Essential oils hold tremendous medicinal attributes and are greatly exploited industrially worldwide. Lindera is an important genus of the Lauraceae family of plants which are known for their medicinal values. In the present study, eleven studies reported on Lindera essential oils were selected and reviewed. Then the variability of essential oil components in the genus Lindera were assessed by multivariate analysis. The chemical analysis enabled the identification of qualitative and quantitative differences among the essential oils. The essential oils were characterized by high proportions of germacrene B, spathulenol, nerolidol, ?-caryophyllene, dihydromyrcene, furanosesquiterpenoid, sesquithuriferol, and linalool. Then, the differences in the chemical profiles of the essential oil were confirmed by the multivariate statistical analysis, which was determined via principal component analysis (PCA) and hierarchical clustering analysis (HCA). The analysis classified the Lindera species i.....

INTRODUCTION: In every country, an adequate and reliable blood supply can be assured by a stable base of regular, voluntary, and unpaid blood donors. However, with the strike of COVID-19 around the world, fewer donors have come forward to donate blood since the government's movement control order. Therefore, to ensure the blood supply is always sufficient, this study discussed the Malaysians' motivation and intention to donate blood during the COVID-19. MATERIALS AND METHODS: The structural focus group discussion was conducted among nine informants. The informants are classified into four groups, which are non, first-time, regular, and lapsed (repeated/occasional) blood donors. RESULTS: It indicated that the regular and lapsed group of blood donors were motivated by the satisfaction of donating blood. Meanwhile, first-time donors are motivated to donate blood because of extrinsic rewards. However, the donors attested that the movement control order restricted their movement to go to th.....
