Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pfaffia glomerata (Spreng.) Pedersen, Amaranthaceae, is found in South America, mainly in Brazil, where it is considered a species of great medicinal interest owing to its popular use as a tonic, aphrodisiac, anti-inflammatory, and analgesic. These properties can be attributed to the presence of the phytosteroid, 20-Hydroxyecdysone (β-ecdysone), the main compound found in its roots. AIM OF THE REVIEW This review aims to provide information about the botanical characteristics, ethnomedicinal uses, the phytochemistry, the biological activities, and the biotechnology of P. glomerata, an important species to local communities and groups researching medicinal plants of South America. MATERIALS AND METHODS The information available on P. glomerata was collected from scientific databases (ScienceDirect, PubMed/MEDLINE, SciELO, and Scopus) until June 7, 2023, using the search terms "Pfaffia glomerata", "Pfaffia glomerata (Spreng.) Pedersen", and "Brazilian ginseng". The review includes studies that evaluated the botanical, ethnopharmacological, and phytochemical aspects, biological properties, nutraceutical uses, and the application of biotechnology for improving the biosynthesis of metabolites of interest. RESULTS A total of 207 studies were identified, with 81 articles read in full. Seventy-six studies were included for qualitative synthesis. Overall, 40 compounds belonging to different classes are presented in this review, including ecdysteroids, triterpenes, saponins, flavonoids, anthraquinones, tannins, coumarins, alkaloids, and polysaccharides. Among them, flavonoids, anthraquinones, tannins, coumarins, and alkaloids were only putatively identified. β-Ecdysone, triterpenes, saponins, and polysaccharides are the chemical components most frequently identified and isolated from P. glomerata and possibly responsible for ethnopharmacological use and the biological activities of this species, with important in vitro and in vivo activities, such as anti-inflammatory, antidepressant, aphrodisiac, analgesic, gastroprotective, antioxidant, and prebiotic. CONCLUSIONS This review summarizes discussions about the P. glomerata species, highlighting its ethnopharmacological, chemical, biotechnological, and nutraceutical importance. New scientific studies on this species are encouraged in the search for new therapeutic molecules with pharmaceutical potential and nutraceutical applications.

Abstract
Pfaffia glomerata extract (PGE) has a variety of biological activities. However, its ameliorative effect on and exact working mechanism in male sexual dysfunction are still poorly understood. This study aims to evaluate the ameliorative effect of PGE on paroxetine (PRX)-induced sexual dysfunction in male mice and uses molecular docking technology to investigate its underlying mechanism. In this work, PRX-induced sexual dysfunction was caused and PGE was gavaged in mice for 28 days. The results show that PGE significantly improved the sexual performance of mice and reduced the damage to testicular tissues. Further studies showed that PGE restored serum sex hormones to normal levels and increased nitric oxide (NO) and cyclic guanosine monophosphate (cGMP) levels as well as nitric oxide synthase (NOS) activity in penile tissues, while also decreasing phosphodiesterase-5 (PDE-5) activity, thereby maintaining normal penile erection in mice. In addition, PGE improved the activities of enzymes (LDH, ACP, and ALP) related to energy metabolism in the testis and significantly increased sperm count and viability in mice. Furthermore, the molecular docking results show that all eight compounds in PGE could form a stable complex with PDE-5 and inhibit the activity of PDE-5. In conclusion, PGE had an ameliorative effect on PRX-induced sexual dysfunction, suggesting that PGE has a potential protective effect on male sexual health.

Abstract
Pfaffia glomerata (Spreng.) Pedersen, popularly known as "Brazilian ginseng," is used as medicinal plant in Brazil to treat inflammatory diseases in general. Previous studies showed that its extract increases the nitric oxide (NO) levels. Knowing that NO downregulates steroidogenesis and that alterations in the action/production of androgens during perinatal life could alter testis development, the present studies sought to investigate the reproductive toxicity of Pfaffia glomerata on male mice exposed to hydroalcoholic extract in utero and during lactation. The present study shows that P. glomerata extract does not alter body weight, tubular diameter and testis function in male mice. Although a reduction in the testis weight was observed in the animals that received the highest dose directly in early post-natal life, our findings show clearly that P. glomerata may not act as an endocrine disruptor, and it is not an "antiandrogenic" compound that could lead to testicular dysgenesis syndrome.

Abstract
Pfaffia glomerata is a medically important species because it produces the phytoecdysteroid 20-hydroxyecdysone (20-E). However, there has been no ready-to-use transcriptome data available in the literature for this plant. Here, we present de novo transcriptome sequencing of RNA from P. glomerata in order to investigate the 20-E production as well as to understand the biochemical pathway of secondary metabolites in this non-model species. We then analyze the effect of photoautotrophy on the production of 20-E genes phylogenetically identified followed by expression analysis. For this, total messenger RNA (mRNA) from leaves, stems, roots, and flowers was used to construct indexed mRNA libraries. Based on the similarity searches against plant non-redundant protein database, gene ontology, and eukaryotic orthologous groups, 164,439 transcripts were annotated. In addition, the effect of photoautotrophy in two genes putatively involved in the 20-E synthesis pathway was analyzed. The Phantom gene (CYP76C), a precursor of the route, showed increased expression in P. glomerata plants cultured under photoautotrophic conditions. This was accompanied by increased production of this metabolite indicating a putative involvement in 20-E synthesis. This work reveals that several genes in the P. glomerata transcriptome are related to secondary metabolism and stresses, that genes of the P450 family participate in the 20-E biosynthesis route, and that plants cultured under photoautotrophic conditions promote an upregulated Phantom gene and enhance the productivity of 20-E. The data will be used for future investigations of the 20-E synthesis pathway in P. glomerata while offering a better understanding of the metabolism of the species.

