The leaves of C. asiatica (150 g) were used to extract phytochemicals in 1.5 L of 70% methanol solution in 3 h using a reflux extractor (MS-DM607, M-TOPS, Seoul, Korea). The filtered extracts were immediately treated to remove methanol in a rotary evaporator (N-1200 A, Eyela, Tokyo, Japan) under reduced pressure at 50 °C. The remnants were then frozen and freeze-dried in a dryer (Scanvac Coolsafe 95-15, Labogene, Lynge, Denmark) for 48 h, starting at temperature down to -95 °C under low pressure, which finally yielded a concentration of 21.6%.

Tetragonia tetragonoides (Pall.) Kuntze (NZS) leaves were collected from the ocean dunes of Shinan-gun, Jeonnam Province, Korea. The aerial part of the NZS (500 g) was obtained through hot-water extraction using 10 L of 30% alcohol at 80 °C for 2.5 h. The filtered extracts were immediately treated to remove the ethanol in a rotary evaporator (N-1200 A, Eyela, Tokyo, Japan) under reduced pressure at 45 °C. The remnants were then frozen and freeze-dried in a dryer (Scanvac Coolsafe 95-15, Labogene, Lynge, Denmark) for 48 h, starting at a temperature of −95 °C under low pressure, which finally yielded a concentration of 11.2% [23 (link)].
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
