ABSTRAK: Pada penelitian ini dilakukan pengembangan formula sediaan hand and body cream dengan memanfaatkan sumber antioksidan yang dimiliki oleh dua jenis ekstrak etanol yaitu ekstrak bunga pacar air merah (Impatiens balsamina L.) dan bunga gemitir (Tagetes erecta L.) dengan taraf perlakuan sebesar 1% dari masing-masing ekstrak (FPM dan FG) dan campuran 0,5% ekstrak pacar air merah dan 0,5% ekstrak gemitir (FCPMG). Pengujian terhadap  produk dilakukan pada sifat fisikokimia  meliputi pH, viskositas, aktivitas antioksidan, angka lempeng total mikroba, dan ukuran partikel. Berdasarkan hasil pengujian produk hand and body cream yang dihasilkan memiliki antioksidan yang cukup tinggi sebagai produk perawatan tubuh dengan penambahan 1% ekstrak etanol pacar air merah, gemitir dan campuran dari kedua ekstrak etanol. Kualitas produk hand and body cream yang dihasilkan baik dan memenuhi standar mutu SNI dari aspek nilai pH, viskositas, dan nilai ALT. Warna yang dihasilkan mulai dari warna kuning kemerahan sampai dengan warna kuning, dan partikel yang dimiliki oleh produk adalah nanopartikel dengan sistem polidispersi. ABSTRACT: Formulations of hand and body creams using ethanol extracts of flowers of red Impatiens balsamina L. And Tagetes erecta L. As antioxidant sources have been developed.  One percent of  extracts (FPM and FG) and the mixture of 0.5% each extracts (FCPMG) were added to the basic formula. The analysis of physicochemical properties of the products was conducted including pH, viscosity, antioxidant activity, the size of the particles, and total microbial plate numbers. Based on the results, the quality of the hand and body creams meet the national standard of Indonesia (SNI) regarding to pH, viscosity, and the total microbial numbers. The colours of the hand and body creams resulted are reddish yellow to yellow with polydispersion nanoparticles.

Abstract Background: Flower development directly affects fruit production in tomato. Despite the framework mediated by ABC genes have been established in Arabidopsis, the spatiotemporal precision of floral development in tomato has not been well examined.Results: Here, we analyzed a novel tomato stamenless like flower (slf) mutant in which the development of stamens and carpels is disturbed, with carpelloid structure formed in the third whorl and ectopic formation of floral and shoot apical meristem in the fourth whorl. Using bulked segregant analysis (BSA), we assigned the causal mutation to the gene Solanum lycopersicum GT11 (SlGT11) that encodes a transcription factor belonging to Trihelix gene family. SlGT11 is expressed in the early stages of the flower and the expression becomes more specific to the primordium position corresponding to stamens and carpels in later stages of the floral development. Further RNAi silencing of SlGT11 verifies the defective phenotypes of the slf mutant. The carpelloid stamen in slf mutant indicates that SlGT11 is required for B-function activity in the third whorl. The failed termination of floral meristem and the occurrence of floral reversion in slf indicate that part of the C-function requires SlGT11 activity in the fourth whorl. Furthermore, we find that at higher temperature, the defects of slf mutant are substantially enhanced, with petals transformed into sepals, all stamens disappeared, and the frequency of ectopic shoot/floral meristem in fourth whorl increased, indicating that SlGT11 functions in the development of the three inner floral whorls. Consistent with the observed phenotypes, it was found that B, C and an E-type MADS-box genes were in part down regulated in slf mutants.Conclusions: Together with the spatiotemporal expression pattern, we suggest that SlGT11 functions in floral organ patterning and maintenance of floral determinacy in tomato.

Abstract Impatiens balsamina is an annual herb thought to be native to India and Myanmar. It has been widely introduced outside of its native range as an ornamental to Europe, Asia, the Americas, Oceania and some parts of tropical Africa. It has escaped from cultivation and become naturalized in disturbed sites and semi-natural habitats including secondary forests and forest edges. It spreads by seed and also vegetatively by stem fragments and can form dense stands in forest understory inhibiting germination and the establishment of seedlings, displacing native plant species. It is thought to be invasive to many tropical and subtropical islands in Oceania and the Caribbean as well as Costa Rica, Peru, the Galapagos Islands, the Philippines and parts of India.
