Objective: Covid 19 is a disease that infects cells in the airway lining the alveoli. This disease is caused by a virus named SarsCoV2. One way to handle it is to increase immunity. The body itself consists of immune system organs. One component of the immune system that is very important in protecting the body against the SARS-Cov-2 virus attack is Cluster of Differentiation 8+ T (CD8+T). CD8+T is one of the components of the adaptive immune system or often known as the specific immune system and is cytotoxic, so it is called Cluster of Differentiation8 +T. One of the plants used by the community to increase endurance is Sungkai (Peronema canescens Jack.). This study aims to see its activity against Cluster of Differentiation 8+ T (CD8+T). Methods: Sungkai leaf powder was extracted using 70\% ethanol solvent and evaporated using a rotary evaporator to obtain ethanol extract and fractionated with n-hexanes and isolated to obtain active isolates of sungkai leaves against the immune system. Isolates obtained from the isolation of the active fraction of n hexanes that have been tested as immunostimulants in previous studies. This study used test animals, namely male white mice of the wistar strain as many as 30 mice consisting of 5 heads for each group. Group I is a control group that is not given treatment and groups II, III, IV, V and VI are given exposure to the Sars CoV2 virus antigen that causes Covid 19 disease, namely using one of the Covid19 vaccines, namely the 0.0013 mL Moderna vaccine which is given Intra Muscular. Groups II, III, IV, V are treatment groups induced with Sars CoV2 antigen and given a test preparation, namely sungkai leaf isolate with 3 dose variations, namely 1, 10 and 100 mg/kg bw given orally, and group VI was given stimuno 50 mg/kgbw as a comparison. Results: From the results of immunostimulant testing of sungkai leaf isolate, it was found that stigmasterol has an immunostimulant effect in increasing Cluster of Differentiation 8 + T (CD8 + T) in the body given SARS-CoV-2 virus antigen. Significant results were seen in the 100 mg/kg bw dose group which increased CD8+T by 53.93 ng/dl. Based on statistical tests conducted in the form of ANOVA tests, CD8+T also showed significant differences with a significance value of \<0.05. Conclusion: Stigmasterol isolate of sungkai leaf has the effect of increasing Cluster of Differentiation 8+ T (CD8+T) levels in the body given exposure to SARS-CoV 2 virus antigens.

Background: Adhatoda vasica Nees (Acanthaceae) is a well-known medicinal plant used for the treatment of respiratory disorders such as asthma and bronchitis. Objective: To develop a simple and precise RP-HPLC method for the simultaneous assessment of lupeol, stigmasterol and β-sitosterol of various extracts of Adhatoda vasica Nees. Materials and Methods: The compounds were separated on RP-Phenomenex C18 (250mm{\texttimes}4.6mm; 5μ) column with a mobile phase comprising of 0.1\%v/v formic acid in water and methanol (28:82\%v/v) splashed at a flow of 0.8mL/min with PDA detector at 208nm. Results: The retention time of lupeol, stigmasterol and β-sitosterol was found to be 16.89, 18.26 and 20.72 minutes respectively. The amount of lupeol was abundant in hexane extract (0.952\%w/w) and formulation III (23.72ng/g) whereas, stigmasterol (0.285\%w/w) and β-sitosterol (8.649\%w/w) was highly abundant in chloroform extract and formulation I stigmasterol (2.57ng/g) and β-sitosterol (0.98ng/g). The optimized method was validated for different parameters and all the validated constraints were within the limits as per ICH guidelines. The proposed method was linear over the concentration range of 12.5-200μg/mL with correlation coefficients greater than 0.997. The LOD and LOQ values of lupeol, stigmasterol and β-sitosterol were found to be 0.66, 5.64 and 12.8μg/mL and 2.01, 17.10 and 36.62μg/mL respectively. Conclusion: To conclude, the developed method for the simultaneous estimation of lupeol, stigmasterol and β-sitosterol was simple, precise, accurate and thus reliable for the quality control investigations of crude drugs and its herbal formulations.

Introduction: This study was designed to evaluate the phytocomponents present in aerial part and in vitro induced callus methanol extracts of Dipterygium glaucum by Gas Chromatography-Mass Spectrometry (GC-MS) technique. Methods: GC-MS analysis of aerial part sample and callus produced from leaf of D. glaucum extracted in methanol solvents was performed using GC-MS QP 2010 Plus (Shimadzu, Japan) system comprising an auto sampler (AOC-20i) and a gas chromatograph interfaced to a mass spectrometer. Results: This study was carried out to identified and comparative analysis of bioactive phytochemicals from aerial part extract and callus extract of D. glaucum. This analysis revealed that both the extracts have 69 different types of phytochemical components in varying quantities. Some of the important phytochemical compounds were Stigmasterol, β-sitosterol, γ-sitosterol, Campesterol, Squalene, n-Hexadecanoic acid, Stearic acid, Myristic acid, Quinazoline, Linalyl acetate etc. These chemical compounds have anticancer, antitumor, anti-inflammatory, antidiabetic and antioxidants properties. Conclusion: This study represents the detection and identification of different phytochemical compounds from aerial part and callus extract of D. glaucum. Thus, due to the presence of various important bioactive phytocomponents this plant is recommended as a pharmaceutically important plant.

Introduction: Hoya plants are also called wax plants due to the waxy appearance of their leaves and flowers. Most species are cultivated as ornamental plants. In the Philippines, there are at least 109 species of Hoya; 88 of these are endemic to the country. One of the endemic species is Hoya meliflua often confused with H. diversifolia, which can also be found in other countries. This study is part of our research on the chemical constituents of Philippine native Hoyas. Methods: The compounds were isolated by silica gel chromatography and identified by NMR spectroscopy. Results: Chemical investigation of the dichloromethane extract from the leaves of Hoya meliflua afforded squalene and mixtures of β-amyrin (1a), α-amyrin (1b) and lupeol (1c) in about 1:1:0.25 ratio; oleanone (2a), ursenone (2b) and lupenone (2c) in about 1:1:0.3 ratio; β-amyrin cinnamate (3a), α-amyrin cinnamate (3b) and lupenyl cinnamate (3c) in about 0.5:0.3:1 ratio; and β-sitosterol and stigmasterol in about 5:1 ratio. Conclusion: The results of our study indicate that Hoya meliflua shares similar chemical characteristics with other members of the genus Hoya. The triterpenes and sterols obtained from H. meliflua were also identified from other Hoya species. It is interesting to note that although most Hoya plants have no known biological activity and medicinal property, the compounds isolated from H. meliflua possess diverse bioactivities.
