“…However, the ethanol-based GJE extract was significantly less effective than was BHT (P < 0.05; Table 2) but showed stronger scavenging activity than those of some common fruits studied by Yan, Teng, and Jhi (2006). In addition, the fruit extract of Gardenia volkensii also exhibited moderate DPPH radical-scavenging activity, as reported by Jumaa and Majindaa (2007). Furthermore, DPPH Å -scavenging activity was highly correlated with phenolic and flavonoid contents (r 2 = 0.9988 and 0.9816 for water extract and r 2 = 0.9989 and 0.998 for ethanol extract, respectively).…”

“…have reported that samples extracted from peeled quince showed a higher radical scavenging capacity than those extracted from pulped quince. Juma and Majinda have reported that gardenia showed a moderate level of DPPH scavenging activity, which is consistent with the results obtained for the whole fruit tea infusions in our study. We observed that there was a moderately positive correlation between samples and the DPPH scavenging capacity (r=0.534, p ≤0.05) in the case of the whole fruit infusions.…”

This study was conducted to analyze the bioactive compounds and in vitro antioxidant capacity of tea infusions prepared from whole and ground medicinal fruits, including gardenia, jujube, magnolia, quince, and wolfberries. The dried medicinal fruit samples were ground, and then passed through a 60-mesh sieve (pore size, 250 μm). Hot water (80°C) infusions of whole and ground fruits were examined. In average of both whole and ground tea infusions, the maximum bioactive compounds were found in gardenia (β-carotene, lycopene, and vitamin C), magnolia (total chlorophyll and anthocyanin), quince (flavonoid), and wolfberries (phenolic), and the maximum antioxidant capacity was found in quince (ABTS and DPPH) and wolfberries (NSA). Whole fruit tea infusions showed a higher brightness than the ground fruit tea infusions. The total chlorophyll, anthocyanin, βcarotene, lycopene, phenolic, flavonoid, and vitamin C contents were found to be significantly (p � 0.001) higher in the ground fruit tea infusions than in the whole fruit tea infusions; additionally, the ground fruit tea infusions had a higher antioxidant capacity especially ABTS, DPPH and NSA. Therefore, the ground fruit tea infusions appeared to be more powerful with regard to the contents of bioactive compounds and antioxidant capacities than the whole fruit tea infusions.

“…Several studies substantiate the positive correlation of quality of phenolics with the DPPH free radical scavenging effect [32,33]. Although methanolic fruit extract of G. latifolia was significantly less effective than ascorbic acid but showed stronger scavenging activity than those of the fruit extracts of Gardenia volkensii [34] and Gardenia jasminoides [35]. From this study, it is imperative that the methanolic fruit extract of G. latifolia has showed significant antioxidant activity owing to the presence of phenolic compounds.…”

Gardenia latifolia Ait. (Rubiaceae) is also known as Indian Boxwood is a small deciduous tree often growing in southern states of India. In the present study, phytochemical profiling of methanolic extract of G. latifolia fruits were carried out using FTIR and LC-MS/MS analysis. Besides, its antioxidant and antimicrobial potential have been analysed using DPPH activity, differential pulse voltammetry and resazurin microtiter assay, respectively. Phytochemical profiling revealed the presence of 22 major diversified compounds and main were 3-caffeoyl quinic acid (chlorogenic acid), 3,4-Di-O-caffeoyl quinic acid, 6-O-trans-feruloylgenipin gentiobioside, 10-(6-O-trans sinapoyl glucopyranosyl) gardendiol, isoquercitrin, scortechinones, secaubryenol, iridoids and quercetin 3-rutinoside (rutin). The extract showed antioxidant activity (IC50 = 65.82) and powerful antibacterial activity with lowest minimum inhibitory concentration against Gram-positive Staphylococcus aureus (15.62 µg/µL), Bacillus subtilis (31.25 µg/µL) than gram negative Escherichia coli (62.5 µg/µL), Klebsiella pneumoniae (62.5 µg/µL), Pseudomonas aeruginosa (31.25 µg/µL). This study shows that the fruits of G. latifolia have tremendous potential to be used in food industries, phyto-therapeutics and cosmetic industries.
