A New Pyranoxanthone from the Stem Bark of Calophyllum inophyllum

Letters in Organic Chemistry (2011)

Siau Hui Mah Gwendoline Cheng Lian Ee Mawardi Rahmani Yun Hin Taufiq‐Yap Rusea Go

The stem bark of Calophyllum inophyllum gave one new prenylated dipyranoxanthone inophinone (1), together with two other xanthones, inophyllin A (2) and caloxanthone B (3) and three common triterpenes, friedelin (4), stigmasterol (5) and betulinic acid (6). 1D and 2D NMR spectral data (1H, 13C, DEPT, COSY, HMBC & HMQC) were used to elucidate the structures of these compounds Keywords: Inophinone, dipyranoxanthone, Calophyllum inophyllum, Guttiferae, xanthones, inophyllin, caloxanthone, triterpenes, friedelin, stigmasterol

VANILLA YERSINIANA (ORCHIDACEAE), A NEW RECORD FOR PENINSULAR MALAYSIA

REINWARDTIA (2021)

Muhammad Ikhwanuddin Mat Esa Farah Alia Nordin Rusea Go Akmal Raffi

MAT ESA, M. I., NORDIN, F. A., GO, R. & RAFFI, A. 2021. Vanilla yersiniana (Orchidaceae), a new record for Peninsular Malaysia. Reinwardtia 20(2): 51−55. — The genus Vanilla Plum. ex Mill. from Peninsular Malaysia is now enriched with the discovery of a newly recorded species, Vanilla yersiniana that made up its regional diversity to eight taxa. This species was documented from two adjacent secondary lowland forests in Perak; further south to the southern tail of Thailand. This paper describes the first record of V. yersiniana in Peninsular Malaysia with some highlights of its morphology and ecology. The data presented will add to the present state of knowledge on the species botanical profile.

Effect of herbal combination and natron addition on the antioxidant properties of Guiera senegalensis J. F. Gmel (combretaceae) aqueous leaf extract

Deleted Journal (2017)

Siti Khadijah Sulaiman Rusea Go

Guiera senegalensisis among the medicinal herbs traditionally used for the management of maternal conditions in Katsina State, Nigeria. In the course of its preparation, G. senegalensis is, in most cases, mixed with Ipomoea asarifolia and Euphorbia balsamifera. Small amount of natron is often added in order to enhance the palatability of the herbal preparation. In this study, we investigated the impact of these two phenomena on the antioxidant properties of G.senegalensis . Phenolic antioxidant contents were assessed using Total Phenolic Content (TPC) and Total Flavonoid Content (TFC) calorimetric assays. Antioxidant activity on the other hand was evaluated using 2,2ꞌ-diphenyl-1- picrylhydrazyl (DPPH) radical scavenging activity, Ferric Reducing Antioxidant Power (FRAP) and Total Antioxidant Capacity (TAC) assays. Herbal combination and natron addition were found to significantly (P <0.05) affect the antioxidant properties of G. senegalensis . High antioxidant properties were observed when G. senegalensis was extracted alone compared to when extracted in combination with either I. asarifolia or E. balsamifera or both. Although it increased the TPC and TFC values, natron addition was also found to be detrimental to the antioxidant activities of G. senegalensis .

Phylogenetic of the Orchid Genus Coelogyne Inferred from Morphological Characteristics and Internal Transcribed Spacer (ITS) Sequence Data

Rusea Go Seok-Yien YONG Christina Janna Ong Abdullah Kok Hon Yoh

The phylogenetic relationships among the Peninsular Malaysian orchid genus Coelogyne were studied by morphological characteristics and by sequencing the internal transcribed region (ITS) from the nuclear ribosomal DNA (nrDNA). Coelogyne is a large genus of about 200 species distributed in pantropical areas from the Himalayas, Sri Lanka, India, Southern China and throughout South East Asia to Papua New Guinea. The widely accepted previous classification system was exclusively based on floral morphology. There were very few molecular systematic studies of Coelogyne done in Peninsular Malaysia thus far. In this study, 59 Coelogyne taxa were collected from throughout Peninsular Malaysia and 57 of them were identified to the species level. To study the phylogeny of this genus, morphological characters were utilized together with molecular evidences to generate the systematic hypotheses. Cluster analysis was performed using both the vegetative and floral characters. The results showed that three sections of Peninsular Malaysian Coelogyne, namely Longifoliae, Speciosae and Fuliginosae were sister groups which were more closely related by forming one clade than they were with the other sections. Another clade consisted of four other sections, namely Flaccidae, Coelogynae, Tomentosae and Verrucosae. Molecular phylogenies obtained by using the Neighbour Joining method revealed the close relationship between the sections Tomentosae and Verrucosae, whereas usage of the Maximum Likelihood method demonstrated that three sections namely Longifoliae, Speciosae and Fuliginosae were sister groups since they formed a single clade.

