BAB VI SIMPULAN DAN SARAN

B. Saran

1. Dilakukan penelitian lanjutan dengan dosis dan lama pemberian ekstrak daun kenikir (Cosmos caudatus Kunth.) yang lebih bervariasi untuk mengetahui efek yang optimum pada terapi terhadap pankreas tikus putih model diabetes melitus.

2. Dilakukan uji identifikasi senyawa aktif dan kadar antioksidan yang terdapat didalam ekstrak daun kenikir (Cosmos caudatus Kunth.) sebelum ekstrak digunakan untuk perlakuan penelitian.

3. Dilakukan penelitian lanjutan dengan menggunakan parameter yang lebih lengkap untuk menilai efek terapi terhadap pankreas tikus putih model diabetes melitus misalnya ekspresi insulin dan jumlah kerusakan sel β pulau Langerhans pankreas.
