ABSTRACT Plants and algae contain novel biocompounds with therapeutic potentials. These compounds are either embedded within the cell wall matrix or bonded with polymers at cell cytoplasm, which hinders release of bioactive compounds during extraction. Enzymatic hydrolysis of cell wall and cytoplasm polymers enhances the release of biocompounds while preserving their biological potencies. Previous works have focused more on comparative studies of different enzymes, whereas other process parameters, such as agitation speed, substrate particle sizes, hydrolysis time, degree of hydrolysis, and multistage extraction, have received less attention. This review examines the extent of studies in this area and highlight current research gaps to be explored in future researches.

The use of herbal preparations remained the main approach of folk medicine to the treatment of ailments and debilitating diseases. Initial intensive researches conducted on Lemongrass extracts (tea) may have showed conflicting evidences, however the resurgence in claims of folk medicine practitioners necessitated further inquiry into the efficacy of the tea. Lemongrass tea contains several biocompounds in its decoction, infusion and essential oil extracts. Anti-oxidant, anti-inflammatory, anti-bacterial, anti-obesity, antinociceptive, anxiolytic and antihypertensive evidences of lemongrass tea were clearly elucidated to support initial pharmacological claims. Lemongrass tea was non-toxic, non-mutagenic and receives wide acceptance among alternative medicine practitioners in several developing countries. This review therefore presents previous research activities, technologies and information surrounding bioactivities of lemongrass tea. Areas of future researches which may elucidate mechanisms of the biological properties of lemongrass extracts were highlighted.

ABSTRACT
Fish gelatins obtained from perch fish skin pretreated with various solutions containing acetic acid, sodium hydroxide (NaOH) and sodium chloride (NaCl) were successfully characterized for their nanostructure pattern using Field Emission Scanning Electron Microscopy (FESEM). Each pretreatment transformed collagen to gelatin with fibril, zigzag cracks, straight rods and cross-linked rods nanostructure patterns. Pretreatment solutions also affect the gel yield, gel-strength, amino acid profile and functional groups in perch gelatin as analyzed by Fourier Transform Infrared (FTIR) spectroscopy. Samples pretreated with NaCl, NaOH and acetic acid solution showed the highest gel yield (22.84%) and gel-strength (179.84g). FTIR spectra for perch gelatins also revealed weak C-N amide II and III bond stretches as well as weak C=O bond stretch.
