: 10 cm × 25 cm, M2: 15 cm × 25 cm, M3: 20 cm × 25 cm, M4: 25 cm × 25 cm and M5: 30 cm × 25 cm) were assessed to evaluate the effects of various planting densities on the mineral element and secondary metabolite content of Astragalus membranaceus roots in different months. It was found that the content of calycosin-7-O-β-D-glucoside and astragaloside IV reached its highest in October. Ononin content increased month by month, while formononetin content decreased during months. Calycosin content did not show significant changes during seasons. Taken together, these results suggest that the optimal planting density is 15 cm × 25 cm (D2) and the optimal harvest period is October. According to the results, the Cu content in all samples did not exceed the limit (20 mg/kg). Principal component analysis (PCA) revealed that Na, P, K Al, Ba, Ca, Fe, Li, and Mn were selected as characteristic elements of Astragalus membranaceus. The results also showed a high correlation between elements and active ingredients. Ba and Co had extremely significant associations with astragaloside IV.

Abstract
Objective Astragalus membranaceus root is a well-known traditional Chinese herbal medicine with many biological active constituents. This study was conducted to examine the effects of Astragalus membranaceus root powder (AMP) on growth performance, serum antioxidant and immune response in finishing lambs. Methods A total of thirty-six Guangling fat-tailed ram lambs (body weight = 19±2 kg, mean ±standard deviation) were randomly assigned to one of six treatments for a 40 d feeding period, with the first 10 d for adaptation. Treatments consisted of the lambs’ basal diets with addition of 0, 5, 10, 15, 20, and 30 g/kg of diet of AMP. Results Response to supplementation level of AMP was quadratic (p≤0.032) for final weight and ADG with the greatest at 10 g/kg of diet, but dry matter intake was not affected (p≥ 0.227) by treatments. The increase of AMP supplementation resulted in a quadratic response in contents of triglyceride and creatinine (p<0.05), with the lowest values for 10 and 20 g/kg of diet, respectively. A linear and quadratic decrease was observed in activity of alkaline phosphatase in serum of lambs. As the AMP supplementation increased, the activities of total superoxide dismutase and total antioxidant capacity increased linearly (p≤0.018) and hydroxyl radical (OH−) decreased linearly (p = 0.002). For catalase (CAT) and malondialdehyde (MDA), quadratic (p≤0.001) effects were observed among treatments, with the greatest CAT and lowest MDA values at 10 g/kg AMP. Additionally, supplementing AMP up to a level of 10 or 15 g/kg of diet quadratically increased immunoglobulin and interleukin contents in the serum. Conclusion The results indicated that AMP can be used as natural feed additive in the ration of lambs to improve ADG, antioxidant status, and immune functions, and the optimal dose was 10 g/kg of diet under the condition of this experiment.

Abstract
Astragalus mongholicus Bunge (Fabaceae) is an important plant source of the herbal drug known as Radix Astragali, which is used worldwide as a medicinal ingredient and a component of food supplement. Russian Federation, Mongolia, Kazakhstan, and China are the main natural distribution areas of A. mongholicus in the world. However, the quality of medicinal plant varies among different locations. As for A. mongholicus, limited literature focused on its biodiversity mechanism. Here, we combined the chemometric analysis of chemical components with genetic variation, as well as climatic and edaphic traits, to reveal the biodiversity mechanism of A. mongholicus. Results showed that the detected chemical, genetic and climatic traits comprehensively contributed to the quality diversity of A. mongholicus. The eight main chemical components, as well as the inorganic elements of P, B and Na were all significant chemical factors. The precipitation and sunshine duration were the main distinguishing climatic factors. The inorganic elements As, Mn, P, Se and Pb were the distinguishing edaphic factors. The systematic method was firstly established for this medicinal plant in order to illustrate the formation of diversity in terms of quality, and provide scientific evidence for geographic indications and climatic adaptation in production and in the clinical application of herbal medicinal plants.
