Abstract

The addition of growth regulator is one of the critical success factors in in vitro cultures. 2,4-D as a plant regulator in media can stimulate the cell division, enlargement of the explants and promotes the formation and growth of callus. The purpose of this study was to determine the time of callus formation and to determine the best concentration of 2.4-D in inducing the growth of callus from leaf explants of Vanda sp. This research was conducted by experiment with completely randomized design, which consists of six levels of treatment concentration of 2,4-D i.e. 0 ppm; 1 ppm; 1.5 ppm; 2 ppm; 2.5 ppm; and 3 ppm. The parameters observed were the percentage of callus formation and the form of callus from Vanda sp leaf explants. The results were statistically analyzed by using MINITAB program version 17. Analysis of variance (ANOVA) was performed and the difference between means score/value was separated by F test at p < 0.05. The results showed that 2,4-D treatment give significant effect (F 5,12 = 3,20; p = 0,046 < 0,05) on the callus growth time and its percentage. Application of 2 ppm 2.4-D was the best concentration for accelerating the callus growth time (14.3 days after planting) and increasing the percentage of callus formation (83.3%). Most of callus type were proliferative callus (36.11%) and senescence callus (11.11%). The results of this research are very important to grow the callus from Vanda leaves orchid explant because it is very diffucult to grow.

Abstract

To reveal the dominant substances contribute to antidiabetic effect of Physalis angulata herbs, an antidiabetic test had been done  on chloroform fraction of the herbs eluted with methanol-ammoniak. Identification of active substances was done by GC-MS.  Antidiabetic test was done using 30 male mice  (Mus musculus) strain ddY. The blood samples was taken on day-7 and day-14. Results showed that sugar blood level of the treated mice was significantly decreased, and reached normal level on day-14. Identification with GC-MS revealed that dominant substances in chloroform fraction of Physalis angulata herbs were unsaturated fatty acids, i.e. Hexanoic acid, Hexadecanoic acid methyl ester, 9-Octadecenoic acid methyl ester, Oleic acid butyl ester, 9-Octadecenoic acid, 1,2-Benzendicarboxylic acid, and Aplysterylacetate.. Beside fatty acids it was also found Nordextromethorphan, an alkaloid substance. In conclusion, chloroform fraction of  Physalis angulata herbs had antidiabetic avtivity and the dominant substances were unsaturated fatty acids and alkaloid Nordextromethorphan.   ABSTRAK Untuk mengetahui senyawa dominan dalam herba ciplukan yang mempunyai efek antidiabetes, maka dilakukan uji antidiabetes fraksi kloroform yang dieluasi dengan metanol-amoniak, selanjutnya diidentifikasi kandungannya dengan kromatografi gas spektrofotometri massa (KGC-MS). Pengujian dilakukan dengan menggunakan 30 ekor mencit putih jantan (Mus musculus) galur ddY. Masing-masing mencit diambil sampel darahnya pada hari ke-7 dan hari ke-14, untuk diuji kadar gula darahnya. Hasilnya ketiga dosis menunjukkan penurunan kadar gula darah secara signifikan pada hari ke-7, tetapi penurunannya belum mancapai kadar normal, sedangkan pada hari ke-14 seluruh perlakuan menunjukkan penurunan kadar gula darah secara signifikan dan penurunannya telah mencapai normal. Hasil identifikasi dengan KGC-MS menunjukkan kandungan dominan fraksi kloroform yang dieluasi dengan metanol-amoniak adalah golongan asam lemak tidak jenuh berantai panjang yaitu asam heksanoat, metil heksadekanoat, metil 9-oktadekanoat, butil oleat, asam 9-oktadekanoat, asam 1,2-benzendikarboksilat, dan Aplistearilasetat. Di samping asam lemak tidak jenuh, ditemukan pula senyawa alkaloid yaitu Nordextromethorphan. Dapat disimpulkan bahwa fraksi kloroform herba ciplukan mempunyai efek antidiabetes dan mempunyai kandungan senyawa golongan asam lemak tidak jenuh dan alkaloid Nordextromethorphan.
