... The whole plant is traditionally used as a cardiotonic, purgative, expectorant, tonic and for rheumatism, quick relief of a common cough and cold and in ear pain, The roots are used as a febrifuge in snake bite and hemorrhoids (Ikewuchi et al., 2010). Additionally, the plant showed various pharmacological activities such as antitumor, antimicrobial, antidiabetic, leaves exhibited anticancer and antioxidant property, the whole plant also possesses antioxidant, analgesic (Obydulla, 2016). Preliminary phytochemical screening of leaves extract showed the presence of many secondary metabolites such as alkaloids, flavonoids, saponins. ...
The present study was carried out to evaluate the response of the anise plant seeds to the plant growth regulator gibberellin (GA 3) and the effect of the saponins extract of Sansevieria hyacinthoides leaves on the seeds germination and seedling growth. Various plant extracts were used to improve crop yield and quality, being safe for the environment. Firstly, the toxic effect of the leaf extract was estimated using the phytotoxicity assay on radish seeds. This assay showed insignificant decrease in root length at 1000 µg/ml, whereas an increase in root growth was observed at concentrations 10 and 100 µg/ml. Similarly, stimulatory effect on the percentage of seeds germination was observed reached (100%) at 10µg/ml. Low concentrations (0.0, 1.25, 2.5, 5.0, 10.0 µg/ml) of saponin extract were applied to test the germination and growth of anise plant. Leaves extract increased the germination of anise seeds and enhanced the growth of root length significantly at 10µg/ml in comparison with control treatment (0µg/ml). The root lengths were 1.3 and 2.3cm after 4 and 7days respectively and the percent of germination reached 100% after only 7 days. The lower concentrations did not have any effect on seeds germination rate with little effect on root length. It is concluded that the saponins extracted from Sansevieria leaves are safe and has no toxic effect and possess clear activity similar to the effect of the plant growth regulator gibberellin on increasing seed germination rate and promoting seedling growth.
... Sansevieria subclade S2:-Subclade S2 is strongly supported in cpDNA analyses ( Fig. 2B; BS = 75, PP = 1.0) and moderately supported in combined analyses ( Fig. 3; BS = 52, PP = 1.0). It comprises three morphologically similar species from East Africa (S. dumetescens, S. perrotii, S. powellii) and a morphologically distant species (S. roxburghiana) from India, Bangladesh, Sri Lanka and Indonesia (Dulla 2016). The East African species are united by their paniculate branching inflorescences (S. sect. ...
The evolutionary history of the dracaenoid genera Dracaena and Sansevieria (Asparagaceae, Nolinoideae) remains poorly resolved, despite long-recognised issues with their generic boundaries and increased attention paid by both horticulturalists and taxonomists. In this study we aim to: (1) elucidate evolutionary relationships within and between Dracaena and Sansevieria using molecular phylogenetic inference of both nuclear (nDNA) and plastid (cpDNA) markers, (2) examine the infrageneric classifications of each genus, and (3) revise the circumscription of the dracaenoids in light of morphological and phylogenetic evidence. In total, we sampled 21 accessions of Dracaena (ca. 19 species), 27 accessions of Sansevieria (ca. 26 species), and six outgroup taxa. Phylogenetic analyses were based on nucleotide sequences of two non-coding plastid DNA regions, the trnL-F region (trnL intron and trnL-trnF intergenic spacer) and rps16 intron, and the low-copy nuclear region At103. Phylogenetic hypotheses were constructed using maximum parsimony, maximum likelihood, and Bayesian inference. Individual datasets were analysed separately and, after testing for congruence, as combined datasets. We recovered instances of soft incongruence between nDNA and cpDNA datasets in Sansevieria, but general trends in the dracaenoids were congruent, although often poorly supported or resolved. The dracaenoids constitute a strongly supported monophyletic group. Dracaena was resolved as a paraphyletic grade embedded with two clades of Sansevieria, a primary clade comprising most species, and a secondary clade including S. sambiranensis, a distinctive species from Madagascar. The backbone of our phylogeny was only resolved in nDNA analyses, but combined analyses recovered strongly supported species groups. None of the previous infrageneric classifications were supported by our phylogeny, and biogeographic groupings were frequently more significant than morphology. More work is needed to resolve internal relationships in the dracaenoids, but we support a recent proposal to recognise a broadened circumscription of Dracaena that includes Sansevieria. We provide a generic description for the recircumscribed Dracaena and new combinations for several species of Sansevieria in Dracaena.
Soil pollution caused by toxic and hazardous chemical contaminants is in high enough concentrations to be of risk to plants, wildlife, humans and certainly for soil to itself. Pot experiments were conducted to investigate the phytoextraction capacity of an ornamental plant Sansevieria roxburghiana cultivated in soil artificially contaminated with 200, 400, and 600 mg kg⁻¹ of zinc (Zn) treatments including control for 6 weeks. The soil was amended with garlic and cilantro extracts as the natural irrigation solutions (metal chelants). Garlic application significantly enhanced the Zn accumulation and was found to be the most efficient chelating amendment, increasing concentrations of Zn in roots from 65 mg kg⁻¹ to 423 mg kg⁻¹ dry weight (DW) soil. The phytochemical screening of acetone and ether extracts of S. roxburghiana plant samples revealed the presence of biologically active phytochemicals. Thin layer chromatography (TLC) of plant extracts revealed antibacterial efficacy against pathogenic bacterial strain. The plant samples were also characterized by thermogravimetric analysis and differential scanning calorimetric technique. The use of ornamental plant and varied irrigation solutions in our present study revealed positive effects on growth and phytoextraction together with an improvement of the soil quality.
Over-prescription of medicines leads to some crucial health issues like resistance, non-specificity, etc. Therefore, a human consumes various natural foods, therapeutics, and nutritional supplements to combat this problem. Various therapeutic properties of secondary metabolites such as anticancer, anti-inflammatory, and antibacterial properties are important in drug discovery and medicinal application. These natural products has replaced synthetic materials, resulting in a great deal of sustainability, rational use and preservation of biodiversity. This review described the potential therapeutic applications of secondary plant metabolites found in Himalayan Indian plants. The database contains 45 plants to treat various diseases such as cancer, inflammation, and microbial infections. Besides authorized ITIS names, it includes Hindi names, family names, and active constituents. The most important information about the molecules can be found in the hyperlinks for the active constituents. It includes structures (two-dimensional and three-dimensional), names and identifiers, chemical and physical properties, spectral information, biochemistry, literature and patents. The review also references various phytochemicals responsible for preventing COVID-19. Despite several challenges in manufacturing natural products, researchers may conduct research to produce successful medicines with few side effects.
