Penapisan fitokimia daun paliasa menunjukkan adanya kandungan senyawa alkaloid, triterpenoid dan steroid. Senyawa alkaloid terpenoid berupa sikloartane triterpenoid alkaloid.  Daun paliasa diduga berperan aktif sebagai senyawa antiplasmodium.  Namun, perlu dilakukan pengkajian lebih lanjut untuk memastikan jenis senyawa aktif tersebut serta mekanismenya sebagai antiplasmodiumPaliasa (Kleinhovia hospita) is known as a plant that has been used empirically for malaria treatment, especially in Eastern Indonesia. However, scientific publications regarding to the antiplasmodial activity of these natural resources are still limited. The aim of this study was to examine the potency of paliasa leaves as antiplasmodial against Plasmodium falciparum parasite. The procedure included sample and extract preparation, antiplasmodial in vitro activity testing on P. falciparum strain 3D7, and phytochemical screening using Thin Layer Chromatography (TLC). The extracts and fractions were prepared through maceration process for 72 hours with 96% ethanol, then continued with multilevel liquid-liquid partition using hexane, ethyl acetate and 96% methanol. Antiplasmodial in vitro testing showed that ethyl acetate (IC50 1.08 µg.ml-1) and hexane (IC50 1.24 µg.ml-1) fractions were include to the highly activity category. The research samples contained alkaloids, triterpenoids and steroids as the major compounds. The terpenoid alkaloid compound was a cycloartane triterpenoid alkaloid that had been isolated from paliasa leaves. Therefore, it is assumed that the leaf of palasia has a compound with antiplasmodial activity. However, more research needs to be done to determine the active compound and the antiplasmodial mechanisms involve

Autentikasi Centella asiatica (L.) Urb. (Pegagan) dan Adulterannya Berdasarkan Karakter Makroskopis, Mikroskopis, dan Profil Kimia

Pegagan or Centella asiatica (L.) Urb. empirically used as medicinal plant and scientifically can be used as antihypertension based on the results of the Jamu Saintification. Raw materials from C. asiatica have the potential to occur adulteration or incorrect use of plants species. There are two species of plants that have the potential to become adulterants of C. asiatica, namely Hydrocotyle verticillata and Merremia emarginata. Thus, the purpose of this study is to authenticate from Pegagan by comparing the macroscopic, microscopic, and chemical profiles of C. asiatica, H. verticillata, and M. emarginata. The method of data collection is done by purposive sampling using form intruments to record macroscopic and microscopic characters, while the chemical profiles are tested using thin layer chromatography methods to determine the content of asiaticosides in both potential adulterants species. The research was conducted at three sampling points: Central Java (Tawangmangu), West Java (Bogor), and East Java (Malang), while for laboratory research activities carried out at B2P2TOOT, Tawangmangu. The results showed macroscopically unique and easy distinguishing characters between C. asiatica and potential adulterant species H. verticillata is a leaf shape, whereas C. asiatica with M. emarginata are leaf-type appearance characters. The character of the simplicia leaf shape between C. asiatica and H. verticillata can be a distinct differentiator characters. Anatomical characters and powder fragments that can be used as a differentiator characters between C. asiatica and H. verticillata are the presence of pith on the stalk and stolon, the type of stomata, and the presence of trichomes. Authentication of simplicia powder of H. verticillata as an adulterant potential of C. asiatica with TLC, can be easily known by the absence of asiaticosides in these simplicia so that H. verticillata cannot be a substitute species for C. asiatic

The treatment of BAP 4 mg/L + NAA 0.5 mg/L provides better performance for the number of leaves, and BAP 3 mg/L produced the best response regarding the number of shoots. Furthermore, BAP 1 mg/L + NAA 1 mg/L produced the best response to shoot height and number of leaves, and BAP 3 mg/L + NAA 0.5 mg/L generated the best response to root length. Based on the research, BAP 3 mg/L is the optimal treatment

Karakterisasi Minyak Atsiri dari Simplisia Basah Ranting dan Daun sebagai Alternatif Subtitusi Kulit Batang Cinnamomum burmannii Blume

