A comparative study of the antimicrobial and phytochemical properties between outdoor grown and micropropagated Tulbaghia violacea Harv. plants

In vitro antimicrobial synergism within plant extract combinations from three South African medicinal bulbs

“…The generally good antibacterial activity shown by both proportional extract yields and equal extract combinations of PE and DCM in almost all samples in this study, suggests that non-polar compounds interact more synergistically than the polar compounds. The trend is, however, consistent with most of the findings in other non-interaction studies, in which non-polar extracts demonstrated better antimicrobial activity than polar ones (Rabe and Van Staden, 1997;McGaw et al, 2001;Ncube et al, 2011b).…”

Improved micropropagation of Bacopa monnieri (L.) Wettst. (Plantaginaceae) and antimicrobial activity of in vitro and ex vitro raised plants against multidrug-resistant clinical isolates of urinary tract infecting (UTI) and respiratory tract infecting (RTI) bacteria

“…With a similar approach, a comparative study was conducted by few researchers in recent past [41][42][43][44]. Some of them reported the in vitro plants exhibited more antimicrobial activity as compared to ex vitro plants [42,43], whereas the majority of them reported ex vitro plants are superior or more or less comparable as compare to in vitro plants [41,44]. The in vitro plants, producing secondary metabolites at a primary stage of growth, provides an opportunity for fast production of pharmacologically important compounds that can be utilized for medicinal purposes [41].…”

Thymus lotocephalus wild plants and in vitro cultures produce different profiles of phenolic compounds with antioxidant activity

“…The production of secondary metabolites is influenced by environmental and physiological conditions (Barros et al 2012;Ncube, Ngunge, Finnie, & Van Staden, 2011). We found that caffeic acid, luteolin and apigenin were present at higher concentrations in the water/ethanol extract from wild plants than the extracts from in vitro cultures (Table 1).…”
