yucca gigantea/抗真菌藥

The antifungal activity of a crude steroidal glycoside extract from Yucca gloriosa flowers, named alexin, was investigated in vitro against a panel of human pathogenic fungi, yeasts as well as dermatophytes and filamentous species. The minimal inhibitory concentration (MIC) was determined by an agar

In the present study, the characterization and properties of silver nanoparticles from Yucca shilerifera leaf extract (AgNPs) were investigated using UV-visible spectroscopic techniques, zeta potential, and dynamic light scattering. The UV-visible spectroscopic analysis showed the absorbance peaked

Human giardiosis is a public health problem in Mexico, where the national prevalence was estimated to be up to 68%. Misuse of antiprotozoal drugs may result in low effectiveness and undesirable side effects. Research on natural products is a good strategy for discovering more effective antiparasitic

Resveratrol (3,4',5-trihydroxystilbene) has been reported to have a variety of anti-inflammatory, anti-carcinogenic, anti-fungal and anti-platelet effects. It occurs naturally in different medicinal plants. Recently, resveratrol and other related phenolic compounds including

Ten steroidal saponins with cis-fused A/B ring, including a smilagenin glycoside, elephanoside A (4), and the five furostanol bisdesmosides, elephanosides B-F (6-10), were isolated from the stems of Yucca elephantipes Regel. (Agavaceae). Their structures were determined by detailed chemical and

An extract of the leaves of Yucca smalliana Fern. (Agavaceae) showed potential antimicrobial activity. Employing a bioassay linked fractionation method, one of the active principles, namely yuccalan, was isolated as a new steroidal saponin. The structure of the new steroidal saponin was elucidated
