Embodiment 1
[0040] Embodiment 1: Extraction and separation of Tongkat Ali
[0041] Weigh 100g of Tongkat Ali root tablets (purchased from Anguo City Qingfengtang Chinese Herbal Pieces Co., Ltd.) and place it in a 1L round bottom flask, add 5 times the volume of 10% ethanol solution, put it in a heating mantle and heat for 4h, continuously Extract 5 times, collect and combine the extracts, concentrate and dry under reduced pressure to obtain the crude extract, then use 0-100% aqueous ethanol for gradient elution, the elution flow rate is 3BV / h, collect 30% gradient eluent , and concentrated and dried under reduced pressure to obtain a dry product, collected 30% ethanol eluted fraction (hereinafter referred to as "F2", that is, the Tongkat Ali extract of the present invention), and stored at -20°C.
Embodiment 2
[0042] Embodiment 2: Extraction and separation of Tongkat Ali
[0043] Weigh 100g of Tongkat Ali root tablets into a 1L round bottom flask, add 5 times the volume of 15% ethanol solution, put it in a heating mantle and heat for 4h, extract continuously for 5 times, collect and combine the extracts, and depressurize Concentrate and dry to obtain the crude extract, and then carry out gradient elution with 0-100% aqueous ethanol, the elution flow rate is 3BV / h, collect the 25% gradient eluent, and concentrate and dry under reduced pressure to obtain a dry product, collect 25% The ethanol eluted fraction (hereinafter referred to as "F2", ie the Tongkat Ali extract of the present invention) was stored at -20°C.
Embodiment 3
[0044] Embodiment 3: Preparation of Tongkat Ali Extract (F2) Phospholipid Complex
[0045] S1, take by weighing 0.10 g of the Dongkat Ali extract (F2) of Example 1, 0.20 g of soybean lecithin, and mix the Tongkat Ali extract with the phospholipid;
[0046] S2, add absolute ethanol 5mL;
[0047] S3, reflux and stir at 40°C for 2 hours, the stirring speed is 500-800rpm, until clarification;
[0048] S4, the reaction liquid was evaporated under reduced pressure at 45° C., ethanol was removed, and after vacuum drying for 24 hours, the Tongkat Ali phospholipid complex was obtained.
[0049] The formation of the Tongkat Ali complex obtained in S4 was confirmed by differential scanning calorimetry and Fourier transform infrared spectroscopy, as shown in figure 1 and figure 2 shown.
