In the present study the variations of biomass, essential oil content and composition of lemon verbena (Lippia citriodora) during different growth-exploitation phases from 27th May 2020 to 8th June 2021 were investigated. The uniform rooted cuttings were planted in the greenhouse under natural light. The aerial parts of lemon verbena at flowering stage were harvested at six times included 27th May (H1), 29th August (H2), 4th Nov. (H3), 17th Jan. (H4), 27th March (H5), and 8th June (H6). Hydro distillated essential oils were analyzed by using GC-FID and GC/MS techniques to determine the essential oil profile. Results showed a considerable variation in plant biomass, essential oil quantity and quality at different harvesting times. Plant biomass increased by 66.83% up to fourth harvesting time (H4) then decreased. During the studied harvesting frequencies the essential oil content of L. citriodora showed a sinusoidal trend. The highest essential oil content (0.858% v/w) and yield (17.95 L ha-1) were obtained at third harvesting time (H3) and in the followed harvesting times their contents were decreased. The observed changes in the essential oil composition of L. citriodora during different harvesting times were due to the relative proportions of constituents and the presence of new constituents. In the all essential oil samples, oxygenated monoterpenes represented by geranial (25.42-30.11%) and neral (19.81-24.19%) were the predominant compounds The highest ratio of monoterpenes to sesquiterpenes compounds (¡Ö5:1) was recorded in collected plants at third harvesting time.

This study analyzed the chem. composition and anti-osteoporosis activity of the n-hexane extract of Homalomena gigantea rhizome. Sixty compounds, representing 92.0% of the extract, were identified by gas chromatog.-mass spectrometry. Linalool (15.3%), oplopanone (9.8%), (¦¥)-¦Á-atlantone (5.6%), khusinol acetate (5.4%), bullatantriol (4.3%), and ¦Â-sitosterol (3.8%) were the main constituents. The anti-osteoporotic activity of the n-hexane extract was determined by measuring alk. phosphatase (ALP) activity, collagen content, and the mineralization of MC3T3-E1 cells. At concentrations of 4.0 and 20.0 ¦Ìg/mL, the n-hexane extract increased ALP activity by 8.2% and 23.7%, and increased collagen secretion by MC3T3-E1 cells by 114.9% and 112.4%, resp. At 4 ¦Ìg/mL, the extract significantly promoted the mineralization of MC3T3-E1 cells by as much as 133.2% compared to the neg. control. These results suggested that H. gigantea rhizome contains a natural anti-osteoporotic compound

8-Epidiosbulbin E acetate (EEA), a furan-containing diterpenoid lactone, is one of main component of Dioscorea bulbifera L.(DBL). It has been reported that EEA induces severe hepatotoxicity in mice and that its hepatotoxicity is associated with metabolic activation. The present study demonstrated that exposure to EEA (50, 100 or 200 ¦ÌM) induced DNA damage, including significant DNA fragmentation, increases of tail DNA and olive tail moment, H2AX phosphorylation and PARP-1 activation, in cultured mouse primary hepatocytes. Similar observation was obtained in mice administered EEA at 50, 100 or 200 mg/kg. Pre-treatment with 10 ¦ÌM ketoconazole (KTC), 200 ¦ÌM vitamin C (VC), or 200 ¦ÌM glutathione Et ester (GSH-OEt) reversed the over-production of reactive oxygen species (ROS) induced by EEA and attenuated susceptibility of hepatocytes to EEA-induced cytotoxicity and DNA damage in mouse primary hepatocytes. In contrast, pre-treatment with 1.0 mM L-buthionine sulfoximine (BSO) potentiated over-production of ROS, cytotoxicity and DNA damage induced by EEA. In summary, EEA induced DNA damage in cultured primary hepatocytes and the liver of mice. ROS, possibly along with DNA alkylation, participated in the observed DNA damage.

In this study, we produced roasted, baked, steamed, and sun-dried green tea products using the same batch of fresh tea leaves (FTL) of Longjing 43 (Camellia sinensis var. sinensis), and explored processing effects on the metabolic profiles of four types of green teas (FGTs) using the widely targeted metabolomics. Results showed that 146 differential metabolites including flavonoids, amino acids, lipids, and phenolic acids were screened among 1034 non-volatiles. In addition, nineteen differential metabolites were screened among 79 volatiles. Most of non-volatiles and volatiles metabolites changed notably in different manufacturing processes, whereas there were no significant differences (p>0.05) in the levels of total catechins between FGTs and FTL. The transformation of metabolites was the dominant trend during green tea processing. The results contribute to a better understanding of how the manufacturing process influences green tea quality, and provide useful information for the enrichment of tea biochem. theory.
