Sebuah tinjauan: Senyawa-senyawa flavonoid pada suku Araceae
Get PDFFlavonoids is one of the secondary metabolites and consists of two phenyl rings (A- and B-rings) connected by a three carbon bridge. Over 8000 kinds of flavonoids were reported from vascular plants and Bryophytes. This paper reviewed the flavonoid characters of the Araceae s.l. (including the Lemnaceae). Major flavonoids of the family were C-glycosylflavones with the exception for subfamilies Gymnostachydoideae and Orontioideae. Other flavonoid classes, i.e. anthocyanins, flavones, flavonols, flavan and proanthocyanidins, were reported in all subfamilies. Flavanone and C-glycosylflavanone were isolated from Spirodela polyrhiza and Anthurium binotii, respectively. However, dihydroflavonol, chalcone, dihydrochalcone, aurone, and isoflavonoids were not reported in the Araceae. Although Araceae s.l. is a large family consisting of ca. 3645 species and ca. 144 genera, flavonoids were surveyed only in 146 species of 48 genera, as far as known.Flavonoid merupakan salah satu metabolit sekunder dan terdiri dari dua cincin fenil (cincin A dan B) yang dihubungkan oleh jembatan tiga karbon. Lebih dari 8000 jenis flavonoid dilaporkan dari tumbuhan berpembuluh dan Bryophyta. Makalah ini mengulas karakter flavonoid dari suku Araceae s.l. (termasuk Lemnaceae). Sebagian besar flavonoid utama dari suku Araceae adalah C-glikosilflavon dengan pengecualian untuk anak suku Gymnostachydoideae dan Orontioideae. Jenis flavonoid lainnya, yaitu anthocyanin, flavon, flavonol, flavan, dan proanthocyanidins dilaporkan terdapat pada semua anak suku Araceae. Flavanon dan C-glikosil flavanon diisolasi masing-masing dari Spirodela polyrhiza dan Anthurium binotii. Namun demikian, dihydroflavonol, chalcone, dihydrochalcone, aurone, dan isoflavonoid tidak dilaporkan terdapat pada jenis-jenis dari suku Araceae yang telah diteliti. Meskipun Araceae s.l. merupakan suku tumbuhan besar yang terdiri atas sekitar 3645 jenis dan 144 marga, baru 146 jenis dari 48 marga yang diketahui kandungan flavonoidnya

PENINGKATAN KERAGAMAN Grammatophyllum scriptum (L.) Blume ASAL SULAWESI DENGAN IRADIASI SINAR GAMMA
Get PDFGrammatophyllum scriptum (L.) Blume or tiger orchid is one of Bogor Botanic Gardens’ collections which was collected from Sulawesi. Elongated stem of this species frequently occurred during in vitro propagation. Therefore, gamma irradiation was used in order to obtain mutation of protocorm. The aim of this study was to reduce the length of segment stem using gamma irradiation in order to generate rosette leaf arrangement as a candidate of superior mutant produced. Four doses of gamma irradiation were used viz. 0 Gy, 15 Gy, 30 Gy, and 45 Gy. Seeds were germinated in various modification media such as, modification of Knudson’C medium (KC and KCA), modification of VW medium, and modification of Hyponex medium. The result showed that VW modification medium gave best media for seeds germination. Subsequently, the protocorms growing in this medium were irradiated to create mutant. Based on data analysis showed that Lethal Dose 50 (LD 50) of protocorm G. scriptum was found in 43.46 Gy and for LD 20 was found in 20.9 Gy. Diverse stem morphology occurred in 15–30 Gy dose irradiation, meanwhile 45 Gy irradiation caused entire protocorms fail to recovery and finally dead.Kebun Raya Bogor memiliki koleksi anggrek macan (Grammatophyllum scriptum (L.) Blume) dan salah satu koleksinya berasal dari Sulawesi. Pemanjangan batang jenis ini sering terjadi selama diperbanyak secara in vitro, sehingga diperlukan adanya mutasi protokorm dengan menggunakan sinar gamma. Tujuan dari penelitian ini adalah memperpendek morfologi ruas batang dengan iradiasi gamma, agar didapatkan susunan daun lebih roset, yang nantinya dapat dijadikan sebagai kandidat bibit unggul dari mutan-mutan yang dihasilkan. Iradiasi dilakukan dengan menggunakan dosis 0, 15, 30, dan 45 Gray (Gy). Media yang digunakan untuk menyemai biji adalah modifikasi media Knudson’C (KC dan KCA), modifikasi VW, dan modifikasi Hyponex. Media VW yang dimodifikasi menunjukkan hasil perkecambahan terbaik dan untuk selanjutnya protokorm yang tumbuh pada media tersebut diiradiasi untuk menghasilkan mutan. Hasil analisis menunjukkan Lethal Dosis (LD) 50 protokorm G. scriptum pada dosis iradiasi 43,46 Gy, sedangkan LD 20 terletak pada dosis iradiasi 20,9 Gy. Keragaman morfologi ruas batang anggrek hasil iradiasi terjadi pada dosis iradiasi 15–30 Gy, sementara dosis iradiasi 45 Gy tidak dapat melewati tahap pemulihan sehingga eksplan mengalami kematian 100%
