High-speed counter-current chromatography (HSCCC) was successfully used for isolation and purification of 6-gingerol, 6-shogaol, 8-gingerol and10-gingerol from the crude ethanol extract of ginger by a consequently stepwise elution which was performed by eluting with the lower phase of n-hexane-ethyl acetate-methanol-water (5.5:5:5.5:5) first and then eluting with the lower phase of n-hexane-ethyl acetate-methanol-water (7:5:7:5), when the upper phase of n-hexane-ethyl acetate-methanol-water (5.5:5:5.5:5) was used as the stationary phase in the head to tail elution mode. The preparative HSCCC separation was performed on 500 mg of the crude extract yielding pure 6-gingerol (12 mg), 6-shogaol (2 mg), 8-gingerol (4 mg) and 10-gingerol (4 mg) at purities of 92.7, 96.8, 91.2 and 92.3 %, respectively, as determined by high performance liquid chromatography (HPLC). HSCCC is a powerful technique for isolation and separation of chemical composition from ginger.

Since time immemorial, the Indian medical system, particularly Ayurveda and Siddha, has prioritised prevention and health over symptoms and drugs. Siddha, an Indian system of medicine, originated in ancient Thamilakam (currently Tamil Nadu, India). The combination of Inji (Zingiber officinale Roscoe), Sukku (Zingiber officinale Roscoe) and Kadukkai (Terminalia chebula Retz) as herbal therapy with numerous chemical constituents can be considered a better pharmacological approach than consuming individual ingredients and/or chemical constituents. This review is an attempt to summarize the evidence related to the anti-obesity and weight-lowering effects of ginger and T. chebula. The overall view shows an anti-hyperlipidemic effect of Zingiber officinale and Terminalia chebula.

Identification of protease enzyme in salep orchid tubers, and investigation of the usability of the enzyme in casein and gluten hydrolysis

In recent years, due to many diseases transmitted from animals to humans (coronavirus disease, severe acute respiratory syndrome, mad cow, and bird and swine flu), consumers are concerned about the use of protease enzymes derived from animal sources in the production of food products. These concerns have increased the demand for protease enzymes of plant origin. The fact that very few of the protease enzymes used in the production of foodstuffs are produced from plant sources has led researchers to seek a new source of plant-based protease. In the present work, the protease enzyme was isolated from the tubers of the salep orchid (Dactylorhiza osmanica) by ammonium sulphate precipitation and size exclusion chromatography. The isolated protease had an optimal pH of 6.5 and an optimal temperature of 48°C. The Km value was 8.22 µM. The molecular mass of the enzyme was 31 kDa. The enzyme retained its 100% activity up to 21 h at 40°C. At 50°C, the enzyme maintained its 100% activity for up to 4 h. The isolated protease acquired from the salep orchid tubers hydrolysed α-, β-, and κ-casein, and formed new peptides larger than 15 kDa. The isolated enzyme is known to be effective in milk clotting, which is the first step of cheese making, and might also contribute to the production of cheese with specific flavours. However, the protease extracted from the salep orchid tubers cannot hydrolyse gluten at the same level.
