In this work, we have successfully synthesized highly biocompatible and functionalized Dioscorea alata (D. alata) mediated silver nanoparticles with different quantities of its extract for the evaluation of proficient bactericidal activity and optical limiting behavior. The crystalline nature of the
From the fungal endophyte, Fusarium redolens Dzf2, isolated from rhizomes of the Chinese medicinal plant Dioscorea zingiberensis, beauvericin was obtained by TLC in combination with bioautographic antibacterial assay. The compound was identified by spectroscopic and physicochemical means. The median
Poly(l-lactic acid) (PLLA) has been the most commonly used polymer for making bioresorbable vascular scaffolds (BVS). Despite owning remarkable properties, BVS made from PLLA are facing higher rates of early thrombosis compared with permanent metallic scaffolds. To solve this issue, we modified the
BACKGROUND
Dioscorea bulbifera is an African medicinal plant used to treat microbial infections. In the present study, the methanol extract, fractions (DBB1 and DBB2) and six compounds isolated from the bulbils of D. bulbifera, namely bafoudiosbulbins A (1), B (2), C (3), F (4), G (5) and
OBJECTIVE
The aim of the study was to isolate and characterize the endophytic fungi from the rhizomes of the Chinese traditional medicinal plant Dioscorea zingiberensis and to detect their antibacterial activities.
RESULTS
After strict sterile sample preparation, nine fungal endophytes were isolated
Aqueous, methanolic and ethyl acetate extracts of 14 plants used in traditional Zulu medicine for treatment of ailments of an infectious nature were screened for antibacterial activity. Most of the activity detected was against gram-positive bacteria. Tuber bark extracts of Dioscorea sylvatica had
The biodegradable films, composed of carboxymethyl cellulose (CMC), glycerol, mucilage from Dioscorea opposita (DOM) and Ag nanoparticles, were prepared by a casting method and characterised including colour measurement, solubility, mechanical and water barrier properties etc. to fit the
Three norclerodane diterpenoids, diosbulbins K-M, and one analogous enolglycoside, diosbulbinoside G, together with four norclerodane diterpenoids, diosbulbins B, E, F and G, were isolated from rhizomes of Dioscorea bulbifera. Their structures were established by spectroscopic and chemical methods,
Five spirobisnaphthalenes, namely palmarumycin CP17 (1), diepoxin kappa (2), diepoxin eta (3), diepoxin xi (4), and diepoxin gamma (5), were isolated from the endophytic fungus Dzf12 associated with the medicinal plant Dioscorea zingiberensis C. H. Wright. Their structures were identified by
BACKGROUND
Opportunistic infections in AIDs patients is the leading cause of death in among them. HIV infection was reported as causes of increasing oxidative stress which may lead to progress of many syndrome. Thus medicinal plants as demonstrated antimicrobial and antioxidant activities would be
Antibacterial and antifungal activity of crude extracts of medicinally important and traditionally used yam plant, Dioscorea pentaphylla, from mid-Western Ghats was evaluated against 27 bacterial and 5 fungal clinical strains collected of the patients from infectious sources. The clinical strains
Two clerodane diterpenoids, Bafoudiosbulbins A 1, and B 2, together with five known compounds: tetracosanoic acid, 1-(tetracosanoyl)-glycerol, trans-tetracosanylferulate, beta-sitosterol and 3-O-beta-D-glucopyranosyl-beta-sitosterol were isolated from the tubers of Dioscorea bulbifera L. var sativa.
Two cyclotetrapeptides, henceforth named Provipeptides A (1) and B (2), along with five known diketopiperazines (3-7) were isolated from the liquid culture of marine Streptomyces sp. 161a recovered from a sample of sea grass Bryopsis sp. The structures of cyclotetrapeptides and diketopiperazines
The aim of this study was to determine the phenolic profile, antiproliferative, and pro-apoptotic activities of Asparagus acutifolius, Tamus communis, and Ruscus aculeatus aqueous extracts against human bladder (T24) and lung cancer (A549) cell lines. Antiproliferative activity of the extracts at
BACKGROUND
Development of an environmentally benign process for the synthesis of silver nanomaterials is an important aspect of current nanotechnology research. Among the 600 species of the genus Dioscorea, Dioscorea bulbifera has profound therapeutic applications due to its unique phytochemistry.
