Qin Y, Liu W, Zhang X, Adamowski JF, Biswas A. Leaf Stoichiometry of Potentilla fruticosa Across Elevations in China's Qilian Mountains. FRONTIERS IN PLANT SCIENCE 2022; 13:814059. [PMID: 35283932 PMCID: PMC8907977 DOI: 10.3389/fpls.2022.814059] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Accepted: 01/10/2022] [Indexed: 05/21/2023]
Abstract
As an individual plant species can develop its own leaf stoichiometry to adapt to environmental changes, this stoichiometry can provide critical information about a plant species' growth and its potential management in the ecosystem housing it. However, leaf stoichiometry is largely undocumented in regions with large environmental changes arising from differences in elevation. The leaf stoichiometry of Potentilla fruticosa L., a major alpine shrub playing an important role in supporting ecosystem functions and services in China's Qilian Mountains (Northeast Qinghai-Tibetan Plateau), was investigated at different elevations (2,400, 2,600, 2,800, 3,000, 3,200, 3,500, and 3,800 m). At each elevation, leaf elemental (C, N, and P) concentrations were measured in P. fruticosa leaves sampled from three plots (10 × 10 m), and edaphic properties were assessed in nine quadrats (1 × 1 m, three quadrats per plot). Temperature and precipitation were calculated using an empirical formula. Maximum and minimum leaf carbon (C) concentrations ([C] leaf ) of 524 ± 5.88 and 403 ± 3.01 g kg-1 were measured at 2,600 and 3,500 m, respectively. Leaf nitrogen (N) concentration ([N] leaf ) showed a generally increasing trend with elevation and peaked at 3,500 m (27.33 ± 0.26 g kg-1). Leaf phosphorus (P) concentration ([P] leaf ) varied slightly from 2,400 to 3,200 m and then dropped to a minimum (0.60 ± 0.10 g kg-1) at 3800 m. The [C] leaf :[N] leaf , [C] leaf :[P] leaf , and [N] leaf :[P] leaf varied little from 2,400 to 3,000 m but fluctuated somewhat at higher elevations. The main factors affecting P. fruticosa leaf stoichiometry were soil organic C, pH, and soil total P, and the main limiting element for the growth of P. fruticosa in the study area was P. In conclusion, changes in elevation affected leaf stoichiometry of P. fruticosa mainly due to altered soil properties, and addressing phosphorus limitation, especially at higher elevations mainly due to losses caused by high precipitation and sparse vegetation, is a key measure to promote P. fruticosa growth in this region.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Potentilla plants are still common herbal medicines used in folk medicine. This review provides an update of research undertaken on Potentilla from 2009 until 2020. AIM OF THE STUDY This comprehensive review considers biological updates, recent advances in phytochemical and pharmacological research, and toxicological reports on Potentilla sensu lato based on available data since 2009. METHODS A literature search was conducted using available databases including ScienceDirect, PubMed, Scopus, Web of Science, China National Knowledge Infrastructure and Google Scholar. RESULTS Until now, more than 210 new and known compounds, including flavonoids, tannins, triterpenes and phenolic compounds, have been confirmed and elucidated for numerous Potentilla species, i.e., in the underground and aerial parts of this genus. Modern pharmacology studies have revealed that those structures are responsible for a broad spectrum of pharmacological activities, such as anti-neoplastic, antihyperglycemic, anti-inflammatory, antioxidant, hepatoprotective, neuroprotective, antibacterial and anti-yeast effects. CONCLUSIONS However, in vitro studies must be re-considered due to the discovery of urolithins and their origins, including microbiota, which can lead to different results when applying Potentilla species and their extracts to in vivo conditions. Thus, future research should focus more on in vivo and particularly clinical studies to confirm the validity and safety of traditional uses. Particularly, the use of Potentilla alba extracts in the treatment of thyroid gland disorders should be further explored to confirm the underlying mechanism of their action, efficacy and safety. In addition, more clinical studies should focus on Potentilla erecta rhizome extracts for application as herbal remedies against dysentery, diarrhoea and inflammation of the skin.