The bark of Cinnamomum burmannii Blume is the main raw material of Cinnamomum oil because its cinnamaldehyde content is higher than in the other parts. This condition lead to the exploitation of Cinnamomum burmannii Blume bark without any cultivation effort, thus it can cause the raw material scarcity. Twigs and leaves of Cinnamomum burmannii Blume are also known to contain cinnamaldehyde therefore it provide a potential alternative source of cinnamaldehyde. The purpose of this research is to investigate the characteristic of Cinnamomum burmannii Blume essential oil which includes refractive index, profiling of chemical constituent and percentage of cinnamaldehyde as a marker compound. This research used three fresh Cinnamomum burmannii Blume simplicia of bark, twigs and leaves from two selected growing locations: Tawangmangu and Purwokerto. Simple water distillation method was conducted, together with characterization and refractive index using refractometer, followed by qualitative and quantitative analysis with Thin Layer Chromatography (TLC) and Gas Chromatography (GC). The results showed Cinnamomum burmannii Blume oil derived from bark, twig and leaf have different profiles, but all have cinnamaldehyde as the main component. The leaf produces higher essential oil yield percentage compared to the twig with a cinnamaldehyde content that is comparable to the bark by 50% of cinnamaldehyde content in cinnamomum bark oil

Aktivitas Antimalaria Daun Gempol (Nauclea orientalis (L.) L) terhadap Plasmodium falciparum

Abstract The use of gempol (Nauclea orientalis (L.) L) stem as a malaria medicine has been empirically and scientifically proven. This condition encourages exploitation which can lead to scarcity of raw materials. Substitution of plant parts as raw material for medicine is one of the innovations that can be done for the sustainability of the plant species. Leaves are one part of the plant that is often used as a raw material for medicine. The selection of leaves as the main ingredient has many advantages over other parts. Until now, research related to the antimalarial bioactive potential of N. orientalis (L.) L leaves has not been published. Therefore, this study aimed to explore the potential for leaf antimalarial activity as an alternative to substitution of stem parts. The leaf extract of N. orientalis (L.) L was prepared by maceration method with 96% ethanol then fractionation was carried out in stage using hexane, ethyl acetate and methanol as solvents. Antimalarial activity testing was carried out in vitro against Plasmodium falciparum 3D7 and Thin Layer Chromatography (TLC) for screening phytochemical compounds in each sample. The hexane solvent was known to produce the most optimum extract by with a yield of 20%. The antimalarial activity of the hexane (IC 50 1.93 μg/mL) and methanol (IC 3.91 μg/ mL) fractions were classified as ‘very active’ and had a tendency to be able to compete with chloroquine phosphate activity. The potential for antimalarial activity in both samples was influenced by the content of alkaloids, steroids, flavonoids and terpenoids which had been developed as active ingredients for malaria drugs. The results of this study indicate that the leaves of Nauclea orientalis (L.) L have the potential to be developed as an alternative to malaria medicine. Abstrak Pemanfaatan batang gempol (Nauclea orientalis (L.) L) sebagai obat malaria telah terbukti secara empiris dan ilmiah. Kondisi tersebut mendorong terjadinya eksploitasi hingga dapat berujung pada kelangkaan bahan baku. Substitusi bagian tumbuhan sebagai bahan baku obat merupakan salah satu inovasi yang dapat dilakukan untuk keberlanjutan hidup spesies tumbuhan tersebut. Daun merupakan salah satu bagian tumbuhan yang sering digunakan sebagai bahan baku obat. Pemilihan daun sebagai bahan utama memiliki banyak kelebihan dibandingkan bagian lainnya. Penelitian terkait potensi bioaktif antimalaria daun Nauclea orientalis (L.) L hingga saat ini belum dipublikasikan. Oleh karena itu, penelitian ini bertujuan untuk menggali potensi aktivitas antimalaria daun sebagai alternatif subtitusi bagian batang. Ekstrak daun Nauclea orientalis (L.) L disiapkan dengan metode maserasi dengan etanol 96%, kemudian dilakukan fraksinasi cair-cair bertingkat menggunakan pelarut heksana, etil asetat, dan metanol. Pengujian aktivitas antimalaria dilakukan secara in vitro terhadap Plasmodium falciparum 3D7 dan Kromatografi Lapis Tipis (KLT) untuk penapisan senyawa fitokimia pada masingmasing sampel. Pelarut heksana diketahui menghasilkan ekstrak paling optimum dengan rendemen 20%. Aktivitas antimalaria fraksi heksana (IC 50 1,93 µg/mL) dan metanol (IC 3,91 µg/mL) yang tergolong dalam kategori ‘sangat aktif, serta memiliki kecenderungan mampu bersaing dengan aktivitas klorokuin fosfat. Potensi aktivitas antimalaria pada kedua sampel tersebut dipengaruhi oleh kandungan senyawa alkaloid, steroid, flavonoid dan terpenoid yang telah banyak dikembangkan sebagai bahan aktif obat malaria. Hasil penelitian ini menunjukkan bahwa daun Nauclea orientalis (L.) L berpotensi untuk dikembangkan sebagai alternatif obat malaria
