“…The antioxidant activity of Apodus oryzae (R2MC3A), among other isolates in this study, was the highest (60.92 µg/mL) and confirmed to contain a phenolic compound (Table 2); achieving the total phenolic content (TPC) 96.10 mg gallic acid equivalent per g sample (data not shown here). The detection of TPC content clearly supported other findings on antioxidant capacity closely related with TPC (Sadeghi et al, 2015;Jeong et al, 2017;Hidayat et al, 2018;Kim et al, 2018). Although, the specific phenolic compound was not yet identified, the phenolic content itself is important due to its unique structure for redox property which acts as high reducing agents, hydrogen donators, and singlet oxygen quenchers which may lead Table 2.…”

Several species of Aquilaria and Gyrinops are native to Indonesia and well known as agarwood-producing trees with a high economic value. Their bioactive compounds have a wide spectrum of uses, such as in medicine and cosmetics. These genera have undergone extensive search for novel bioactive compounds. The purpose of this study was to isolate, identify, and characterize the endophytic fungi community associated with Aquilaria malaccensis, A. microcarpa, Gyrinops versteegii, and A. crassna trees and investigate their bioactive properties as antioxidant agents and antagonists. A total of 50 fungi were successfully isolated from different tissues of the four species of agarwood-producing trees. Two isolates exhibited strong antioxidant activity, namely, Apodus oryzae (R2MC3A, IC 50 60.92 mg/mL) and Diaporthe sp. (P1DS1[C], IC 50 76.65 mg/mL). Two isolates, Pestalotiopsis theae (P3BS3[B]) and Curvularia sp. (P2CD3A), showed >75% antifungal activity against pathogenic Fusarium solani. The results revealed that endophytic fungi associated with the studied agarwood-producing trees had potential antioxidant and antifungal activities for further applications in biotechnology.

“…The leaf essential oil of N. ellipsoidea was dominated by (E)-β-ocimene (87.6%). (E)-β-Ocimene was also found to be the dominant compound (85.6%) in the leaf essential oil of N. polycarpa from Vietnam [32], and one of the major components in the leaf essential oils of N. sericea from Korea (13.3%) [38], N. variabillima from Taiwan (13.4%) [39], and N. aciculata from Korea (9.7%) [40]. In contrast, (E)-β-ocimene was only a minor component in the leaf oils of N. australiensis, N. brassii, or N. dealbata from Australia [41], and N. pallens from India [42], and was not observed in N. foliosa leaf essential oil from India [43].…”

The Lauraceae is a family rich in aromatic and medicinal plants. Likewise, essential oils derived from members of this family have demonstrated a myriad of biological activities. It is hypothesized that members of the Lauraceae from Vietnam will yield essential oils that may be useful in controlling mosquito populations and treating microbial infections. In this work, the leaf essential oils of eleven species of Lauraceae (Beilschmiedia erythrophloia, B. robusta, B. yunnanensis, Cryptocarya concinna, C. impressa, C. infectoria, Litsea viridis, Machilus balansa, M. grandifolia, Neolitsea ellipsoidea, and Phoebe angustifolia) have been obtained by hydrodistillation and the chemical compositions analyzed by gas chromatography – mass spectrometry (GC-MS) and gas chromatography with flame ionization detection (GC-FID). The essential oils were screened for larvicidal activity against Aedes aegypti, Ae. albopictus, and Culex quinquefasciatus, and for antimicrobial activity against Enterococcus faecalis, Staphylococcus aureus, Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Salmonella enterica, and Candida albicans. The leaf essential oil of N. ellipsoidea, rich in (E)-β-ocimene (87.6%), showed excellent larvicidal activity against Ae. aegypti with a 24 h LC50 of 6.59 μg/mL. The leaf essential oil of C. infectoria, dominated by germacrene D (55.5%) and bicyclogermacrene (11.4%), exhibited remarkable larvicidal activity against Cx. quinquefasciatus (48 h LC50 = 0.40 μg/mL). N. ellipsoidea leaf essential oil also demonstrated notable antibacterial activity against E. faecalis and B. cereus with minimum inhibitory concentration (MIC) values of 16 μg/mL, while the leaf essential oil of C. impressa showed excellent anticandidal with an MIC of 16 μg/mL. Leaf essential oils from the Lauraceae should be considered for utilization as alternative agents for controlling mosquito populations and as antimicrobial agents.

“…Recent domestic studies have reported that the tree has the potentials on the aldose reductase inhibition, fat degradation, glycation, anti-elastase activity and anti-inflammation as well as antioxidant activity (Kim and Oh, 1999;Kim and Kim, 2003;Kim and Kang, -2 -2005;Kim et al, 2009;Jeong et al, 2017;Kim et al, 2015;Jung et al, 2017). However, there is a little studies on the chemical constituents of the tree in domestic because it has toxic although some studies had already done about the biological activities and the analysis of GC-MS on volatile components (Shibuya et al, 1978).…”

Japanese anise (Illicium anisatum L.) leaves were collected and ground after drying, then immersed with 50 % aqueous acetone for 3 days. After filtration, the extracts were fractionated with n-hexane, chloroform (CHCl 3 ), ethylacetate (EtOAc) and H 2 O, and then freeze dried after concentration. A portion of EtOAc (3.12 g) and H 2 O (6.08 g) soluble fractions were chromatographed on a Sephadex LH-20 column with various aqueous MeOH solution to isolate the compounds.Compound 1 ((+)-catechin) was isolated from EtOAc soluble fraction. Compounds 2 (quercetin), 3 (quercitrin) and 4 (2''-O-rhamnosylvitexin) were isolated from H 2 O soluble fraction.For the first time, quercitrin (3) and 2''-O-rhamnosylvitexin (4) of the isolated compounds were obtained from the extracts of japanese anise leaves.