PHYLOGENETIC ANALYSIS AMONG FOUR SECTIONS OF THE GENUS DENDROBIUM SW. (ORCHIDACEAE) BASED ON LOW COPY NUCLEAR GENE (XDH) SEQUENCES IN PENINSULAR MALAYSIA

Maryam Moudi Rusea Go

The present study focused on the molecular phylogeny of the four sections (Aporum, Crumenata, Strongyle, and Bolbidium) of the genus Dendrobium SW. (Orchidaceae) based upon low copy nuclear gene, Xanthine Dehydrogenase (Xdh) sequences using maximum parsimony (MP), maximum likelihood (ML) and Bayesian (BI) methods. Single and low copy nuclear genes have been increasingly used in phylogenetic reconstruction because they contain large amounts of genetic information and are biparentally inherited. Classifications based on morphological characters have not been able to clearly divide these four sections and neither do they support their monophyletic origins. Therefore, detailed analysis using molecular data is required to ascertain their status. This study includes 20 species of genus Dendrobium and 2 species from genus Bulbophyllum (section Sestochilus) as outgroup taxa. According to the results, the aligned sequences consisted of 733 nucleotide characters of which 131characters were parsimony informative. The analysis revealed that the nuclear genes can be reliable marker for the phylogenetic study of genus Dendrobium. The results suggested that the four sections are probably best considered as one section instead of four and based on the International Code of Botanical Nomenclature (ICBN) rules can be named as section Aporum for this new classification.

Two new species of Dendrobium Sect. Calcarifera (Orchidaceae) from Terengganu, Peninsular Malaysia

Edward Entalai Besi Dome Nikong Muskhazli Mustafa Rusea Go

Two new species, Dendrobium ainiae R. Go et E. E. Besi and Dendrobium ruseae E. E. Besi et Dome belonging to Sect. Calcarifera are described and illustrated from Terengganu, Peninsular Malaysia. These species are so far known from a population in lowland dipterocarp forest. A field key to the Peninsular Malaysian taxa of Dendrobium Sect. Calcarifera including Dendrobium chewiorum is also provided.

Floral micromorphology and transcriptome analyses of a fragrant Vandaceous Orchid, Vanda Mimi Palmer, for its fragrance production sites

BMC Research Notes (2017)

Conie Toh Mohd Hairul Ab. Rahim Nooraini Mohd Ain Parameswari Namasivayam Rusea Go

Vanda Mimi Palmer (VMP) is commercially valuable for its strong fragrance but little is known regarding the fragrance production and emission sites on the flowers.Olfactory perception detected fragrance only from the petals and sepals. Light and Environmental Scanning Electron microscopy analyses on fresh tissues showed distributions of stomata and trichomes concentrated mostly around the edges. These results paralleled the rich starch deposits and intense neutral red stain, indicating strong fragrance and trichomes as potential main fragrance release sites. Next Generation Sequencing (NGS) transcriptomic data of adaxial and abaxial layers of the tissues showed monoterpene synthase transcripts specifically linalool and ocimene synthases distributed throughout the tissues. qPCR analyses taken at different time points revealed high levels of linalool and ocimene synthases transcripts in the early morning with maximal level at 4.00 am but remained low throughout daylight hours.Knowledge of the VMP floral anatomy and its fragrance production characteristics, which complemented our previous molecular and biochemical data on VMP, provided additional knowledge on how fragrance and flower morphology are closely intertwined. Further investigation on the mechanisms of fragrance biosynthesis and interaction of potential pollinators would elucidate the evolution of the flower morphology to maximize the reproduction success of this plant.
