The kapok aqueous extract is combined with a pharmaceutically acceptable carrier or excipient to form a pharmaceutical composition. The kapok aqueous extract can be prepared into any convenient form, such as tablets, capsules, and powders. , Granules, liquids, etc., or the kapok water extract is combined with other foods or beverages for the organism to take orally in a form suitable for consumption.

又,本發明之木棉花水萃物係可以供投予一所需個體,例如以2.5~5毫克/公斤體重之劑量投予該所需個體,使該木棉花水萃物係所含有之活性成分得以於該所需個體體內作用,而可以減緩木瓜蛋白酶所誘發 的退化性關節炎症狀。 In addition, the kapok aqueous extract of the present invention can be administered to a desired individual, for example, at a dose of 2.5 to 5 mg / kg body weight, the desired individual can be administered to make the kapok aqueous extract active. The ingredients work in the body of the desired individual and can slow down the symptoms of degenerative arthritis induced by papain.

其中,該木棉花水萃物較佳係可以藉由一包含以下步驟之方法所製得:提供一木棉花樣品;以水作為一萃取溶劑萃取該木棉花樣品;及將木棉花粗萃液進行濃縮,以獲得該木棉花水萃物。 Among them, the aqueous extract of kapok is preferably prepared by a method comprising the following steps: providing a kapok sample; extracting the kapok sample with water as an extraction solvent; and performing a crude kapok extract Concentrated to obtain the aqueous extract of kapok.

詳而言之,係可以預先將該木棉花樣品於110~120℃之溫度下進行乾燥(將100克木棉花樣品乾燥至20克),得到一木棉花乾燥物;此外,該木棉花樣品亦可以預先碎成粉粒(粒徑約為1~2mm),以增加該木棉花樣品與該萃取溶劑之接觸表面積,藉此提升後續萃取之萃取效率。 Specifically, the kapok sample can be dried in advance at a temperature of 110 to 120 ° C (a 100 g kapok sample is dried to 20 g) to obtain a dried kapok material; in addition, the kapok sample is also It can be crushed into powder particles (particle size is about 1 ~ 2mm) in advance to increase the contact surface area of the kapok sample and the extraction solvent, thereby improving the extraction efficiency of subsequent extraction.

舉例而言,每4.8公斤之木棉花樣品係能夠混合該萃取溶劑,使二者總體積達80公升,並於115~125℃之溫度、0.35~0.5Kg/cm2G之壓力下進行萃取1.5~3小時,上述萃取亦可以重複數次,使該木棉花樣品所富含之活性成分可以完整溶出於該萃取溶劑,此為本發明所屬技術領域中具有通常知識者所廣泛應用,在此不加以贅述。 For example, every 4.8 kg of kapok sample can be mixed with the extraction solvent so that the total volume of the two reaches 80 liters, and the extraction is performed at a temperature of 115 to 125 ° C and a pressure of 0.35 to 0.5 Kg / cm 2 G. For ~ 3 hours, the above extraction can also be repeated several times, so that the active ingredients contained in the kapok sample can be completely dissolved in the extraction solvent. This is widely used by those with ordinary knowledge in the technical field to which this invention belongs. To repeat it.

前述之木棉花粗萃液可以經過減壓濃縮及冷凍乾燥,以獲得該木棉花水萃物,藉由此一程序,係可以使該木棉花水萃物之活性成分更加濃縮,是以僅需使用少量之該木棉花水萃物即可以發揮最佳療效。 The aforementioned crude extract of kapok can be concentrated under reduced pressure and freeze-dried to obtain the aqueous extract of kapok. By this procedure, the active ingredients of the aqueous extract of kapok can be more concentrated. Use a small amount of this kapok water extract for best results.

為證實本發明之木棉花水萃物係可以減緩木瓜蛋白酶所誘發的退化性關節炎症狀,遂將每4.8公斤之木棉花樣品萃取所得之木棉花粗萃液,經過減壓濃縮及冷凍乾燥獲得共800克之木棉花水萃物粉末,另將5克之木棉花水萃物粉末溶於20毫升之水後,進行以下試驗。 In order to confirm that the aqueous extract of kapok of the present invention can reduce the symptoms of degenerative arthritis induced by papain, a crude kapok extract obtained by extracting every 4.8 kg of kapok sample was obtained by concentration under reduced pressure and freeze-drying. A total of 800 grams of kapok water extract powder was dissolved. After 5 grams of kapok water extract powder was dissolved in 20 ml of water, the following test was performed.