Abstract
Cadmium (Cd) is toxic to plants and animals, making it necessary to develop strategies that seek to reduce its introduction into food chains. Thus, the aim of this study was to investigate whether silicon (Si) and selenium (Se) reduce Cd concentrations in Pfaffia glomerata medicinal plant and attenuate the oxidative stress promoted by this metal. These plants were cultivated in hydroponics under the following treatments: control (nutrient solution), 2.5 μM Se, 2.5 mM Si, 50 μM Cd, 50 μM Cd + 2.5 μM Se, 50 μM Cd + 2.5 mM Si. After 14 days of exposure to treatments, leaves and roots were collected for the determination of dry weight of shoot and roots, Cd concentrations, chlorophyll and carotenoids content, and biochemical parameters (lipid peroxidation and guaiacol peroxidase and superoxide dismutase activities). The data were submitted to analysis of variance and means were compared with Scott-Knott test at 5% error probability. Roots of P. glomerata plants showed a significant reduction on dry weight accumulation when exposed to Cd. However, both Se and Si promoted a significant reduction of deleterious effects of Cd. The Cd concentrations in the tissues were reduced in the presence of Se or Si. Plants treated with Cd together with Se or Si presented higher pigment content than those with only Cd, thus showing a reduction in the negative effects caused by this element. In the treatments in which Se and Si were added in the growth medium together with Cd, an activation of superoxide dismutase and guaiacol peroxidase enzymes was observed in the roots and shoot, which may have contributed to lower lipid peroxidation. Thus, Se and Si reduce Cd concentrations and have potential to ameliorate Cd toxicity in P. glomerata plants, which can be used to increase productivity and quality of medicinal plants.

Abstract
ETHNAOPHARMACOLOGIAL RELEVANCE In South America, the β-ecdysone ecdysteroid has been found in species of the genus Pfaffia Mart. Due to the similar morphology of its roots to the Panax ginseng C. A. Mey. (Korean ginseng), some species of this genus has been known as Brazilian ginseng and have been used as tonic and aphrodisiac, as well as for the treatment of diabetes and rheumatism. AIM OF THE STUDY Here we report a cytogenotoxic evaluation of β-ecdysone (a natural ecdysteroid found in plants) in Rodent Bone Marrow Micronuclei and Allium cepa Assays. MATERIALS AND METHODS Three β-ecdysone (pure) concentrations (based in human therapeutic dosage) were used in the Micronucleus Assay. The animals were treated during two consecutive days. Micronucleated cells were counted in 2000 polychromatic erythrocytes per animal. For A. cepa L. Assay, one β-ecdysone concentration was analyzed. The onions bulbs were exposed for 24h. RESULTS The Micronucleus Assay showed genotoxic effects for all treatments, expressed by an increase of micronucleated cells. In A. cepa L. Assay, cell abnormalities associated to the malfunction/non-formation of mitotic spindle (aneugenic effect) and chromosomal bridges (clastogenic effect) were observed. CONCLUSIONS The results indicate a cytogenotoxic activity of β-ecdysone. Therefore, the popular use of Pfaffia and others species containing β-ecdysone should be considered with caution.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paffia spp (Amaranthacea) has a widespread use of in Brazil as a possible hormonal supplement and a substitute of Panax ginseng, although information on its reproductive effects is missing. AIM OF THE STUDY To evaluated possible anabolic-androgenic or anti-androgenic effects of Pfaffia glomerata (PG) extract using intact eight-months-old male rats and pre-pubertal castrated rats. MATERIALS AND METHODS Three different dose levels of PG (8.5, 30 and 85 mg/kg/day) were administered to eight-months-old rats for 28 days or to castrated males for 7 days (Hershberger assay). In the experiment with intact animals, 24h fecal samples were collected for quantification of fecal metabolites of androgens throughout treatment. At the end of the treatment period, animals were euthanized for evaluation of serum testosterone, reproductive organ weights, number of spermatids per testis, diameter of seminiferous tubules and cross-sectional area of soleus muscle fibers. In the Hershberber assay, androgenic or anti-androgenic effects were evaluated by the weights of androgen-dependent tissues: ventral prostate, seminal vesicle, glans penis and levator ani muscle/bulbocavernosus muscle. RESULTS No effects were observed in the concentrations of fecal metabolites of androgens monitored during the treatment of intact eight-months-old rats. Moreover, at the end of treatment, no changes were seen in any of the investigated parameters. In the Hershberger assay, the PG extract did not induce androgenic or anti-androgenic effects at the dose levels tested. Significant effects were only observed in animals treated with testosterone and testosterone plus flutamide, which were used as positive controls for androgenicity and anti-androgenicity, respectively. CONCLUSIONS At the dose levels tested, PG extract does not induce anabolic-androgenic or anti-androgenic effects in rats.