High-Pressure Extraction of Antioxidant-Rich Fractions from Shrubby Cinquefoil ( Dasiphora fruticosa L. Rydb.) Leaves: Process Optimization and Extract Characterization. Antioxidants (Basel) 2020; 9:antiox9060457. [PMID: 32466350 PMCID: PMC7346160 DOI: 10.3390/antiox9060457] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 05/18/2020] [Accepted: 05/21/2020] [Indexed: 01/06/2023] Open
Abstract
Dasiphora fruticosa (basionym Potentilla fruticosa) is a shrub, known in traditional medicine for centuries. Due to the wide range of pharmacological effects, interest and applications of D. fruticosa extracts are continually increasing; however, reports on optimization of extraction conditions are scarce. Herein, a multi-step high-pressure extraction process with increasing polarity solvents was developed to isolate valuable fractions from D. fruticosa leaves. Supercritical CO2 extraction recovered 2.46 g/100 g of lipophilic fraction, rich in polyunsaturated fatty acids. Further, pressurized liquid extractions (PLE) with acetone, ethanol, and water were applied to obtain antioxidant-rich higher polarity extracts. Under optimized PLE conditions, the cumulative polar fraction yield was 29.98 g/100 g. Ethanol fraction showed the highest yield (15.3 g/100 g), TPC values (148.4 mg GAE/g), ABTS•+, and DPPH• scavenging capacity (161.1 and 151.8 mg TE/g, respectively). PLE was more efficient than conventional solid–liquid extraction in terms of extraction time, extract yields, and in vitro antioxidant capacity. Phytochemical characterization of PLE extracts by UPLC-Q-TOF-MS revealed the presence of hyperoside, ellagic acid, among other health beneficial phenolic substances. Τhis study highlights the potential of high-pressure extraction techniques to isolate antioxidant-rich fractions from D. fruticosa leaves with multipurpose applications, including the prevention and treatment of chronic diseases.

Abstract
Heart failure (HF) is an end-stage of various serious cardiovascular diseases, which causes liver injury. Hyperoside has been reported to exert protective effect on liver injury and fibrosis. However, the role and related mechanisms of hyperoside in HF-induced liver fibrosis are still unclear. In the current study, we established a model of HF via aortocaval fistula (ACF) in rats in vivo. Hyperoside treatment in ACF rats increased cardiac output, the maximum peak rate of rise/fall in left ventricular pressure (+dP/dt, -dP/dt) and LV ejection fraction (LVEF), decreased LV end-systolic pressure (LVESP), LV end-diastolic pressure (LVEDP) and LV end-systolic volume (LVESV), and reduced heart weight/body weight ratio in a dose-dependent manner. Moreover, hyperoside could attenuate liver fibrosis and injury in ACF rats, as evidenced by reduction of fibrosis area and hydroxyproline content, amelioration of edema and degeneration of liver cell vacuoles, and inhibition of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) levels. Further, α-smooth-muscle actin (α-SMA), collagen I, profibrotic factor-connective tissue growth factor (CTGF), matrix metalloproteinase-2 (MMP2) and MMP9 levels were down-regulated in hyperoside-treated ACF rats. Additionally, hyperoside inhibited the activation of TGF-β1/Smad pathway. Finally, we confirmed that hyperoside suppressed TGF-β1-mediated hepatic stellate cell activation in vitro. Collectively, hyperoside showed a suppressive role in HF-induced liver fibrosis and injury.

Abstract
In this study, we investigated the antimicrobial, antioxidant, and cytoprotective activities of ethanol extract and the ethyl acetate (EtOAc) fraction of P. kleiniana Wight & Arn. The EtOAc fraction exhibited antimicrobial effects against most of the microorganisms that were tested, including Staphylococcus aureus, Candida albicans, Pseudomonas aeruginosa, and, Escherichia coli, but not Aspergillus niger. In addition to its excellent antioxidant activity, the EtOAc fraction attenuated the UVB-induced cell death via upregulation of caspase-3 expression in human keratinocytes. The HPLC/ESI-MS/MS analysis allowed identification of the components in the EtOAc fraction. Overall, our results suggest that P. kleiniana is a valuable source of bioactive compounds for the development of pharmaceuticals and cosmetics.

Abstract
Eucommia ulmoides Oliv. is widely regarded in China as a precious medicinal and commercial endemic tree. Due to cross-breeding or natural variation of E. ulmoides, the metabolite composition may vary significantly, making control of the medical quality difficult. In order to improve the rational development and utilization, the quality of seven varieties of E. ulmoides were evaluated based on metabolite profiles (total phenolic, total flavonoid, gutta-percha, aucubin, geniposidic acid, chlorogenic acid, geniposide, pinoresinol diglucoside, rutin, hyperoside, and astragalin), bioactivities (in vitro, in vivo antioxidant activities, and antibacterial activities) and HPLC fingerprint combined with chemometrics analysis. On this basis, the differences of medicinal parts (leaf and bark) were further carried out. For the traditional use of bark, Purple-leaf E. ulmoides was the most suitable. For the use of leaf, Qinzhong 1 and Purple-leaf E. ulmoides were appropriate. HPLC fingerprint analysis showed that significant differences in metabolite profiles exist among seven varieties of E. ulmoides. Combined with chemometrics analysis, seven varieties of E. ulmoides were divided into three groups from the use of leaf and bark. The analysis not only evaluated quality of seven varieties of E. ulmoides, but also could distinguish different varieties and different regions of origin. The results can provide theoretical basis for E. ulmoides resources utilization and cultivation of fine varieties.