(A)跑步功能試驗 (A) Running function test

本試驗係選用SD大鼠(Sprague Dawley rat)進行試驗,係於右膝關節(knee joint)注射木瓜蛋白酶(papain),以誘發退化性關節炎的發生。 This test was performed using SD rats (Sprague Dawley rats). The right knee joint was injected with papain to induce the occurrence of degenerative arthritis.

續分別以如第1表所示之木棉花水萃物連續經口灌食各組 大鼠共3個月(每天一次)後,讓各組大鼠於跑步機(treadmill machine)上跑步(跑步機的速度為16m/s),並記錄各組大鼠持續跑步的時間。 Continue to orally administer the kapok water extract as shown in Table 1 to each group of rats for 3 months (once a day), and then let the rats of each group run on a treadmill machine (run The speed of the machine is 16m / s), and the continuous running time of each group of rats is recorded.

請參照第1圖所示,相較於未經口灌食木棉花水萃物的第A0組大鼠,經口灌食濃度為2.5~5mg/kg的木棉花水萃物的第A1、A2組大鼠均可以於跑步機上持續跑步較長的時間,顯示本發明木棉花水萃物的投予可以有效降低木瓜蛋白酶所誘發的退化性關節炎症狀。 Please refer to Fig. 1. Compared with group A0 rats, which were not orally administrated the water extract of Kapok, the animals were administrated with the water extracts A1 and A2 of Kapok cotton at a concentration of 2.5-5 mg / kg. All rats in the group can continue to run on the treadmill for a longer period of time, showing that the administration of the aqueous extract of kapok of the invention can effectively reduce the symptoms of degenerative arthritis induced by papain.

(B)負重功能試驗 (B) Load-bearing function test

本試驗同樣以木瓜蛋白酶於SD大鼠的右膝關節誘發退化性關節炎的發生,續分別以如第2表所示之木棉花水萃物連續經口餵食各組大鼠共3個月(每天一次)後,分別讓各組大鼠僅以後肢站立,並記錄兩側後肢的負重差值。 In this test, papain induced the occurrence of degenerative arthritis in the right knee joint of SD rats. The rats were continuously fed orally with the kapok water extract as shown in Table 2 for a total of 3 months ( Once a day), the rats in each group were allowed to stand only on the hind limbs, and the weight difference between the hind limbs on both sides was recorded.

請參照第2a、2b圖所示,未經口灌食木棉花水萃物的第B0組大鼠會由於右後肢退化性關節炎的發生而減少右後肢的負重,經口灌食濃度為2.5~5mg/kg的木棉花水萃物的第B1、B2組大鼠,無論在連續餵 食1個月或3個月均能夠以兩側後肢平均負擔其體重,同樣顯示本發明木棉花水萃物的投予可以有效降低木瓜蛋白酶所誘發的退化性關節炎症狀。 Please refer to Figures 2a and 2b. Group B0 rats without oral gavage of Kapok water extract will reduce the weight of the right hind limb due to the occurrence of degenerative arthritis of the right hind limb. The oral concentration is 2.5. Rats in groups B1 and B2 of ~ 5mg / kg of kapok water extract can bear their body weight evenly on both hind limbs regardless of continuous feeding for 1 month or 3 months, which also shows the kapok water extract of the present invention Administration can effectively reduce the symptoms of degenerative arthritis induced by papain.

綜合上述,本發明之木棉花水萃物的用途係藉由萃取自木棉花之活性成分,可以減緩木瓜蛋白酶所誘發的退化性關節炎症狀,因而可以應用於製備治療退化性關節炎的藥物,為本發明之功效。 In summary, the use of the kapok aqueous extract of the present invention is to reduce the symptoms of degenerative arthritis induced by papain by using the active ingredients extracted from kapok, so it can be applied to the preparation of medicines for degenerative arthritis. It is the effect of the present invention.
